You guys need to check out Vestec. Go buy a $25 SDK for your dev server. Tell them that the FS guys sent you and they'll refund your $25 (check via snail mail). I haven't had a chance to dig into this one yet but I fully intend to do so. However, if you guys are working on real solutions to real world problems then you're in a great position to give Vestec a test drive.

Hi,
I am going to look into Sphinx myself for IVR menus.
Recognition factor is not so much the software as it is the quality of the database and how well it is tuned. Tuning you can do yourself with tools provided from sphinx + it does exist a separate open source database that I believe you can use.
Doing IVR menus is feasible. But, to translate free speech you have a challenge called dialects. The fact is that recognition factor is not 100% even with people with the same dialect, and many dialects are very far out so analyze the language of your clients and make some very accurate questions to the vendor to ensure you get what you want.

I'm looking to provide a feature to transcribe voicemails into text for my users. I've looked at SpinVox (which was acquired by Nuance). Their licensing method doesn't seem particularly friendly or flexible. They charge per user and lock each license to a particular user's actual identity. If I have a user named John Smith, I have to buy a license from Nuance _for John Smith_. If John Smith stops using the voicemail to text feature, but I have another user named Jane Doe who wants to start using the voicemail to text feature, I have to buy a new license for Jane Doe. Since Nuance makes you pay for a license one year at a time, it gets expensive if you have any significant churn. Apart from that, it is just annoying to have to register users with another company. I'd like to buy 100 or 1000 or 10000 licenses and use them how I see fit and not have to bother with registering individual users with a provider of speech recognition services.
I am wondering if other FreeSWITCH users have recommendations for good voice to text services or software. I'd be happy to consider either a service or software. If software, ideally it would be free of course, but a reasonable cost would also be acceptable. I know about PocketSphinx, but is it really sufficiently high quality as to be useful for transcribing voicemails? I don't need 100% accuracy -- probably 80% or 90% would be good enough since I will also attach the WAV file and direct my users to use the WAV file when in doubt.
Any pointers or tips would be appreciated.
