WholeWord Speech Recognition feature

Type of feature

The Avaya Recognizer feature (previously known as WholeWord speech recognition) is a licensed feature. You must have RTU licenses to use this feature.

About the Avaya Recognizer feature

Avaya Recognizer enables the Avaya IR system to recognize and respond to spoken responses from callers. This feature also recognizes touch tones. Avaya Recognizer provides a "whole word" method to recognize caller speech by comparing an entire spoken word with a statistical model of the same word spoken by thousands of different people.

Avaya Recognizer is well suited to tasks where the required input is digits (0 to 9 and "oh") or "yes" and "no" responses. Standard vocabularies for Avaya Recognizer are available in the following languages:

• Australian English
• Brazilian Portuguese
• Canadian French
• Castilian Spanish
• Dutch
• French
• German
• Italian
• Japanese
• Latin-American Spanish
• UK English
• US English

The Avaya Recognizer feature has the following characteristics:

• Users can create and use custom grammars.
• All standard vocabularies for supported languages can recognize:
  • Digits zero through nine
  • "Oh" for zero where appropriate
  • "Yes" and "no"
  • Fixed-length connected-digit strings for a string length of one to ten digits (one to 24 digits for US English)
• Word spotting (meaning the keyword does not have to be spoken in isolation) is supported.
• Phrase screening (the ability of the system to determine whether or not a candidate keyword is a close enough match to be declared a valid keyword) is supported.
• The Avaya Recognizer engine supports both talk-off and barge-in interruption of a prompt.
• An NLSR proxy recognition type must be reserved for the Avaya Recognizer feature.
• The Avaya Recognizer engine is capable of gracefully denying a request for recognition if the system resources are too low, even if there is an available channel.
• Dedicated NLSR server and port numbers are not required, and channel resources may be shared.

  In a Prompt and Collect node of an application running touchtone and Avaya Recognizer in parallel, the application can accept either input and the system will not require separate port numbers or channels to be dedicated to each type of recognition.

• The Avaya Recognizer engine can start up automatically after a start_vs command is executed.
• Multiple languages are supported on a single system simultaneously (performance permitting).

Software requirements

The Avaya Recognizer feature requires the following software:

• Avaya Recognizer Base package
• Individual Avaya Recognizer language packages

Setup considerations

Avaya personnel must provision the RTU licenses before this feature can be used on the Avaya IR system.

Installation of each Avaya Recognizer language package includes the installation of the standard grammars for that language.

Using this feature

This feature is used by voice applications on the Avaya IR system. Avaya recommends using Avaya IVR Designer to develop applications with Avaya Recognizer capabilities. For more information, see Avaya IVR Designer Help.

Note:
VoiceXML applications in Avaya IR cannot use Avaya Recognizer. The VoiceXML feature currently only supports proxy speech recognition.
