I've just finshed a project on the ATtiny24v using the PWM as a DAC. Wonderful ! - A very easy device to use. Anyway, the tiny doesn't have enough memory to store a useful amount of audio, but it occured to me that it has enough omph to produce a variable frequency, harmonics and white noise. Spoken English is built up from phonetics, which are (roughly) vowels (swept freq) and constants (band passed white noise). There's (again very roughly) 20 vowels and 24 constants, which is should be possible to generate. (There's other considerations like inconsistancy of pronouciation and things like tempo and stress, but one thing at time). It may, therefore, be possible to write a program to convert ASCII into understandable speech.
Has anyone else actually done anything like this ?
Thoughts, suggestions, ideas, even constructive critism all greatly appreciated
