I haven’t tried Nuance MRCP interface but I have lot’s of experience evaluating the Nuance technology.

Today, Nuance considered being the state-of-the-art in this field and they’re OEM’ing it to most tier-1 vendors, most notably: Microsoft and Genesis/Alcatel/Lucent. Most likely any ASR application you’ll encounter from a top-tier carrier today is based on Nuance.

I’m particularly familiar with Nuance NLP product and their extensive VXML interface and found it to be most efficient.

 

I’ve tested better hardware-based DSP speech verification/authentication engines but it was quite cumbersome to integrate with as opposed to Nuance ease of use.

 

The CMU sphinx and it’s realtime mini-version pocketsphinx are a great initiative and hopefully, as a university backed open source project, it will exceed Nuance strength and usability soon enough.

 

My 2c worth.

Can you instruct me / point me to instructions on how to use xlite or alike to talk into Nuance ASR via MRCP and see the spoken words on the console?

I don’t care about efficiency for the moment, I just want to evaluate Nuance.

BTW

What do you think of their ASR? Other ASRs?

 

 

mod_openmrcp was tested with Nuance along the way.  But you'll need to understand the speech interfaces in FreeSWITCH to use it effectively.
