You might check out http://Nexiwave.com They have been active at Cluecon and have a web API that does fully hosted ASR on WAV's or MP3's. They are doing innovation around running their ASR in GPU clusters, which means their internal cost of operation is likely to be the lowest in the industry. Good ASR is always going to be computationally intensive, so it is helpful to have somebody managing that for you. It's going to be a lot easier that trying to juggle your own sphinx training sets. http://nexiwave.com/index.php/pricing --pehr On Wed, Jun 22, 2011 at 9:54 AM, Hector Geraldino < Hector.Geraldino@ip-soft.net> wrote:

Hi everyone,****

I want to check with you guys to see if anyone has experience integrating FreeSwitch with an ASR engine, and using the engine as a merely transcriber of the conversation. ****

I’ve been playing for the past two weeks or so with Nuance Speech Server/recognizer and pocketsphinx. Nuance is by far a better solution, but due to the lack of freely available documentation and my short expertise in this subject, I haven’t been to achieve my goal.****

The communication between FS and the ASR engine works great using MCRP, my concern is with the ASR engine itself. I want to allow the user to speak freely, and get a transcription of what the user said. I don’t want or need to understand what the meaning of the utterances are (definitely the engine doesn’t need to do that), also I don’t need/want to write any complex grammar or SLM to get an interpretation of the spoken phrases, I just want the plain text of what has been said. No decisions will be taken based on what the user said, this information will just be passed to a 3rdapplication. ****

I don’t know if this can be achieved or not without developing grammars (not suitable for open-ended dialogs) or training statistical language models. What I do recall is using Dragon Speak in MS word for dictation, without the need of doing some trtraining or developing grammars. That’s exactly what I’m pursuing: a simple plain text transcription of the spoken words.****

Have anyone of you deal with something like this by any chance?****

Thanks for your help. I apologize if this is not the right place to ask this type of questions.****

Thanks again,****

Hi Hector, the point with Dragon Speak is that it already has a language model buil-in (and an acoustic model as well). It's not just an ASR engine. To solve your problem, you must have an ASR engine + statistical language model (LM) + acoustic model (AM). These three parts together can be called ASR system and it can be built directly from entreprises like Nuance and Loquendo. But if you want to use a free ASR system you'll have to combine a free engine + a free statistical LM + a free AM. Two known free engines are Sphinx and Julius. I think that you can find some free english LMs and english AMs supported by these engines at http://www.voxforge.org/ and http://www.keithv.com/software/. One problem that you'll face with these free engines is the lack of MRCP support. But it can be easily solved just by writing a simple module in FS (for example, see mod_pocketsphinx.c that comes with the source code of FS). I hope it helps ...
