ASR Menu

Routes the caller according to whether the caller's spoken input matches one or more configured items in a grammar file.

This could be used to prompt a caller for the name of the person or department they wish to speak to. You can specify an ASR confidence level to determine how close a match is required between the caller’s spoken input and grammar file entries.

Grammar files are set up by Content Guru based on your requirements. Contact your local support representative for advice.

Properties

Media List/Introduction/No Response/Invalid Response prompts

Use the Select Media List option to select the media list containing the audio files to use the three optional audio prompts supported in this action cell (Introduction, No Response, and Invalid Response).

Then, either use the Select... options lists to select the files or use the Use Dynamic... options to use local string variables containing the names of the files. You can choose to play the system default prompts instead of your own.

Alternatively, use the Use Dynamic Media List option to use a local string variable containing the name of the media list and then use a local string variable containing the name of the file in the media list (or select 'None' to use the system prompt).

Timeout Duration

Select the duration for which to wait for a response. On expiry, the service ends or the call is routed from the Interpretation Not Found exit point, if present.

Maximum Number of Attempts

Select the number of attempts to allow the caller to speak. After this, the service ends or the call is routed from the Interpretation exit point, if present.

Grammar file

Select the grammar file in the same manner as the introduction/no Response/invalid response prompts.

ASR Confidence Level Threshold

Enter a value between 0 and 100 to control how close a match is required between the caller’s spoken input and the defined words and phrases. A very low value increases the likelihood of false matches being found whilst a very high value decreases the likelihood of any match being found.

Interpretation

Enter the string variable in which to store the configured 'interpretation' value from the grammar file when a match is found.

Confidence Level

Enter the integer variable to store the system's calculation of the confidence level.

Exit points

Exit point

Taken

[Interpretation Found]

If the spoken input matched an item defined in the grammar file.

[Interpretation Not Found]

If the spoken input does not match an item defined in the grammar file.

Error

If a media list and/or prompt could not be located.
