Function

This module detects a DTMF input (tone dialling) or spoken words (ASR, Automatic Speech Recognition) and executes a branch in the program. To prompt the user to press a key, a voice prompt is played.

If no input is recognised, or an incorrect digit is pressed or a word is not recognised, an error voice prompt can be configured which is played to reprompt the user to try again.

Program execution continues using the output which corresponds to the DTMF key pressed or the word spoken. If this output is not connected, and the maximum number of allowed tries has not yet been reached, the error voice prompt is played and recognition is restarted. If the maximum number of tries is reached, program execution continues at the error output. If no object is connected to this output, the system hangs up.

Parameters

 Object Name

The name of this object instance

Prompt Type

Choose a prompt type

Voice Prompt

Choose a prompt

Error Voice Prompt Type

Choose the type of the error voice prompt

Error Voice Prompt

Choose the error voice prompt. This parameter is optional. If you
do not specify this parameter, then no error prompt is played.

Play Tone

If you use this option, the system will play a beep indicating when
the caller is expected to respond.


Maximum Tries

How often the object is re-executed when an error input is made
or no input is detected. If this counter is reached, program
execution continues at the error output.

Barge In

If activated, input is allowed whilst voice prompts are being played.
Otherwise it is allowed when playing has completed.



Command Word 0 ... 9

Here you define what spoken words are equivalent to the
corresponding DTMF keys. You can add several words to
one parameter, separated by commas. For example:
Command Word 1 - Reception, Central Office
Command Word 2 - Sales, Marketing, Purchasing

Notes on speech recognition

Speech recognition does not understand every speaker and every word. Consider alternative command words if necessary. Very short words such as "no" can be more difficult to recognise. Tell the caller to speak slowly and clearly if the system does not recognise anything. When specifying the command words, you should pay more attention to how a word sounds than how it is actually spelt. This applies in particular to foreign words. 

Example:

  • Specify Schadenfreude like this: Chahdenfroyder

Alternative words or interpretations by the speech recogniser

Some speech recognisers "interpret" the spoken words. 

For example, if you say the word "one", the Azure speech recogniser will return the result "1". So if you want a number to be spoken, be sure to enter this as an alternative. 

Examples

  • one,1
  • two,two,2
