speech synthesis

GinSing contains complete support for synthesized speech for the Sounding IC. The Soundgin IC has exceptional voice synthesis, allowing on-the-fly changes to pitch (and musical note), speed and volume. For example, you may use the dynamic pitch control in response to a temperator sensor on the Arduino, as well as singing the spoken phrase from "Its Cold" to "Its 100 degrees!" at various singing notes.

The method for producing speech involves creating a phrase, which is a string of allphones, inline optional inflections, and inline optional timing information that is executed using the speak() command. A phrase can contain just a single word or an entire orration. Allophones are phonemes that are blended smoothly over time to create natural sound speech synthesis. Inflections produce variation in pitch, speed, and volume that can be embedded into a phrase to effect a single allophone. You can also dynamically control pitch, volume, and speed in general with additional function calls. Here is the code that that makes the announcement on our website:

  GSAllophone phrase[] = {_IE,_A,_M,_BENDDN ,_J,_I ,_NE ,_SE ,_PITCHDN,_I ,_PITCHDN,_NGE,_PA0,_ENDPHRASE };

  speak (phrase);

Speech is defined in GinSing through a series of speech fragments, commonly referred to as phonemes. There is not a direct correspondence from written word to spoken word, and GinSing does not provide this tranlation mechanism. There are however, several programs that can do this translation offline that you can use to create and tweak your phrases which generally work better than built-in on chip systems.
