Dear All
I feel on relatively safe ground when it comes to looking at features of
speech in terms of Hz, but recently it has been recommended to us that we
convert the Hz into semitones, or look specifically at semitones, in order
to carry out normalisation of data.
Can anyone advise us what is to be achieved by using semitones rather than
Hz, and / or suggest a means of normalising data? We are looking at F0 in
various populations of children (with all the problems that brings), and
comparing mean F0 and pitch range.
Many thanks
