Ok, so there is something wrong in the pipe or the expectations of 
speex.  Your command piped wav format.  Logical.

But the man page says it will accept raw pcm, anything other than wav.  
So I tried substituting another format for wav.  I tried -f s8 and got a 
working result.  Not pretty but either my test file or my ffmpeg version 
is throwing errors.  (This laptop is running Hardy and some of the 
versions may be causing trouble)
 
For other formats, try $ ffmpeg -formats
