Ogg vorbis is for music. The vorbis faq recommends "speex" for speech:

Speex can be embedded in Ogg:

Hi Jim --
Squeak has some very low bitrate codecs just for speech that we did
years ago that are much more compressed than mp3 (by a lot). I'm
wondering whether ogg has something similar and special just for
human voice (non-singing)? This could make a big difference wrt the
limited storage of XO.
Cheers,
Alan
