Oric Speech Synthesizer + Cumulus/Microdisk
Re: Oric Speech Synthesizer + Cumulus/Microdisk
Finally managed to get all the parts, and it's working:
That being said, I did not manage to get it to work with the Cumulus, and it did not work with the expansion slot board (I've not used the +5v power of the board because I'm still missing the connectors, and even with the Microdisc to get it to work I had to seriously reduce the length of the cables.

Cool! The sound is bit tiny for integrated PC-speakers but everything is recognizable even for NON-French people .
Is there anything related to MIDI or it's just only kind of advertising:

Apparently they were also advertising a MIDI interface, but I don't remember having seen it.

Cool! Nice you get it working...

Re: Oric Speech Synthesizer + Cumulus/Microdisk
Cool! But wondering, does this speech synthesizer do only French? Or can you also use own coded data like the Texas Instruments PHP-1500 with Linear Predictive Coding encoding?
The TI reaches surprisingly high fidelity in a small data footprint on own voice recordings regardless the language with tooling to convert WAV to LPC.
Regardless of the anser, very cool project!

Well, it's based on the MEA8000, which works quite differently from the SPO256.
I'll try to see if I can get some cool sound out of it, ideally mixed with the rest of the Oric sound

Re: Oric Speech Synthesizer + Cumulus/Microdisk
The interesting part is if you can only use pre-dephined allophones, or can also use your own encoded allophones. You can do the latter with the TMS5220 chip the TI speech synthesizer uses.
Which is very interesting, as then you can not only use a predefined ‘voice’ but actually your own voice.
‘The LPC method of speech encoding reduces the speech data rate from approximately 100,000 bits/sec (raw digitized speech) to about 4800 bits/sec. The analyzer reduces this rate further (to 2000 buts/sec or less) by encoding each of the 20-bit speech parameters as 3 to 6-bit codes. These coded values select a 10-bit parameter from the parameter look-up ROM in the processor. Depending on the influence of the parameter on speech quality, between 8 and 64 possible values are stored in the Look-Up ROM for decoding and use in synthesis calculation.’
https://www.unige.ch/medecine/nouspikel/ti99/speech.htm
The link you have suggests that also the MEA800 can be used with your own allophone set:
‘The SP0256 contains predefined allophones (usually the -AL2 english allophone set), whilst the MEA8000 can be freely used with different allophone sets (english, french, other languages), different intonations (eg. raise the pitch to pronounce questions), or even as general purpose sound processor (ie. to produce music or sound effects)’
So that would imply that it indeed would be able to use it with your own recordings. Provided of course if there is any encoder for this chip available in any usable form.
For the TMS5220 chip there is this tool to do that:

I did a bit of optimization on the Synthor program:
From 2 minutes to 5 seconds should help with the testing

Can't read in detail what you did on Twitter, but in case you didn't already, don't forget to correct the Oric-1 bug ! That being said it produced funny sounds
BTW if you intend to understand the ASM code, I had just begun last March when I was seeking for the bug, and it was clearly inspired by what you can find in the book "Parole et micros" from Hervé Benoit and Michel Weissgerber (around page 49 from what I had written).

The bug:

(and also on the Oric.org page if I did my homework correctly )
I didn't dig much of the ASM as I re-read the basic and found the bug - so I gave up.
Here's the little I did:

Re: Oric Speech Synthesizer + Cumulus/Microdisk
Ha, ok, just the 255 thing
I actually read that, even answered it, but totally forgot
My plan is not to fix the basic stuff, but to make it possible to use the synthesizer in a more flexible way, like for example having some code that allows you to use HIRES graphics, because putting stuff in A000 is just not very practical.
