Question

You have given your SLP intern the job of using PRAAT to determine the frequency values of a patient’s formants when pronouncing /ə/. The intern proudly reports back that F1 = 900 Hz, F2 = 1800 Hz, and F3 = 2700 Hz. Do you trust the intern’s numbers, or do you think the intern made a mistake? Explain your reasoning.

Answer 1

My dear learner, To take on this question, you need to have knowledge of the of the audibility range for the human sound. Normally a human can hear the sound frequency lying between 20 Hz to 20000 Hz.

Now come to data goven to me by the intern.

Yes, i'll trust the intern's number.

The reasons are as follows.

1. The number falls in between audible range.

2. 900Hz, 1800Hz, and 2700Hz all the frequencies falls on the lower side of the audible frequency range (20Hz to 20000Hz) which is expected from a patient.

Thankyou.
