5. If you and a friend both say “ah” with the same fundamental frequency, will you still be able to distinguish between your voices? Why? 4 points
6. If a person has a hearing loss in the high frequencies, they may hear fundamental frequency but have difficulty distinguishing different people’s voices. Why? 4 points
7.
Give two reasons

9. Using PRAAT measure jitter, shimmer, and the Mean Harmonics to Noise Ratio of your voice. You will record your sample like you did in the past and then add a few additional analyses.
Once you record and save your waveform. Click on
View and Edit.
Highlight your sample using the cursor. Click on
Pulses.
Then click on
Show Pulses. Once your pulses are highlighted you can click on
Voice Report which is under Pulses.
You will see
a lot
of data. I only want you to record the numbers indicated below. 12 points

S/Z ratio
: 5 points each – 10 total
A.
Perform a s/z ratio assessment on yourself. Complete three trials and take the longest duration /s/ and the longest /z/. Divide your /s/ duration by the duration for /z/ to determine the s/z ratio. Report both the durations for /s/ and /z/ as well as the ratio. Do each of the measures fall within normal limits?
B.
Perform a s/z ratio assessment on someone other than yourself using the above method. Do each of the measures fall within normal limits? Change the pitch of your s and z. What happens when you change the pitch?
Phonation: -
5 points
C.
Use a stopwatch to measure how long you phonate. Take a deep breath and phonate a vowel (your choice of vowel) for as long as you can. Perform two more trials to see if your maximum phonation time improves with practice. What other factors do you think could influence maximum phonation time? Try a different vowel or a very low or high-pitch vowel to see if changes in pitch alter your results. What did you find??
