Automatic Speech Recognition

ASR, or Automatic Speech Recognition is the ability to collect information from a caller without the use of DTMF (the caller’s keypad). Unlike some of our competitors who use speech engines with lower quality or smaller grammer sets, Nimblevox allows for a full set of grammar.

Nimblevox has the best speech recognition in cloud communications because we have partnered with Lumenvox. Nimblevox supports the complete suite of products from LumenVox including: ASR, Text-to-Speech, and Call Progress Analysis. LumenVox has won numerous awards for innovation and technical excellence. Based on industry standards, LumenVox’s core Speech Software is certified as one of the most accurate, natural sounding, and reliable solutions in the industry.

The “Collect” tab in the prompt node will be setup to accept custom grammar files.

The custom voice file tells the speech engine which words to accept.

      lincoln   austin   phoenix   houston    

The custom dtmf file will translate the keypad input values to the tag. So

1 lincoln will interpret the key press 1 to the city lincoln.

      1  lincoln    2  austin    3  phoenix    4  houston    

Once we receive the input we play the city back using the prompt text-to-speech. It is important to use interpretation and not the typical utterance when using custom grammars.
