Term
Articulation
Definition
The production of sounds-namely, vowels, diphthongs, and consonants.
Term
Assimilation
Definition
The influence of one speech sound on another.
Term
Breathiness
Definition
A vocal quality characterized by the release of excessive breath because the vocal folds are not brought closely enough together during phonation; also caused by lack of breath support.
Term
Diaphragm
Definition
A double, dome-shaped muscle of respiration that forms the floor of the thorax (chest) and the ceiling of the abdomen. The most important muscle used in abdominal breathing.
Term
Diction
Definition
The choice and use of words. An individual should have both written and oral diction. A secondary definition of diction involves the distinctness of speech.
Term
Glottal shock
Definition
Also called stop. A vocal quality in which the vocal folds are forced apart by breath that has been held back, resulting in an explosion of sound, usually on an initial vowel or diphthong.
Term
Glottis
Definition
The space between the true vocal folds.
Term
Hard palate
Definition
The first third of the roof of the mouth, composed of bone and membrane
Term
Intercostal muscles
Definition
Muscles located between the ribs that, when contracted, elevate the rib cage. These are important muscles in diaphragmatic breathing
Term
IPA
Definition
An alphabet of visual symbols that represent sounds.
Term
Larynx
Definition
Voice box. Top of the trachea. Protects vocal folds.
Term
Modal Pitch
Definition
habitual pitch. the pitch levels you use most frequentally.
Term
Open Throat
Definition
Optimal pharyngeal resonance; a relaxed throat that produces a relaxed sound.
Term
Optimum pitch
Definition
The best sound for your voice with least effort.
Term
Oral resonance
Definition
An amplification and modification of the fundamental tone in the mouth.
Term
Pharyngeal Resonance
Definition
An amplification and modification of the fundamental tone in the throat.
Term
Pharynx
Definition
The throat cavity located between the esophagus and the opening to the nasal cavity; the size of this cavity can be adjusted. Also called the throat.
Term
Phonation
Definition
The sound made by the vibration of the vocal folds.
Term
Pitch
Definition
A factor of sound related to frequency, or the number of vibrations per unit of time. Perception of highs and lows of sound.
Term
Quality
Definition
A factor of sound determined by the complexity of vibrations per unit of time. The subjective interpretation of sound determined by the complexity of the vibration; the amplification of the partials-- overtones that individualize a voice.
Term
Rate
Definition
Amount of time that is given to a speech utterance as well as silences.
