Subject: Re: No evidence of notes in raw speech F0 From: Martin Braun <nombraun(at)POST.NETLINK.SE> Date: Thu, 10 May 2001 14:19:11 +0200Thanks, Alain. Could you perhaps add in a further message what you meant by "raw speech F0" and "raw F0 contours". At what points in a sentence did you extract f0 ?
