Voice recognition menus only piss people off. If you're setting up a call center where you want as many as possible of the customers to ABANDON their calls, go on... roy
Spinvox have a distinct advantage over most telephony applications in that their speech recognition does not have to occur in realtime - it simply records the speech and then processes it afterwards. I strongly suspect since the company always acts very tight-lipped about their technology that it relies heavily on human operators. Think about it if the average translation of voicemail to text message was to take 2 mins, that would cost them about 20p per message if they use minimum wage UK workers. Make that under 3p per message in the more likely scenario that they are using a call-centre in India. Since they charge you 25p per message this is a feasible business model, and one that hasn't got to rely on any bleeding edge technologies. -- Adam Holt Bayham Systems Ltd Web: http://www.bayhamsystems.com/ Email: adam.holt@bayhamsystems.co.uk Address: No. 1 Farnham Road, Guildford, Surrey, GU2 4RG, United Kingdom>Hi > >I dont know jack about speech recognition, however since this topic came >up anyonw know how spinvox do speech ercognition, in fact its so good it >converst the speech to text and sends the voicemail as a SMS, I think a >awesome addone to the sms module in asterisk. > >Iqbal
Agreed, Steve. Iq, Maybe it is for your voice, but speech to text is a long ways away from being as advanced as you think it is.

Disagree with you Matt. Check out www.angel.com If anyone wants some contacts over there email me. I'm sure they would be happy to set up on API for utilizing their services in conjunction with asterisk.

Trevor, I used to sell Nuance when I worked for Fujitsu. When I first came across Angel.com about 12 months ago I knew this was the right way to approach NLVR. The Nuance costs are unrealistically astronomical mainly due to the 'high touch' consulting fees that are imposed on this kind of rollout. Angel.com being web based and delivered is able to deliver 90% of the solution for 20% of the costs can only be a good thing.

Steve then you have had your head up your arse for a number of years. Nuance was delivering 90% in 1999 and I have a number of happy customers to prove it. You also obviously didn't look at either the Nuance or angel sites because both of them offer free form speech to text capabilities. One of the first customers I had in Australia for Nuance was ordering of stock for Revlon cosmetics using a speech to an automated ordering system using their antiquated stock database.

We were talking about free form speech to text. That is a world apart from a voice activated IVR. Besides that, I have never found a voice activated IVR in English that gets better than about 30% accuracy on a fairly limited decision. A slight divergence from the typical 98% they claim. In contrast, I have seen very good accuracy for Cantonese and Mandarin, which have been less intensively developed.

The limited domain reference is obsolete, Telstra have a 2 million record database (yeh I know it's a lot smaller when you dice it phonetically but it's still big enough). -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Steve Underwood Sent: Sunday, February 13, 2005 9:57 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Speech Recognition Hi Dean, You seem to have had your head up the supplier's arse for a number of years. :-) I last tried a Nuance demo system in about 2002, and found it useless. Speechworks (now scansoft) was rather better, but still useless for English. I'm British. Trying the British system gave poor results. Trying the US system seldom gave the right answer. Speechwork's Chinese (Cantonese and Mandarin) was pretty good, though. I've never seen Nuance offer free form speech to text, and I can't see Angel or Nuance's sites claiming that. They offer free form IVR input within a limited domain, which is something quite different - the set of possible outcomes is so much smaller. The best free form speech to text systems still require considerable user specific training to achieve reasonable accuracy. Some people eventually get good results, while others never do. Maybe some people just talk in a much more consistent way.

Ed can I ask you a question, Not trying to influence you one way or the other but why deal with the 'issues' of speech recognition when what you are looking to achieve is easily met with dtmf codes. Dtmf, works, is easy to manage and well established. Speech should only be used when you need to enter complex controls with more than '9' easy options etc. Just a thought.
