Ahh yes, sorry Stefan..Frank's RoboBox sweep circuit.  I hadn't seen the chip before and understand it all more now (should have clicked your link to the chip yesterday!).
5 oscillators with 4 waveforms including saw/square/sine/triangle...that there is enough for a small 18 pin device and that's beside it being able to talk as its main function!
I don't have the resources to get hold of one of these at the moment, but can see how useful they must be and will have a try with the SpeakJetAllophones wave file :biggrin:

Intelligibility of course is much improved with using the allophones, your posted .wav was readily understood. Do we call such a thing a 'great catch' ? lol, but that's what it seems to be.

I have a Speak&Spell, have built a square/saw/sine wave sound shaping device recently and so might set about seeing what can be done with the audio from the speech chip in that too. A fantastic online emulator for the unit is here: http://www.speaknspell.co.uk/
The TMS chips themselves went on to be improved and incorporated into digital answering machines etc.
