You can feed festival an XML file that describes the pitch, duration and voicing of a syllable. Example: http://www.gjcp.net/~gordonjcp/mp3s/robots.mp3 As Julien said, the other option would be to use a vocoder, which applies a filter shaped like the frequency response of the modulation to a carrier signal. There is a LADSPA floating about for that, but it's a bit buggy. I modified it: http://www.nekosynth.co.uk/browser/wip/vocoder/trunk It really needs the lower band replaced with a lowpass filter and the highest band replaced with a highpass filter. It sounds like this (carrier produced by nekostring): http://www.gjcp.net/~gordonjcp/mp3s/kelly.mp3 Ideally you want a bright buzzy carrier with lots of harmonics to filter. Like, uh, a string ensemble...
