Physiological and Acoustic Phonetics

What is Broad Phonetic Transcription?

• The transcription of allophones by putting them in brackets

  Ex: [f]

• The use of IPA symbols to transcribe them using enclosed slashes

  Ex: /f/

• fThe transcription of allophones by using diacritic markers

  Ex: ä

• The use of diacritical markers to transcribe phonemes by placing them in enclosed brackets

  Ex: (/f/)

Two properties of a medium that affect sound transmission are:

• Amplitude and Intensity

• Pressure and Force

• Compression and Rarefaction

• Density and Elasticity

The Coda is:

• The nucleus of the syllabus

• The initial sound in a syllable

• Open syllables

• The consonant at the end of the syllable

The back and forth movement of air particles due to a vibrating object is called:

• Amplitude

• Oscillation

• Velocity

• Displacement

A sinusoidal sound wave:

• Is the result of simple harmonic motion

• Has multiple frequencies

• Has multiple peaks and valleys

• Is asymmetrical

During speech production, vowels:

• May stand alone

• Are unvoiced

• Require interrupted airflow

• Require a lowered velum

Stressed syllables are often:

• Softer in intensity

• Shorter in duration

• Longer and higher in pitch

• Lower in pitch

An octave is:

• The amount of displacement of air molecules

• The amount of time between cycles

• The interval between two frequencies

• A measure of intesity

A bilabial voiced glide that is anterior and continuous is:

• /r/

• /w/

• /j/

• /t/

/r/ and /l/ are both kinds of ______ sounds

• Glides

• Rhotics

• Laterals

• Liquids
