Cheetah Sweet Talker doc/test?

[system11]

Does anyone have any kind of instructions or the Chatbox tape which came with the Sweet Talker?

I have one here, it hums when switched on but I have no idea how to communicate with it, zero documentation that I could find out there.

No worries buddy I have said doo-dah and will post instructions a bit later when I get home.

The initial hum is normal by the way and if you find the thing is too loud for a small room ( internal amp set too high ) I can show you quick fix to cure it.

Forgot to ask is this for the Spectrum or ZX81?

For the Spectrum The instructions are attached ...


A video for same..

For the ZX81.

Make first line a REM then poke the following values into it.

16514---62
16515--- XX ( The allophone to be used )
16516---211
16517---7
16518---201

To use store your allophones somewhere poke them one at a time to 16515, RND USR 16514 rinse and repeat.

If used in a FOR NEXT loop, then a PAUSE or FOR NEXT delay of about 3 or 4 should also be added or the speech is a bit unintelligible.

ZX81 - I'd only managed to find Spectrum or BBC instructions - thanks I'll try the above!

[system11]

I've managed to make some horrendous noises, this is a good start. Is there anywhere that would have the Chatbox tape image? I've actually been surprised by how much of this stuff isn't archived anywhere.

What are the values in the POKE other than the allophone?

I'm trying to make it say "ZX" but I can't get anything that remotely sounds like "zed" yet out of it. I thought that should be something like 43 7 21 but it's coming up with something like "oay" when I try that.

I managed to get it to say "Cheetah" using the ones in the Spectrum program - actually even in fast mode the pause isn't needed!

Code: Select all

 10 REM CHEETAH SPEECH TEST
 20 POKE 16514,62
 30 POKE 16516,211
 40 POKE 16517,7
 50 POKE 16518,201
 60 FOR N=1 TO 16 STEP 3
 70 LET J=VAL "50 19 13 15 15  0"(N TO N+1)
 80 POKE 16515,J
 90 RAND USR 16514
100 NEXT N

You poke just the allophone value to 16515 then call 16514 to sound it. You do have to have a pause of at least three in value between calls or it sounds crap. I have the tape and will try and post a recording of it for you.

A typical program might be...1 REM xxxxxxxx ( the code previously posted )

10 LET L = ( THE ADDRESS WHERE THE ALLOPHONES ARE STORED )

20 F = 1 TO ( HOWEVER MANY ALLOPHONES THERE ARE )

30 POKE 16515, PEEK L

40 RND USR 16514

50 PAUSE 3

60 LET L = L + 1

70 NEXT F

I think we cross posted there

Code: Select all

ZX81 Sweet Talker m/c program
Address - Dec -  hex - mnemonic 
16514 ---  62 = 0x3E = LD A,XX (put the value XX into the Accumulator register)
16515 ---  XX =   XX = the XX for the above (the allophone to be used )
16516 --- 211 = 0xD3 = OUT (n),A (output the value in the Accumulator to port n)
16517 ----  7 = 0x07 = the n for the above, in other words the port address
16518 --- 201 = 0xC9 = RET (RETURN to BASIC)

Done manually on my phone, so if any errors, I blame autocorrect/autosuggestion or my fingers...

So it takes the value stored at address 16515 and sends it out on I/O port 7 to the Sweet Talker hardware
