manipulation of voice onset time

[Daniela Sammler <sammler@xxxxxxxxxx>]

Hello,

I am looking for a good a way to manipulate voice onset time in real speech, for example to create a continuum from "bear" to "pear". 

So far, I spliced in aspiration noise between fricative and voice onset using PRAAT, but the result is not really satisfying.

Can anybody give advice?

Thank you very much!
Daniela
