David,

You would keep the value.  It is already possible to make relative changes in percentage terms.  It is the author's responsibility to specify the relative change in the terms desired.

Subject: Relative Pitch change in Hz or st through voice change



quote:
"...
Relative changes in prosodic parameters should be carried across voice 
changes. However, different voices have different natural defaults for 
pitch, speaking rate, etc. because they represent different 
personalities, so absolute values of the prosodic parameters may vary 
across changes in the voice.

How the syntesis processor have to deal with relative pitch change in 
Hertz or in semitone?

/******

For example, you have a male voice (baseline pitch of : +/- 100Hz) with 

a relative change of 10Hz. You change the voice in a female one 
(baseline pitch : +/- 180Hz) and you keep the relative pitch change:

male    :  100 -> 110 Hz : +10.0%
female  :  180 -> 190 Hz : + 5.5%

the proportion of your relative pitch change in Hertz have been
corrupted!

How the synthesis processor have to deal with relative change in Hz or 
st through a voice change: keep the value or keep the proportion?


Yours,
David Descamps
