Software capable of recognizing dictation and transcribing the spoken words into written text.

Communication through a system of conventional vocal symbols.

Behaviors associated with the giving of assistance or aid to individuals.

The process whereby an utterance is decoded into a representation in terms of linguistic units (sequences of phonetic segments which combine to form lexical and grammatical morphemes).

Sequential operating programs and data which instruct the functioning of a digital computer.

In INFORMATION RETRIEVAL, machine-sensing or identification of visible patterns (shapes, forms, and configurations). (Harrod's Librarians' Glossary, 7th ed)

A test to determine the lowest sound intensity level at which fifty percent or more of the spondaic test words (words of two syllables having equal stress) are repeated correctly.

Measurement of the ability to hear speech under various conditions of intensity and noise interference using sound-field as well as earphones and bone oscillators.

Ability to make speech sounds that are recognizable.

The acoustic aspects of speech in terms of frequency, intensity, and time.

Electronic hearing devices typically used for patients with normal outer and middle ear function, but defective inner ear function. In the COCHLEA, the hair cells (HAIR CELLS, VESTIBULAR) may be absent or damaged but there are residual nerve fibers. The device electrically stimulates the COCHLEAR NERVE to create sound sensation.

Tests of the ability to hear and understand speech as determined by scoring the number of words in a word list repeated correctly.

Any sound which is unwanted or interferes with HEARING other sounds.

Wearable sound-amplifying devices that are intended to compensate for impaired hearing. These generic devices include air-conduction hearing aids and bone-conduction hearing aids. (UMDNS, 1999)

The interference of one perceptual stimulus with another causing a decrease or lessening in perceptual effectiveness.

The science or study of speech sounds and their production, transmission, and reception, and their analysis, classification, and transcription. (Random House Unabridged Dictionary, 2d ed)

Acquired or developmental conditions marked by an impaired ability to comprehend or generate spoken forms of language.

Measurement of parameters of the speech product such as vocal tone, loudness, pitch, voice quality, articulation, resonance, phonation, phonetic structure and prosody.

Procedures for correcting HEARING DISORDERS.

The sounds produced by humans by the passage of air through the LARYNX and over the VOCAL CORDS, and then modified by the resonance organs, the NASOPHARYNX, and the MOUTH.

The audibility limit of discriminating sound intensity and pitch.

The graphic registration of the frequency and intensity of sounds, such as speech, infant crying, and animal vocalizations.

The analysis of a critical number of sensory stimuli or facts (the pattern) by physiological processes such as vision (PATTERN RECOGNITION, VISUAL), touch, or hearing.

Surgical insertion of an electronic hearing device (COCHLEAR IMPLANTS) with electrodes to the COCHLEAR NERVE in the inner ear to create sound sensation in patients with residual nerve fibers.

Use of sound to elicit a response in the nervous system.

The knowledge or perception that someone or something present has been previously encountered.

Information systems, usually computer-assisted, designed to store, manipulate, and retrieve information for planning, organizing, directing, and controlling administrative activities associated with the provision and utilization of radiology services and facilities.

Treatment for individuals with speech defects and disorders that involves counseling and use of various exercises and aids to help the development of new speech habits.

Persons with any degree of loss of hearing that has an impact on their activities of daily living or that requires special assistance or intervention.
