liboggz (and its tools) supports Speex in Ogg.
speexenc encodes Speex from PCM (can mux in ogg).
speexdec decodes Speex (can probably do from ogg)
Gstreamer has Speex elements.

So a combination of speexenc and oggz-merge might do.
For realtime (as opposed to plain files), I'm not sure if speexenc can
be used, I haven't checked.
