Title: AmJet - anyone interested in a low-cost speech synthesizer?
Post by: LambdaMikel on 18:58, 31 May 18
I am musing on the idea of making a new low-cost speech synthesizer for the CPC. One that people can afford (LambdaSpeak is still too expensive, due to the 39 $ click board).

It will be 45 $ device, consisting of

- an Atmega 328p
- the 25 $ SpeakJet chip
- a flipflop
- a bus driver
- an op-amp

(all through hole). It will be SSA-1 and DKtronics compatible, and have a SpeakJet mode as well.

Maybe it will also have AMDrum emulation.

It will be called "AmJet"


Would there be any interest in such a device?

Good idea! However, I really hope that you still release the LambdaSpeak device.  :)

In a sense, it is released - everybody what wants one can build it themselves:

So what would be the difference with the Lambdaspeak ?

Different speech chip. Speakjet - cool video here (not mine!)

Sounds completely robotic. But cool in itself!
It is only 25 $.

Will it need a different RSX extension?

Not quite sure yet. For sure, there are major differences with DecTalk. Does it have different voices, spanish, english mode? Probably not.
These commands will just be ignored. DecTalk mode - not applicable.
Volume, speed? I will see. Haven't started yet looking at the chip in detail.

sounds interesting :)

Could be a perfect Dalek emulator!  ;D

Yes, it's accent sounds quite British indeed - almost like a BBC speaker  :laugh:
And, what's even better, you'll get one for free if you do the RSX port of course  ;)

Haha! Yes indeed! The RSX Extension shouldn't be a problem at all. Since I already got the LS 1.5 I don't need the other one - even if I really like the sound of it. More thinking about getting a robot (see other Thread ZX as Dalek controller!  :) ).


EDIT: Hmm.... maybe it's to early for that... However it could be an nice idea to do a poll to ask which Speech Synthy people would like to buy? Could make it more easy to order PCB's (Bryce I remember offered help to do a series of them?!?). I'm just looking forward!  :)

Right, I am leaving all potential future / follow-up action to Bryce if and when he finds the time. For me, LambdaSpeak is done. Maybe I will sell a couple of kits (PCB + parts) on Ebay with programmed chips, but not many. PCB assembly services are too expensive for small batches, the potential sales number too small, and I don't have enough time to solder them manually.
