S/H Science poll everywhere review

The coordinated, physical movements of the vocal tract—lips, tongue, jaw, and velum— used to produce speech sounds (phonemes), are called

Articulatory gestures

The hypothesis that people perceive spoke words by identifying the vocal tract gestures with which they are pronounced, is called:

The motor theory of speech perception

Which influential publication by Chomsky and Halle proposed a model of binary phonology?

The sound pattern of English

The involuntary tendency of speakers to increase vocal effort when speaking in loud noise to enhance audibility

The Lombard effect

What is the science self-regulation machines?

Cybernetics

This is

A spectrum of complex tone

A vowel sound in which the tongue move from one vowel position to another within the same syllable, is a

Diphthong

Which format is most helpful in discriminating between vowels

F2

What could this be?

Wahoo

Which one is [aja] and which one is [iji]

[aja] is on the left and [iji] is on the right

This spectrogram is most likely

Jajajajaja

The production of [w] shows strong similarities with the production of

[u]

The production of [j] shows similarities with the production of

[i]

This spectrogram shows

One vowel- different pitches

Acoustically, what is the main difference between [i] and [u[

[i] has a high F2 while [u] has a low F2

The low resonance frequency of a bottle shaped cavity is known as

The Helmholtz effect

At the source level, the spectrum shows a fundamental with the highest amplitude and harmonics with decreasing amplitudes. In the vocal tract:

The energy gets rearranged and a different pattern emerges
