Next: Post-production parameters
These parameters include everything that influences the speech before it
is uttered. They are typically speaker-specific and include speaking
style, Lombard effect s, dialects , mental and physical
health , speech impairment , etc.
- Pitch or fundamental frequency
variability in this parameter is between male and female speakers,
the pitch of the women being roughly one octave higher than that of
men. Typical values are 200Hz for female speech and 100Hz for
male speech [Thielen (1992)]. The pitch of children is so
different that they are often treated as ``the third sex'' .
- Speaking rate
- This parameter can be measured in
words/minute for representative words, or as a ratio with respect to
the average of all speakers.
- Long term speech spectrum
- This is actually a set of
parameters; a representation can be the average energy in third
- Talking style
- This includes amplitude
(from whisper to shouting), fluency , clarity, etc. These are
generally no objective measures.
- Other characteristics, such as dialect ,
physical health , speech impairment .
