| Question | Answer |
|---|---|
| Fo | Fundamental frequency |
| pitch | Fo |
| amplitude | loudness |
| Average fundamental frequency | the Fo measured in a particular speaking task, averaged over the speaking time of that task |
| Infants Fo | 350-500 Hz |
| Age 3-10 | 270-300 Hz |
| Age 20 Male | 120 HZ |
| Age 20 Female | 220 HZ |
| Frequency Variability | the range of Fos used in conversational speech measured either in terms of standard deviation of Fo or pitch sigma |
| pitch sigma | frequency variability in semitones rather than hertz |
| MPFR | Maximum phonational Frequency Range |
| the complete range of frequencies that an individual can generate | MPFR |
| 3 octaves | normal for young adults |
| average amplitude level | the overall level of amplitude during a speech task |
| amplitude variability | changes related to the speaker's mood, situation, feelings, and so on |
| Dynamic range | generated form the softest phonation that is not a whisper to the loudest shout measured in dB |
| VRP | a snapshot of vocal fold behavior at one moment in time |
| Voice Range Profile | a graph that plots maximum frequency against the dynamic range |
| diplophonia | occurs when each vocal fold vibrates at a slightly different rate, resulting in the perception of two pitches |
| Instrument that measures electrical resistance across the vocal folds | glottograph |
