Shall we take someone from Japan , deep Texas or even Wales ??
No I think we need to define a dynamic test method that simulates the human
voice.
It has to have the frequency components of speach mixed with the freqency
component
of the syllable frequency.
Another interesting thing is energy content of the different frequency
components .
The dynamic three tone test I mentioned in an earlier post is a step in that
direction, it just have to be defined and agreed upon..
