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.

One thought on “CSpeak and Cantarino”

  1. On that first one, I thought “hey, this is actually pretty good!”, then I closed my eyes and realized that even knowing the tune there was a lot that reading the words was doing to fill in how I was hearing the audio.

    Relatedly, I just listened to Coverville Episode #726 which featured a Japanese “vocaloid” performance of an English song that I was pretty impressed by, at least from a technical standpoint.
