Free glitchy speech synth
« on: March 18, 2008, 11:37:58 PM »

Released under the WTFPL, with the proviso that if you use bits of it in a commercial track I'd like you to send me a copy.
It's the contents of a firmware ROM fed through a software LPC10 codec similar to the ones used in a Speak'n'Spell.

Hi, that sounds interesting, on what platform (mircocontroller?) did you implement the LPC ?

It's running on a PC, although I'm working on porting it to an Atmel microcontroller - bent speak'n'spell noises without the broken speak'n'spells!

I've thought about implementing a LPC in a PIC, but I suspect it has not enough performance to do that.
In case floating math is need, or not?

It can't need *much* - there wasn't a lot inside the chips used in the original Speak'n'Spell.  Given the technology of the day, I reckon it must be pretty crude...

I've found some emulation source code for the sp0256 speech chip
http://mamedev.org/source/src/emu/sound/sp0256.c.html
and the design manual for the speak&speel soundchip
