To complete this thread from February 2010:

Mr Chaumont Devin built in the past a TTS based on pre-recorded words
and still uses it.

Features of the English TTS:
- 78000 pre-recorded words,
- 5GB of disk space, wav files, 44100Hz,
- Each word is a separate wav file having the same name as the word in
  the text.

He also developed similar vocabularies for Hawaiian, the language of
Buru Island, Ambon Malay, formal Indonesian, and Vietnamese.

Please found below a sample:
