[Speex-dev] Best way to compress *many* .spx files

[Andras Kadinger]

Choose or invent a container format that has less overhead than the one 
you currently use, and that contains only elements necessary in your 
application.

Or, store multiple words (or maybe even the whole corpus) in the same 
Speex file, and then seek to the right position before playing back, and 
only play back as much as you need to (the word).

You aren't trying to make a speech synthesizer by any chance though?
