CSpeak and Cantarino
Yesterday’s surfing churned a couple of interesting links on the subject of speech synthesis and computer singing. I wasn’t really explicitly looking for this stuff, and can’t reconstruct what led me here, but I thought I’d archive this here. The first is a link to a formant based speech synthesizer in just 150 lines of code. The quality is, well, not amazing, but the code is simple enough to follow, and enabled me to gain a grasp of formant synthesis, at least, with a little explanation from Tom.
They have a video too!
Apparently this is derived from Cantarino, a project to do speech synthesis on the Arduino. It can sing too, and a bit better to my ear.
Both of these synthesizers have difficulty doing consonants in an intelligible way, but it is fascinating that such a simple technique can approach legible speech at all. Bookmarked for future tinkering.
