Just buy a raspberry pi, load a voice recording of your own for simple commands or any of many speech synthesis modules. Python away to make it say anything you want. Code is much easier, faster, cheaper than solder.

I know you said you don't need any other versions of the SP0256 but I might have one that you're missing. I have an SP0256A-053 and I can't find a single mention of it anywhere online. I'm not very attached to it if you're interested.
 
Othe SP0-256 ??
Yes interested !
My email address is <snip>
Send me a mailing address and I'll send it to you gratis. :) I hope you do something with it. It's been sitting in my parts bin for years.

Wow... talk about harking back to the 'good old days'.... I actually still have an SP0256-017 and the SPR016 ROM that came with it. Looking forward to making a project with this.
 
HI George,
Attached are the first page of the manual, the introduction page, and the first page of the bill of materials.
You are right, is not a "digitalker", but the TMS5220 voice synthesis processor, with TMS6100 voice synthesis memory.
I will take a picture of the circuit board tonight, and note which ones are the UV eproms.
Hi Eric,

I found the manual for the TI Speech Education Module in the TI Archive at Southern Methodist University.

I’m fascinated by this and I wonder if you’ve got your board up and running?

I’m in the middle of typing in all the Forth source code. I’ll be running it on TI-99/4A or my own build of a TMS99105 computer. Adding a TMS5220C because those are the plentifully available chips.

I have a lot of history with TI chips and LPC. My father worked in the TI speech lab in Lubbock, TX.

I don’t have any special hardware, except the consumer products. (Though on my 4A I have the modern peripherals like TIPI and speech in the PBOX.)

Would love to find a Speech Education Module, or the TM990/306 board that was released in 1981 when the 5100/6100 became commercially available.

Stuart Conner’s website has a wealth of information on TI modules such as his portable Speech Coding Lab unit (used for vocabulary in UK subway announcements!)
 
Hello,
Very interesting !
Do you have a link to download the documentation ?
François
If you mean the TI Speech Education Module, no I don’t have a link. I don’t have permission to share documents from the library. If Eric were to scan his copy, that would be different…
 
I have tried to connect to library available on internet but i can't find this documentation.
Can somebody share ?
Sorry, I meant that I visited the library in person.

I just bought a Speech Education Module with VM61002 phrase ROM. There are 4 standard 2532 EPROMs and 2 2K SRAM.

The PCB accommodates one more VSM, a 2K RAM, 4 2532s.

working on powering it up now.
 
Hello,

Can you dump the 4 eproms and share contents please ?

Have you a schematics? / Bom ?
Yes, I will dump the 4x 2532. I created a tiny PCB to adapt 2532 to 2764 socket (finally) and I'll have them dumped in a week. I'm also recovering the 2532 from the DS990/1 I/O Interface board (a TMS9981 controller.)

As for the schematic, I don't have a paper copy. I'd have to fill out the TI permission form to share the one in the TI Archive. But yes, the manual has full schematics, BOM, and source code in Forth and TMS7000 assembly.

The Speech Education Module has analog out on a phono mic jack. It doesn't have input. The TMS5220 output goes through a 4-stage re-emphasis filter. It is mixed with the output of a DAC08 (parallel 8-bit input) whose function is to play raw samples. It does not have analog input, nor the CPU power to analyze speech.

(In analysis of analog speech data, a de-emphasis filter is first used to attenuate low frequencies. The synthesizer output is supposed to have a re-emphasis filter. In the case of Speak and Spell, the cheap speaker *was* the transfer function the synthesizer output was designed for--it attenuates high frequencies.)
