IE doesn't support Web Audio either. The project I linked above does contain a Flash shim for IE, which you may find helpful. Any proper realtime audio stack (which ogv.js is not: it targets moderate latency streaming) is going to require a jitter buffer to deal with network/processing latency variation. Writing one is a non-trivial exercise (though not impossibly so). In any case, I'd recommend using Opus (the audio codec used by WebRTC) over Speex.
