// I call EncodeSpeech() with a byte array containing PCM-encoded audio data that I get from the 
// microphone (with len being the number of encoded bytes in the buffer, in case this is the 
// last chunk and the buffer is only partially filled).  
// In my app I send the returned byte array to a service for processing - hence I prefix the 
// encoded Speex data it with length information.
// The reason that I prefix the data with both the original PCM buffer size as well as the 
// the size of the encoded chunk is that the DECODER needs to know the original buffer size, 
// otherwise it does not decode properly.  Of course the size of the encoded chunk is to "frame"
// the chunks for the service, which may read multiple chunks off a stream.
