Quoted from PinballAir:I thought pascal had come out with a board for these?
It sounds like his board uses the chip.
Looks like there's some emulation code on github
https://github.com/mamedev/mame/blob/master/src/devices/sound/votrax.cpp
https://github.com/sealj553/votrax-speak
And recorded phonemes: https://github.com/sealj553/votrax-speak/tree/master/samples
Quoted from wiredoug:pascal sells it but i think you will find its a swemmer board (so you'll be able to get it locally in usa)
Oh, yep--looks like the image on pascal's site is just spun around so the board is upside down. I didn't catch that earlier.

Quoted from flooby47:Hi, I have read with interest the comments about the SC01A synthesizer chip. I used to use these in a talking scientific calculator I designed a number of years ago. I was amazed to hear this chip had been used in many diverse devices. I happen to be doing some work with DCC model trains and the possibility of adding speech and sounds cheaply. I found a synthesizer chip from Speakjet which sounds remarkably like the SC01A and currently available at around £28.
Unfortunately, the speechjet chip is not a drop-in replacement for the SC-01.
Someone did comment a while back about adapting a speechjet to emulate an SC-01, but I'm not sure if there was enough detail to actually build something:

Quoted from SMSavage32:I am the creator of the Speakjet. (Me and another guy named Jeff)
The reason that the Speakjet sounds similar to the Votrax is because we based the functionality of it on the Votrax.
However, we wanted the voice to be more understandable so we based the vocal data on Jeff's voice instead of the Votrax voice.
That being said, we can always change it.
So ... Is there any interest in making it a pin for pin drop in replacement for Votrax?
Is it worth taking the time to do?
Yes...the original sc-01 chip is now completely and entirely unavailable. All the known stockpiles are gone.
Having a new drop-in replacement would be great

Interesting video on q-bert voices, and a pre-announcement for an upcoming drop-in replacement SC-01 chip

Quoted from sparky672:Nothing about a release date or price
I did a cursory search when I first saw the video, but didn't find any announcements or discussions posted about it anywhere else.
