I am sorry for the ignorance on the matter, but how does google voice does? Do they also have humans? jmesquita On Tue, Aug 11, 2009 at 11:17 AM, Kirk Bateman <kirk.bateman@gmail.com>wrote:
I'm still interested in getting pocketsphinx to attempt speech recognition on an audio file.
To be honest, most of the problem is that at 8Khz (mobile phone call rate), speech detection is NOT very accurate, at 16Khz it IS significantly better.
I'm planning to have a play with the speechtools module and mod_pocketsphinx etc to try and get an audio file parsed, spare time permitting.
Will let the list know if I get anywhere.

Hi Pete,
I'm afraid that the answer's still the same: use a human. Here's an article describing the state of the art: http://www.theregister.co.uk/2009/08/05/spinvox_demo_day/ - the links to previous stories at the bottom provide good background.

I apologize, I should have been more clear. We will be using humans to scan the translated results. But we are looking for a system to perform the "first pass" on the audio to hopefully help the human type less.
Although the question has been raised if it's faster to have a human just transcribe the whole thing, or fix up what the computer spit out. If you have any insights on this, that would be great.

Good evening Pete,
The only way to do this is, I'm afraid, to use a human. We use Amazon's Mechanical Turk to good effect.
