• Spoken to infants

Question 2

Question 5

When the features of a sound spread to neighbouring sounds.
It tells us how far ahead speech is planned.
CV syllable coarticulation develops as children develop fine motor speech skills.

When a segment affects the sound following it

Question 8

How does F2 relate to coarticulation?

Answer 8

F2 locus equations can capture overall patterns.
Assessed using xray microbeam data.

Question 9

Are formant frequency transitions slower in diphthongs?

Answer 9

Yes

Question 10

How does frequency changes affect coarticulation?

Answer 10

BIG changes = less coarticulation

Small/NO changes = high degree of coarticulation due to gestural overlap

Question 11

Formant frequency transitions cues?

Answer 11

Fast in CV syllables starting with a plosive.

Slower in CVs when consonant is a glide e.g /wi/.
