Phonetics and Acoustics: The Speech Science Foundation

The “typical” speaker of Standard American English would produce the word emancipation as

• ɪmansəpeɪʃn

• ímansəpelʃən

• imænspeɪʃən

• ɪmʌnsʌpeɪʃn

The /r/ and /l/ sounds may both be categorized as

• Rhotics

• Glides

• Laterals

• Liquids

A semivowel that can be categorized as a voiced bilabial glide that is + anterior and + continuant is the

• /j/

• /w/

• /ʃ/

• /r/

The term coarticulation refers to

• Speech sounds being modified due to the influence of adjacent sounds to the point that there are perceptible changes in sounds

• The extent to which vocal tract configuration changes shape during the production of consonants and vowels in running speech

• The influence of one phoneme on another in production and perception wherein two different articulators move simultaneously to produce two different speech sounds

• The influence of various syllables on one another when a client recites a phonetically balanced list of word

Broad phonemic transcription involves

• The use of IPA symbols to transcribe phonemes by enclosing them within slash marks (e.g., /f/)

• The use of diacritical markers to transcribe phonemes by enclosing them within slash marks (e.g., /f/)

• The transcription of allophones by placing them within brackets (e.g., [f])

• The transcription of allophones by the use of diacritical markers

If a speaker said “I just love’em and leave’em,” the phrase “leave’em” would be transcribed as

• [liv əm]

• [lev] [em]

• /liv əhm/

• /liv m/

The two properties of a medium that affect sound transmission are ________ and ________.

• mass; elasticity

• temperature; color

• mass; volume

• pressure; humidity

A sinusoidal wave is a sound wave

• That is asymmetrical

• With multiple peaks and valleys

• With multiple frequencies

• That is a result of simple harmonic motion

A natural frequency is a frequency

• With which a source of sound vibrates naturally

• That is unrelated to the mass and stiffens of the vibrating body

• That is the center frequency of a format

• That refers to the simple harmonic motion

An octave is

• The amount of molecular displacement per unit of time

• The amount of time between cycles

• An indication of the interval between two frequencies

• A measure of the magnitude (intensity strength) of the sound signal
