Subject: RE: roadmap to blind Rockboxing (need an audio amateur/speaker)
From: Lee Marlow (lmarlow_at_yahoo.com)
Date: 2004-02-26


Maybe we could have mp3s of all phonetic "syllables" for a language and then
read words on the fly using an algorithm like soundex or metaphone. These
algorithms decompose text into its phonetic pronunciation.

Information and source code for Soundex and Metaphone can be found here:
http://www.creativyst.com/Doc/Articles/SoundEx1/SoundEx1.htm
http://aspell.sourceforge.net/metaphone/

This way new words, directories, songs, etc. could be supported without
additional offline text-to-speech processing. This could be the fallback
method if a dirname.mp3 file doesn't exist for the directory or a new menu
option appears that hasn't been recorded yet. It probably wouldn't sound
very good, but it might make be sufficient.

Because this is pie-in-the-sky, versus for mp3 clips we have all the
infrastructure. mp3 clips from the buffer will take only minimum extra
resources, some slight changes to menu and screen code. A TTS engine is a
whole lot different.

For this we can use talkbox, and you can generate the directory name clips
offline on a PC, using a text-to-speach script, if you like.

Hu? No, you can have clips down to 1 frame, which is in the milliseconds.
And latency is also no issue, either we have the clips in the mp3 buffer
(while not playing), or we don't.
