Question

Which of the following vowels require that the mouth shift position during production of the sound? Select all that apply.

a.) /aw/
b.) /er/
c.) /oi/
d.) /ou/

Answer 1

The vowels require that the mouth shift position during production of the sound are a) / a w / and c) / o i / .

Step-by-step explanation:

a.) / a w / : This is a di-phth-ong, a complex vowel sound where the mouth shifts from a more open to a more closed position during production. It starts as / a / and glides into / w / .

b.) / e r / : This is not a vowel sound that requires a significant shift in mouth position. It is a rhotic vowel, often referred to as a s-ch-wa, and its production doesn't involve sub-stan-tial movement.

c.) / o i / : Similar to / a w / , / o i / is a di-phth-ong where the mouth shifts from a more open to a more closed position. It starts as / o / and glides into / i / .

d.) / o u / : Like / o i / , / o u / is a di-phth-ong, involving a shift from / o / to / u / .

Option A and C are the answers.
