Speech synthesis with the Orangutan SV-328

Posted by Kevin on 2 October 2013

Forum user Jim Remington has been working on getting the Talkie speech synthesis library to run on an Orangutan robot controller. The Talkie library, written by Peter Knight for the Arduino, has its roots in a Texas Instruments speech synthesis system that dates from the 1970s and was used in the Speak & Spell educational toy.

When we read about what Jim was doing on the Pololu Forum, we wanted to try it ourselves. We modified Jim’s Orangutan LV-168 code to work on the Orangutan SV-328, and we discovered that the Orangutan’s motor driver could be used as an improvised audio amplifier. This video demonstrates the result:

(Yes, those numbers are a little implausible, but they’re a good way to show off Jim’s number-to-speech routine.)

Our version of Jim’s demo, converted to an Atmel Studio 6 project for the Orangutan SV-328, can be found in this post. To read more about Jim’s work and download his code, see his forum topic.
