The recording of arterial sounds.

Difficult or abnormal voice production, the enunciation being too high, too loud, or too hard; weakness or hoarseness of voice.

1. To produce speech sounds; use the voice.
2. The utterance of sounds by means of the vocal folds; the basis of speech.

A reference to phonation.

An instrument where by a sound can be made to produce a visible record of itself; as an adjective, phonautographic.

1. A reference to various “sound” instruments; such as, an earphone or a telephone.
2. A speech sound identified as one of the variants of a phoneme.

1. The smallest unit of speech that distinguishes one utterance from another in all of the variations that it displays in the speech of a single person or particular dialect as the result of modifying influences (as neighboring sounds and stress).
2. The smallest sound unit which, in terms of phonetic sequences of sound, controls meaning.
3. The basic phonologic unit of a spoken language, identified in terms of a particular vowel or consonant.
4. An auditory hallucination of voices and spoken words.

Relating to the analysis of speech by phoneme identification.

A stethoscope for intensifying auscultatory sounds by means of a chest piece consisting of a shallow metal cup closed by a diaphragm; also, auscultoscope.

A phonendoscope combined with a screen on which movements of the heart or lungs can be observed during auscultation.

The common feature of sound occurring in a group of symbolic words.

1. Of or relating to spoken language or speech sounds; such as, phonetic developments in English since Chaucer’s time; and phonetic differences between ancient and modern Greek.
2. Of or relating to the science of phonetics.
2. Representing the sounds and other phenomena (as stress, pitch) of speech.
3. Constituting an alteration of the ordinary orthographic spelling that better represents its value in the spoken language, which employs only characters of the regular alphabet, and that is used in a context of conventionally spelled orthographies; for example, thru and nite are fairly common phonetic spellings.
4. Constituting those characters in some ancient writings (as Egyptian) that represent speech sounds as distinguished from such as are ideographic or pictorial
5. Representing speech sounds by means of symbols that have one value only as in this phonetic system, g always has the value of g in go, never of gin and gem.
6. Employing for speech sounds more than the minimum number of symbols necessary to represent the significant differences in a speaker’s speech; contrasted with phonemic.

A specialist in phonetics.

1. The study and systematic classification of the sounds made in spoken utterance as they are produced by the organs of speech and as they register on the ear and on instruments.
2. The practical application of this science to the understanding and speaking of languages.
3. The system of speech sounds of a language or group of languages; for example, “He reads Portuguese with some ease but finds its phonetics difficult.”
3. A written representation other than conventional spelling; such as, “The use of thru is considered a fair phonetics.”
4. The science of speech and of pronunciation; phonolgy.

Someone who advocates or uses phonetic spelling.

1. One who specializes in the study of disorders of spoken language and their management.
2. An expert or specialist in phoniatry.

1. The study of the voice and medical treatment of its disorders.
2. The analysis, assessment, and management of disorders of spoken language.

Medical treatment of the voice and its disorders.

A reference to sound or to the voice; especially, the aspects of the hearing of speech sounds.

1. The science of sound in general; acoustics.
2. The science of spoken sounds; phonetics.
3. The correlations between sound and symbol in an alphabetic writing system; used specificlly with reference to a method of teaching reading by associating letters or groups of letters with particular sounds in which the sound values of those individually written letters are identified and put together to form words.

An auditory sensation occurring when another sense is stimulated; also known as, auditory synesthesia (a sensation in one area from a stimulus applied to another part; such as, hearing a sound that may also produce the sensation of smell).

Recording and analysis of the audible frequency-intensity components of the bruit of turbulent arterial blood flow through a stenotic lesion.

Auscultation through a stethoscope of the sound heard when a vibrating tuning fork is placed against the chest. Auscultation is the process of listening for sounds within the body, usually sounds of thoracic or abdominal viscera, to detect an abnormality or to check for fetal heart sounds.

Having the property of reflecting sound, or producing an echo; relating to the reflexion of sound, cataphonic.

A graphic record of the heart sounds made by means of a phonocardiograph; abbreviated as PCG.

An instrument, utilizing microphones, amplifiers, and filters, for graphically recording heart sounds and murmurs, that are displayed on an oscilloscope or analog tracing.

1. Recording of the heart sounds with a phonocardiograph.
2. The science of interpreting phonocardiograms.

A catheter with a microphone at its tip for recording heart sounds and murmurs within the heart and great vessels.

The use of a phonocatheter for the detection of sounds produced by the circulatory system. An intracardiac phonocatheterization, for example, consists of the passage of a phonocatheter into a chamber of the heart for the detection of sounds as an aid in the diagnosis of cardiac defects.
