SpeakJet

2004-04-21 by djbrow54

With all this conversation on SpeakJet I thought I would share my
experience. I have one running interfaced to my PSIM. I don't have
the PC software installed yet and will do that this week so my
programming is somewhat limited. It currently just says "welcome".
I wrote a quick program to sample noise with my S&H and I use this
output to select and send a random allophone to the SpeakJet.

While messing around, it dawned on me that I could use the SpeakJet
output as the microphone input to my vocoder - it's a Roland SVC-350.
It came out pretty good!

Here's a link to an mp3 if you want to hear it. The first four
seconds are just the SpeakJet output. Then it goes into vocoder
mode. It's short but shows the possibilities. Enjoy!

I looked at the SpeakJet page, but based on comments I've read on
this list, I'm a bit confused. Can the SpeakJet be configured as a
VC module, or does it require a PC??

From what I've uncovered so far, this can be controlled by logic at
the "E" pins - either +5vdc or 0v - and/or TTL or single-wire serial
at pin 10. As a voltage control, I'm going to try feeding pulse
trains to the E pins (any number)at different rates to try and make
the device babble like an idiot. A hex schmitt trigger will give me
six simultaneous pulse outs. That's a good start. The TTL input
could probably work with a random pulse from, say, the '320 or '380
and others.

This is where I start to get a little, uh, unconventional. Yes the
voice and tone output is cute and all, but it seemed to me that this
output could be buffered and fed to another modules CV in. This, in
combination with the 3 digital outputs (which could be lagged or
mutated in other ways...) will provide hours of entertainment. Der
Speiler, indeed...

I would *highly* recommend against putting any signal into the TTL serial
input pin that isn't a serial interface from either a PC or microcontroller
that is actually sending *correct* communication to the chip. Reason
being... you will most likely really mess up your chip. Just don't do it.

The other input pins you referred to can be programmed for sounds and
triggered to play on both a high AND low signals. To get *true* analog
Voltage Control over the SpeakJet requires something like... say... well,
the only module in existence that will do it... the SynthModules PSIM-1.

Thanks for the info Brice!

I got my chip today, too. I'll have to play with my grandson for a
bit but then it's off the the lab for testing!

Hey Brice,
Can you give us an estimate of when your SpeakJet based module will
be available?

PSIM-1.

I'll take the ":-)" under consideration -- if it can be controlled
via CV, it can be controlled via CV :) I don't have a PS1M-1, or
have any plans to buy one, because I would not use a PC as a studio
computer. My question regarding the SpeakJet, is it possible to set
it up and use it without using a PC??

Re: [motm] Re: SpeakJet

2004-04-27 by Brice D. Hornback

I guess that would depend on whether or not you want it to do anything
besides cycle through the "demo" sounds. The SpeakJet itself cannot be
programmed via CV. The reason it works with the PSIM-1 is that the PSIM-1
converts CV to serial commands sent to the SpeakJet chip. Without the
PSIM-1... at some point, you must connect it to a PC. You can then use the
PhraseALator software to pre-program in some sounds. These could then be
triggered by CV (+5V max). That's what the additional inputs are for.
However, if you want to make it speak, sing, or use more than a few
preprogrammed sounds while connected to your synth, either a PC (which
doesn't have the capability to select allophones or sound effects via CV) or
the PSIM-1 (which does) is required.

Thabk you for your response. I hadn't realized the PSIM-1 worked
both ways. It looks like a great module, except that it's limited to
computers with serial ports running Windows. If there was a *nix
port that supported something like this

http://www.keyspan.com/products/usb/USA19HS/

then I might be able to run it off OS X.

>Without the PSIM-1... at some point, you must connect it to a PC.

That make sense. Although I imagine anyone who has a PSIM-1 already has a PC.
