Triphone Coverage Prompts

If you have contributed speech for all the Phoneme Coverage Prompts, you may be interested in contributing additional speech recordings using your own prompts.  User submitted prompts and recordings will help to ensure that we get submissions for as many different words as possible (especially words not already included in our Phoneme Coverage Prompts), and thus provide coverage for as many triphones as possible.  It is not enough to get many different people reading the same VoxForge created Phoneme Coverage Prompts files (why? because the resulting Acoustic Models will only be as good as the triphones covered in those files). We need a large variety texts to ensure we cover as many of the triphones in the English language as possible.  Be creative!

Suggestions for user-submitted prompts:

• Gutenberg Project - The Gutenberg project is a library of 17,000 free ebooks whose copyright has expired.  Pick one and record all or part of it.  Then submit a compressed audio version to the Gutenberg Audio Books project (e.g. mp3) and submit the uncompressed version (in wav format) to VoxForge.
• Wikipedia - Wikipedia is the free encyclopedia built collaboratively using Wiki software.  Pick your favourite article and record all or part of it. Then submit a compressed version of your audio (in ogg format) to the Spoken Wikipedia project and submit an uncompressed version (in wav format) to VoxForge.
• Google Books - Google Books gives you access to many out-of-copyright books that you can download (you need to select the "Full view" radio button when you search on books.google.com)

Don't worry if you don't have the time (or the inclination) to create VoxForge style prompts and/or audio files.  We can convert your "one big prompt file" and corresponding "one big speech audio file" (in uncompressed wav format) into VoxForge style prompt and audio files.  What is important is that we get as many varied speech audio contributions as possible.
