Talkie TALK

[arpeggio1234]

Hello, i am a great fan of the Arduino and the Speakjet robot voice,
Came accross the Talkie, and like it alot, thanks for that.
My question is: Is it possible the apply Pitch, Speed and a kind of filter sound parameters
to the Talkie library voices, Are there 0x4D and 0x3C binary numbers involved in this,
Thanks in advance, Dian from the Netherlands

And Ps does anyone of you know where they still sell Babblebot,
aka soundgin chips
