See the SPEEX_SET_VBR and SPEEX_SET_VBR_QUALITY options. But be aware
that unless you're aggregating many VoIP calls on the same link, there's
little use for VBR in VoIP.

You cannot create RTP packets from speexenc. If you only want to see the
length, you can either use the -V option, or encode to Ogg and use
oggzdump to inspect packets.
