Mmm... maybe just a missing step :-? The manual of "speexenc" describes itself as an "utility used to create Speex files from raw PCM or wave files" I mean, nothing about mp3 as input source so maybe is that you first have to convert the stream into PCM or WAV and then send it to "speexenc" (i.e., mp3 → pcm/wav → speex). I would look at "sox" as it seems very powerful for these kind of sound processing tasks.
