Can't be.  The raw payload for iLBC is 13kbps or so, for speex with it's 
default settings is 12kbps.

You really shouldn't evaluate a voice codec with music; they are not 
designed for that.  (if your song is only voice, then it might be OK).

Look at the implementation:  Each codec sets their minumum frame size 
(really, it's their "natural" size), and the library has it's own 
minimum.  We use the smallest multiple of the codec minumum that is 
equal to of greater than the library minumum.

The codec mins are 160 samples for everything 'cept iLBC, where it's 240.
Here's a "table" of what you'd get.

CodecMin	LibMin		Frame Size
160		160		160
240		160		240
160		240		320
240		240		240
160		320		320
240		320		480
160		480		480
240		480		480
