Practice question · Multiple choice
A speaker raises their pitch while continuing to say the same vowel. Why do the formants stay roughly where they were?
Hints
- The source and the filter are independent.
- Pitch is the rate of fold vibration; vowel quality is the shape of the tube.
Show the answer
A. F0 rises while the formants stay roughly where they were
Why
F0 rises and the formants do not follow. The source and filter are independent, which is the whole content of the model, and the everyday proof is that you can sing a scale on a single vowel without the vowel changing.
