Well, being that we've looked at this problem at Voice Genesis for 3-4 years
now, I can tell you one thing:

User-independent Speech Recognition technology that exceeds 70% accuracy
with large vocabulary just doesn't exist.  IBM has put more money into this
than any other company... and, well, so far, there is nothing that can do
this...

Now, even after you train the engine (Sphinx is the top of the line
open-source engine...CMU stuff... as good in quality as any commercial
package)... there is still (as of mid 2005) speech recognition with large
vocabulary ( > 1000 words with all possible phrase combinations) absolutely
nothing out there that provides a technology that users will accept...

We're working on getting something similar to what is being discussed
here..., but not exactly... since there are limitations in the base
theory/technology.

Please include comments in reply-to fork-noarchive only.

If it's lower than about 80% it'd be useless, I'd bet. Only one way to
find out - I'll set up a little test. Any good open source speech reco
engines out there? If not - to the torrents!
