Hi Andrew, 'can't anser the technical question exactly, but you might want
to look at the MP3 file's sample and bit rate. Except for very high quality
voices, there's no point sampling at higher than 16KHZ, and possibly lower.
The highest sample rate of any speech synth that I've come across is 22KHZ.
Also is it generating stereo files, if so, then that's pointless, as all
speech synths are essentially mono. Both these measures will substancially
reduce the size of the files.

hi guys,

It looks like Gens has already put some new voice files up on the wiki, so I
don't need to worry.
Btw, can anyone tell me just how critical the 1.6 mb limit on the voice file
size is? With the itroduction of gen2 language support, I am routinely
generating voice files larger than this. In fact, they are closer to2mb in
size. However, I am not having any problems using the files on my Iriver
H340. Is this limit mainly needed for the Archos units?
