Practice question · Sort into groups
Sort each property by whether it belongs to the SOURCE or to the FILTER.
Groups: Source · Filter
- Changes when the folds are tensed
- Heard as vowel quality
- Heard as pitch
- Changes when the tongue moves
- Resonances determined by tract shape
- Rate of vocal fold vibration
Hints
- One is produced at the larynx, the other above it.
- Anything about the tongue belongs to the filter.
Show the answer
Source: Rate of vocal fold vibration, Heard as pitch, Changes when the folds are tensed
Filter: Resonances determined by tract shape, Heard as vowel quality, Changes when the tongue moves
Why
Keeping the two columns apart resolves most confusions in this lesson, F0 against F1 in particular. They are produced by different structures, vary independently, and are heard as different things.
