Another speech demo. The speech chip used in the TI-99/4A speech synthesizer was designed around 1976-1977. A trimmed down version was used in TI's famous Speak and Spell toy.

Here, I took a section of a pod-cast from www.retrobits.com (great site!) and downsampled to 8khz mono, then processed in QBOX.

You can see the assembly source code if you change the view to full screen ;-)

The original WAV file was 283KB, the speech data, after processing, was 4.6KB :-)

NOTE: What you are hearing here is an EMULATOR, not the real thing. It sounds better on the real thing :-)

Also, it's much more readble if you view this video in High Quality.

Hope you retro fans like this vid ;-)
