Attached is a very
crude attempt at speech synthesis using Chip's recently posted VocalTract object. The "talk" object is quite rough around the edges, and to say that some of my phonemes are barely intelligible gives them way
too much credit. But maybe with input from the community and some fine tuning (okay, coarse tuning), the quality can be improved over time. Chip's marvelously compact object has everything that's needed for intelligible speech. But like any tool of its utility and complexity, it needs to be mastered; and that takes time.
I've relied heavily on this paper
for the formant values used in the program. The internet has many other valuable resources for synthesized speech, some dating back decades. This can be a problem, too, since much of the seminal work on the subject was done before the internet existed, and the resulting papers have likely never been converted to machine-readable form and posted.
Much of what is done here via individual argument lists might more efficiently be accomplished by table-driven methods. But in its current form, it's somewhat more readable, which is important for development and debugging. Plus it makes playing with the settings a little easier.
The attached archive includes the latest (v1.02) IDE/compiler exe. If you haven't already installed that version, copy the exe from the ZIP over the existing copy in your Propeller IDE directory.
Anyway, for what it's worth, enjoy!
Attached is a somewhat improved version. Some of the consonants are better, there are more demos, and I've added whispering and a spell
procedure. 'Still some extraneous popping and hissing to cure.
Added inflections, rolled r's, better musical notation, on-the-fly tempo adjustments, multiple speakers.
