The discomfort sounds that infants make are usually

a. vowel-like
b. consonant-like
c. closed mouthed and consonant like.
d. open-mouthed and consonant-like.

Come on! By this time you should know that we will not simply GIVE you the answers.

What do you think the answer is?

To determine the answer to this question, we can analyze the options and consider the characteristics of the discomfort sounds that infants make.

a. Vowel-like: Vowels are produced with an open vocal tract, which typically results in a more relaxed and continuous sound. Discomfort sounds in infants are generally not vowel-like as they are not typically relaxed or continuous.

b. Consonant-like: Consonants are characterized by constriction or obstruction of airflow in the vocal tract. Discomfort sounds in infants often involve some level of constriction or obstruction, such as crying or whining, so this option seems plausible.

c. Closed mouthed and consonant-like: This option implies that the infant produces discomfort sounds with a closed mouth, which contradicts the common observation of infants crying or expressing discomfort with an open mouth. Therefore, this option is less likely.

d. Open-mouthed and consonant-like: This option aligns with the observation that infants often cry or make discomfort sounds with an open mouth, and these sounds typically involve some level of constriction or obstruction. Therefore, this option is more plausible.

By considering these factors, we can conclude that option d, "open-mouthed and consonant-like," is the most accurate description of the discomfort sounds that infants make.
