• I saw Lumenvox offering Speech Recognition for asterisk at a past Astricon.

• Thanks for the link. Are there no free alternatives for speech recognition?

• Daniel,

  try this http://zaf.github.io/asterisk-speech-recog/.

  I have tested it myself, it works very well.

• Thanks, this looks promising. I was wondering if there’s an easier way to get this to work inside FreePBX?
  I have all of the dependencies installed for it, but now I want to know if there’s a mod I can use in FreePBX to get it setup?

• I think I saw an old page on the voip-info wiki on how to use CMU Sphinx with asterisk.

  http://www.voip-info.org/wiki/view/Sphinx

  IMHO It’s not going to be anywhere as good as a commercial product without a lot of work.

• I use FreePBX as well. There is no module for speech recognition. You have too create a custom destination.

• Ok. Where I am now is, I copied the speech-recog.agi to the agi-bin directory. Where do I go from here?

• Read README, check the requirements and get the google speech api key.

  Then add a custom destination in FreePBX and edit your extensions_custom.conf.

• CMU Sphinx is really good if you know what sentences you want to recognise

  I am not sure how well it works with random stuff but if you have a list of common phrasings then you can do really well (having used it recently) – although I would say its much better at recognising North American speech than NZ. I think there are different language options too.

• Hi Daniel

  I wanted to try it, but I obtain the following error message:

  “speech-recog.agi,en-US: API key is missing. Aborting. “

  🙁

  What am I missing? Any hint?

• Yes… OK… but… where and how can I obtain this API Key?
  Where and how do I install it into my Asterisk box?

• Google?…

  Steve

• Yeah… searched “google voice recognition api asterisk”, browsed though various results. Nothing helpful for a beginner, very confusing bla bla…

  Thanks anyway for your help.

• if i remember correctly nerdvittles has a article
  “google speech recognition api asterisk” brings results

• Hello Frank,

  google indeed makes it very hard to figure out how to enable the speech API and get a key. I guess it is intentional since they still consider is a technology preview. Anyway have a look here on how to get there:

  Hope that helps,

  I see only today and not tested now.

  For enable API Key you need do it by Google Console and enabled the service for voice (not remember the name exactly)

• I really appreciated your hint. Many thanks!

  At the end, after checking several web sites, I gave up since everything seems a little too complicated for something I just wanted to try as a test.

  Thanks again!
