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
Notes on speech recognition:Speech recognition does not recogniseunderstand every speaker and every word. Consider usingalternative command words if necessary. Short words, like “yes” areVery short words such as "no" can be more difficult to recognise. Ask callersTell the caller to speak slowly and clearly if the system does not recognise themanything. When specifying the command words consider how the word is spoken, rather, you should pay more attention to how a word sounds than how it is writtenactually spelt. This applies particularlyin particular to foreign words. The system will try to recognise these as if they had been spoken in the native language. For example:Support in German would be better like this: Sapport Download like this: Daunlohd
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
