Speech Synthesis?

[Christoph CP]

Hello,

i have a question: is it possible to generate an 8 Bit Speech Synthesis Engine. 

Like these old Speech Synthesizers from TI and Spectrum?

Greetings

Hi Christoph,

Like many 80s peripherals, the Speech Synthesizer chips used, the SP0256-AL2 used in the Currah Microspeech and the TMS5220 used in Speak And Spell are no longer available:

There is also the SpeechJet speech synthesizer available from SparkFun:

At $25 for the bare chip it's fairly expensive, but there are some arduino projects which use it. I imagine the computation required should be possible with a modern DIL microcontroller and the source code for a TMS5220 emulator can be found from the MAME source code:

https://github.com/mamedev/mame/blob/master/src/emu/sound/tms5220.c

Hope this helps!

-cheers from Julz

I have actually got a lot of the SPO256-AL2 and associated Microspeech chips!

I mean if this is possible on the FIGnition?

Hi Christophe,

I think Julz is saying it should be possible in theory when he says: "I imagine the computation required should be possible with a modern DIL microcontroller and the source code for a TMS5220 emulator can be found from the MAME source code". He just stopped short of saying the FIGnition explicitly. Possibly for fear of the temptation to start working on it himself ;)

Apologies for the extraneous 'e' on your name, there.

Hi guys,

I was thinking it'd make a good Shield :-)
