Exam 3 Study Questions Flashcards
The three major physical parameters of acoustics (define)
time- duration of a sound
frequency- number of vibratory cycles per second
intensity- amplitude of energy associated with a sound
Define spectrogram
a graphic representation of the physical parameters of acoustics (time, frequency, intensity)
Source of sound in the speech mechanism
larynx
Results from joining two or more words together in the creation of an utterance
connected speech
The process whereby phonemes take on the phonetic character of neighboring sounds
assimilation
Describe the two forms of assimilation
- Regressive assimilation: occurs when the identity of a phoneme is modified due to a phoneme following it
- Progressive assimilation: occurs when a phoneme’s identity changes as the result of a phoneme preceding it in time
Overlapping of articulators during speech production
coarticulation
Elimination of a phoneme during speech production due to particular phonetic contexts
elision
The addition of a phoneme to the production of a word
epenthesis
The transposition of sounds in a word; can occur as a result of a slip of the tongue, personal speaking style, dialectal variation, or a speech disorder
metathesis
The full weight of a vowel is not produced; common during rapid speech
vowel reduction
The 3 suprasegmentals aspects of speech production
stress, timing, intonation
A suprasegmental aspect of speech in which certain syllables, words, or phrases are given more emphasis, usually depending on the level of importance in the sentence.
stress
Differentiate between which words receive stress and which ones do not
Stressed- content words (more important), as well as new information
Non-stressed- function words (structural words), as well as given/inferred information
A suprasegmental aspect of speech in which the pitch of speech is modified, usually in order to convey mood or define the nature of the sentence (interrogative, command, etc)
intonation
