Speech intelligibility of the callsign acquisition test in a quiet environment. (1/147)

This paper reports on preliminary experiments aimed at standardizing speech intelligibility of military Callsign Acquisition Test (CAT) using average power levels of callsign items measured by the Root Mean Square (RMS) and maximum power levels of callsign items (Peak). The results obtained indicate that at a minimum sound pressure level (SPL) of 10.57 dBHL, the CAT tests were more difficult than NU-6 (Northwestern University, Auditory Test No. 6) and CID-W22 (Central Institute for the Deaf, Test W-22). At the maximum SPL values, the CAT tests reveal more intelligibility than NU-6 and CID-W22. The CAT-Peak test attained 95% intelligibility as NU-6 at 27.5 dBHL, and with CID-W22, 92.4% intelligibility at 27 dBHL. The CAT-RMS achieved 90% intelligibility when compared with NU-6, and 87% intelligibility score when compared with CID-W22; all at 24 dBHL.  (+info)

Evaluation method for hearing aid fitting under reverberation: comparison between monaural and binaural hearing aids. (2/147)

Some hearing-impaired persons with hearing aids complain of listening difficulty under reverberation. No method, however, is currently available for hearing aid fitting that permits evaluation of hearing difficulty caused by reverberations. In this study, we produced speech materials with a reverberation time of 2.02 s that mimicked a reverberant environment (a classroom). Speech materials with reverberation times of 0 and 1.01 s were also made. Listening tests were performed with these materials in hearing-impaired subjects and normal-hearing subjects in a soundproof booth. Listening tests were also done in a classroom. Our results showed that speech material with a reverberation time of 2.02 s had a decreased listening-test score in hearing-impaired subjects with both monaural and binaural hearing aids. Similar results were obtained in a reverberant environment. Our findings suggest the validity of using speech materials with different reverberation times to predict the listening performance under reverberation of hearing-impaired persons with hearing aids.  (+info)

Decline of speech understanding and auditory thresholds in the elderly. (3/147)

A group of 29 elderly subjects between 60.0 and 83.7 years of age at the beginning of the study, and whose hearing loss was not greater than moderate, was tested twice, an average of 5.27 years apart. The tests measured pure-tone thresholds, word recognition in quiet, and understanding of speech with various types of distortion (low-pass filtering, time compression) or interference (single speaker, babble noise, reverberation). Performance declined consistently and significantly between the two testing phases. In addition, the variability of speech understanding measures increased significantly between testing phases, though the variability of audiometric measurements did not. A right-ear superiority was observed but this lateral asymmetry did not increase between testing phases. Comparison of the elderly subjects with a group of young subjects with normal hearing shows that the decline of speech understanding measures accelerated significantly relative to the decline in audiometric measures in the seventh to ninth decades of life. On the assumption that speech understanding depends linearly on age and audiometric variables, there is evidence that this linear relationship changes with age, suggesting that not only the accuracy but also the nature of speech understanding evolves with age.  (+info)

A comparison of word-recognition abilities assessed with digit pairs and digit triplets in multitalker babble. (4/147)

This study compares, for listeners with normal hearing and listeners with hearing loss, the recognition performances obtained with digit-pair and digit-triplet stimulus sets presented in multitalker babble. Digits 1 through 10 (excluding 7) were mixed in approximately 1,000 ms segments of babble from 4 to -20 dB signal-to-babble (S/B) ratios, concatenated to form the pairs and triplets, and recorded on compact disc. Nine and eight digits were presented at each level for the digit-triplet and digit-pair paradigms, respectively. For the listeners with normal hearing and the listeners with hearing loss, the recognition performances were 3 dB and 1.2 dB better, respectively, on digit pairs than on digit triplets. For equal intelligibility, the listeners with hearing loss required an approximately 10 dB more favorable S/B than the listeners with normal hearing. The distributions of the 50% points for the two groups had no overlap.  (+info)

Use of 35 words for evaluation of hearing loss in signal-to-babble ratio: A clinic protocol. (5/147)

Data from earlier studies that presented 70 words at 24 to 0 dB signal-to-babble (S/B) ratios indicated that most young listeners with normal hearing required 0 to 6 dB S/B ratios to attain 50% correct word recognition. Older listeners with hearing loss often required a >12 dB S/B ratio to attain 50% correct word recognition. In our study, we converted the Words in Noise test from one 70-word list into two 35-word lists for quicker administration by clinicians. Using baseline data from previous studies, we used two strategies to randomize the 35-word lists: based on recognition performance at each S/B ratio and based on recognition performance only. With the first randomization strategy, the 50% correct word-recognition points on the two lists differed by 0.5 dB for 72 listeners with hearing loss. With the second randomization strategy, 48 listeners with hearing loss performed identically on the two lists.  (+info)

Consistency of sentence intelligibility across difficult listening situations. (6/147)

PURPOSE: The extent to which a sentence retains its level of spoken intelligibility relative to other sentences in a list under a variety of difficult listening situations was examined. METHOD: The strength of this sentence effect was studied using the Central Institute for the Deaf Everyday Speech sentences and both generalizability analysis (Experiments 1 and 2) and correlation (Analyses 1 and 2). RESULTS: Experiments 1 and 2 indicated the presence of a prominent sentence effect (substantial variance accounted for) across a large range of group mean intelligibilities (Experiment 1) and different spectral contents (Experiment 2). In Correlation Analysis 1, individual sentence scores were found to be correlated across listeners in each group producing widely ranging levels of performance. The sentence effect accounted for over half of the variance between listener-ability groups. In Correlation Analysis 2, correlations accounted for an average of 42% of the variance across a variety of listening conditions. However, when the auditory data were compared to speech-reading data, the cross-modal correlations were quite low. CONCLUSIONS: The stability of relative sentence intelligibility (the sentence effect) appears across a wide range of mean intelligibilities, across different spectral compositions, and across different listener performance levels, but not across sensory modalities.  (+info)

Audiological evaluation of affected members from a Dutch DFNA8/12 (TECTA) family. (7/147)

In DFNA8/12, an autosomal dominantly inherited type of nonsyndromic hearing impairment, the TECTA gene mutation causes a defect in the structure of the tectorial membrane in the inner ear. Because DFNA8/12 affects the tectorial membrane, patients with DFNA8/12 may show specific audiometric characteristics. In this study, five selected members of a Dutch DFNA8/12 family with a TECTA sensorineural hearing impairment were evaluated with pure-tone audiometry, loudness scaling, speech perception in quiet and noise, difference limen for frequency, acoustic reflexes, otoacoustic emissions, and gap detection. Four out of five subjects showed an elevation of pure-tone thresholds, acoustic reflex thresholds, and loudness discomfort levels. Loudness growth curves are parallel to those found in normal-hearing individuals. Suprathreshold measures such as difference limen for frequency modulated pure tones, gap detection, and particularly speech perception in noise are within the normal range. Distortion otoacoustic emissions are present at the higher stimulus level. These results are similar to those previously obtained from a Dutch DFNA13 family with midfrequency sensorineural hearing impairment. It seems that a defect in the tectorial membrane results primarily in an attenuation of sound, whereas suprathreshold measures, such as otoacoustic emissions and speech perception in noise, are preserved rather well. The main effect of the defects is a shift in the operation point of the outer hair cells with near intact functioning at high levels. As most test results reflect those found in middle-ear conductive loss in both families, the sensorineural hearing impairment may be characterized as a cochlear conductive hearing impairment.  (+info)

Evidence that cochlear-implanted deaf patients are better multisensory integrators. (8/147)

The cochlear implant (CI) is a neuroprosthesis that allows profoundly deaf patients to recover speech intelligibility. This recovery goes through long-term adaptative processes to build coherent percepts from the coarse information delivered by the implant. Here we analyzed the longitudinal postimplantation evolution of word recognition in a large sample of CI users in unisensory (visual or auditory) and bisensory (visuoauditory) conditions. We found that, despite considerable recovery of auditory performance during the first year postimplantation, CI patients maintain a much higher level of word recognition in speechreading conditions compared with normally hearing subjects, even several years after implantation. Consequently, we show that CI users present higher visuoauditory performance when compared with normally hearing subjects with similar auditory stimuli. This better performance is not only due to greater speechreading performance, but, most importantly, also due to a greater capacity to integrate visual input with the distorted speech signal. Our results suggest that these behavioral changes in CI users might be mediated by a reorganization of the cortical network involved in speech recognition that favors a more specific involvement of visual areas. Furthermore, they provide crucial indications to guide the rehabilitation of CI patients by using visually oriented therapeutic strategies.  (+info)

N2 - Suboptimal interfaces between cochlear implant (CI) electrodes and auditory neurons result in a loss or distortion of spectral information in specific frequency regions, which likely decreases CI users speech identification performance. This study exploited speech acoustics to model regions of distorted CI frequency transmission to determine the perceptual consequences of suboptimal electrode-neuron interfaces. Normal hearing adults identified naturally spoken vowels and consonants after spectral information was manipulated through a noiseband vocoder: either (1) low-, middle-, or high-frequency regions of information were removed by zeroing the corresponding channel outputs, or (2) the same regions were ...
Dr. Nils Morgenthaler, Vice President for Medical Affairs for the Bruker Daltonics Division, added: We and our collaborators now have several years of experience with the research-use-only (RUO) MALDI Sepsityper workflow, and the feedback from our customers and collaborators has been very positive. So far, 21 peer reviewed scientific publications have evaluated this approach, in which the RUO MALDI Sepsityper workflow has been shown to provide approximately 80% correct identification at the species level, with the remaining 20% mostly unidentified, and with essentially no relevant misidentifications at the genus level. With further recent improvements and expansion in the IVD MALDI Biotyper reference library, this already excellent identification performance directly from blood culture is expected to improve even further. The recent CE-labeling of the kit underlines Brukers strategy to provide more and more workflows for clinical routine use on the IVD MALDI Biotyper platform. We believe that ...
How to be a Package-Dealing Theist - In a recent NRO essay, Michael Novak accuses atheists of trying to have the cake of theism, while eating it too. Novaks analysis is such a well-distilled statement of common confusions, that its worthwile working through the worst of it. Novak says,. Atheism is a long-term project. It is not completed when one ceases believing in God. It is necessary to carry it through until one empties from the world all the conceptual space once filled by God. One must also, for instance, abandon the conviction that the events, phenomena, and laws of the world we live in (those of the whole universe) cohere, belong together, have a unity. What is born from chance may be ruled by chance, quite insanely.. Most atheists one meets, however, take up a position rather less rigorous. To the big question Did the world of our experience, with all its seeming intelligibility and laws, come into existence by chance, or by the action of an agent that placed that intelligibility ...

Our sound absorption materials and reverberation time reduction solutions include acoustic wall panels, ceiling-suspended acoustic panels, decorative melamine cubes, absorbent wall coverings matched to any colour you desire and our innovative Kinetics wave baffles designed to reduce reverberation time measurements in large, open spaces like arenas and gymnasiums. The strategic use of such effective sound absorption products (many have been officially rated Class C) can dramatically improve the listening environment.. For the uninitiated, Reverberation Time is calculated as the time it takes for a sound to to 60 decibels below its original level in a given environment. Rooms with lots of reflective surfaces that bounce sound around are referred to by acousticians as live. A room with a very short reverberation time is referred to as dead. By placing the right kind of sound absorption products in a live room, we can absorb unwanted sound, preventing it from creating distracting ...

Values of the speech intelligibility index (SII) were found to be different for the same speech intelligibility performance measured in an acoustic perception jury test with 35 human subjects and different background noise spectra. Using a novel method for in-vehicle speech intelligibility evaluation, the human subjects were tested using the hearing-in-noise-test (HINT) in a simulated driving environment. A variety of driving and listening conditions were used to obtain 50% speech intelligibility score at the sentence Speech Reception Threshold (sSRT). In previous studies, the band importance function for average speech was used for SII calculations since the band importance function for the HINT is unavailable in the SII ANSI S3.5-1997 standard. In this study, the HINT jury test measurements from a variety of background noise spectra and listening configurations of talker and listener are used in an effort to obtain a band importance function for the HINT, to potentially correlate the ...
We investigated how standard speech coders, currently used in modern communication systems, affect the intelligibility of the speech of persons who have common speech and voice disorders. Three standardized speech coders (viz., GSM 6.10 [RPE-LTP], FS1016 [CELP], FS1015 [LPC]) and two speech coders based on subband processing were evaluated for their performance. Coder effects were assessed by measuring the intelligibility of vowels and consonants both before and after processing by the speech coders. Native English talkers who had normal hearing identified these speech sounds. Results confirmed that (a) all coders reduce the intelligibility of spoken language; (b) these effects occur in a consistent manner, with the GSM and CELP coders providing the least degradation relative to the original unprocessed speech; and (c) coders interact with individual voices so that speech is degraded differentially for different talkers.. ...
The specific objective of this project is to assess the speech intelligibility using both subjective and objective methods of one of the new speech test methods developed at U.S. Army Research Lab called the Callsign Acquisition Test (CAT). This study is limited to the determination of speech intelligibility for the CAT in the presence of various background noises, such as pink, white, and multitalker babble.

article{8623633, abstract = {When making phone calls, cellphone and smartphone users are exposed to radio-frequency (RF) electromagnetic fields (EMFs) and sound pressure simultaneously. Speech intelligibility during mobile phone calls is related to the sound pressure level of speech relative to potential background sounds and also to the RF-EMF exposure, since the signal quality is correlated with the RF-EMF strength. Additionally, speech intelligibility, sound pressure level, and exposure to RF-EMFs are dependent on how the call is made (on speaker, held at the ear, or with headsets). The relationship between speech intelligibility, sound exposure, and exposure to RF-EMFs is determined in this study. To this aim, the transmitted RF-EMF power was recorded during phone calls made by 53 subjects in three different, controlled exposure scenarios: calling with the phone at the ear, calling in speaker mode, and calling with a headset. This emitted power is directly proportional to the exposure to RF ...

What youll notice is that the reverberant sound level is now stretching out between the syllables and actually starting to mask some of the sharp spikes of the consonants. That means that some of the syllables are being buried or masked by the reverberant noise. Depending on how far each new syllable is submerged into the reverberant noise, a listener will have varying degrees of difficulty in understanding those words. This is a bit like trying to listen to one person with a bunch of other people talking around you, it gets harder to pick out the sounds you want to hear from all the other conversations around you. The only difference here is that with the reverebrant sound field it is the same conversation repeated hundreds of times with a little bit of time offset.

Assessment of outcome of hearing aid fitting in children should contain several dimensions: audibility, speech recognition, subjective benefit and speech production. Audibility may be: determined by means of aided hearing thresholds or real-ear measurements. For determining speech recognition, methods different from those used for adult patients must be used, especially for children with congenital hearing loss. In these children the development of the spoken language and vocabulary has to be considered, especially when testing speech recognition but also with regard to speech production. Subjective assessment of benefit to a large extent has to rely on the assessment by parents and teachers for children younger than school age. However, several studies have shown that children from the age of around 7 years can usually produce reliable responses in this respect. Speech production has to be assessed in terms of intelligibility by others, who may or may not be used to the individual childs ...
Speech is the most important communication modality for human interaction. Automatic speech recognition and speech synthesis have extended further the relevance of speech to man-machine interaction. Environment noise and various distortions, such as reverberation and speech processing artifacts, reduce the mutual information between the message modulated inthe clean speech and the message decoded from the observed signal. This degrades intelligibility and perceived quality, which are the two attributes associated with quality of service. An estimate of the state of these attributes provides important diagnostic information about the communication equipment and the environment. When the adverse effects occur at the presentation side, an objective measure of intelligibility facilitates speech signal modification for improved communication.. The contributions of this thesis come from non-intrusive quality assessment and intelligibility-enhancing modification of speech. On the part of quality, the ...
Mainstream automatic speech recognition has focused almost exclusively on the acoustic signal. The performance of these systems degrades considerably in the real world in the presence of noise. On the other hand, most human listeners, both hearing-impaired and normal hearing, make use of visual information to improve speech perception in acoustically hostile environments. Motivated by humans ability to lipread, the visual component is considered to yield information that is not always present in the acoustic signal and enables improved accuracy over totally acoustic systems, especially in noisy environments. In this paper, we investigate the usefulness of visual information in speech recognition. We first present a method for automatically locating and extracting visual speech features from a talking person in color video sequences. We then develop a recognition engine to train and recognize sequences of visual parameters for the purpose of speech recognition. We particularly explore the impact of

A fricative consonant is a consonant that is made when you squeeze air through a small hole or gap in your mouth. For example, the gaps between your teeth can make fricative consonants; when these gaps are used, the fricatives are called sibilants. Some examples of sibilants in English are [s], [z], [ʃ], and [ʒ]. English has a fairly large number of fricatives, and it has both voiced and voiceless fricatives. Its voiceless fricatives are [s], [ʃ], [f], and [θ], and its voiced fricatives are [z], [ʒ], [v], and [ð] ...
Uvulars are consonants articulated with the back of the tongue against or near the uvula, that is, further back in the mouth than velar consonants. Uvulars may be stops, fricatives, nasals, trills, or approximants, though the IPA does not provide a separate symbol for the approximant, and the symbol for the voiced fricative is used instead. Uvular affricates can certainly be made but are rare: they occur in some southern High-German dialects, as well as in a few African and Native American languages. (Ejective uvular affricates occur as realizations of uvular stops in Lillooet, Kazakh and Georgian.) Uvular consonants are typically incompatible with advanced tongue root, and they often cause retraction of neighboring vowels. The uvular consonants identified by the International Phonetic Alphabet are: English has no uvular consonants, and they are unknown in the indigenous languages of Australia and the Pacific, though uvular consonants separate from velar consonants are believed to have existed ...

Physical changes induced in the spectral modulation sensors optically resonant structure by the physical parameter being measured cause microshifts of its reflectivity and transmission curves, and of the selected operating segment(s) thereof being used, as a function of the physical parameter being measured. The operating segments have a maximum length and a maximum microshift of less than about one resonance cycle in length for unambiguous output from the sensor. The input measuring light wavelength(s) are selected to fall within the operating segment(s) over the range of values of interest for the physical parameter being measured. The output light from the sensors optically resonant structure is spectrally modulated by the optically resonant structure as a function of the physical parameter being measured. The spectrally modulated output light is then converted into analog electrical measuring output signals by detection means. In one form, a single optical fiber carries both input light to and

There is already an abundance of SID tunes based on sheet music, in particular by J. S. Bach. The problem is that all those SID tunes are terrible. Apparently, people have merely typed in the notes from the sheet music. This leads to quantized timing (where e.g. every quarter note lasts exactly 500 milliseconds, always), and while quantized timing may be perfectly fine for modern genres, it simply wont do for classical music.. The goal is not to play the right notes in the right order; thats the starting point. Then you have to adjust the timing of every single note, listening and re-listening, making sure that it doesnt sound mechanical. You have to add movement, energy, and emphasis (which, on an organ, has to be implemented by varying the duration of the notes, and the pauses between them, because theres no dynamic response). You need fermatas and ornaments. You have to realize that some jumps cannot be performed unless the organist lifts his hand, and so on, and so forth.. This album is ...
