Accepts input from the telephone keypad and through speech recognition.

<max digits> Maximum number of digits allowed to enter by the user.

[wait in seconds] Duration in seconds to wait for inputs. If this parameter is 2, the IVR will wait for a maximum of 2 seconds to get the input from the user. This countdown value will be reset after each input.

[enter key] The key to be pressed by the user on completing the input.

[esc key] Key pressed by the user for canceling the previous value entered.

[mask] This optional argument is used for filtering the input. The default mask is "0123456789".

Return Value

Returns the entered value/recognized word.

Remarks

• The input() will accept a maximum of <max digits> numbers entered through the telephone keypad or when recognized through speech with the Xtend IVR waiting for a duration of [wait in seconds] between two consecutive inputs or until the [enter key] is pressed. The function returns the entered value/recognized word.
• The pre-defined variable $InputMode recognizes the mode of Input() operation. The mode of input operation can be classified into pulse (P), tone (T) and speech recognition (S).

1) When mode of input() is through telephone keypad:

  MAIN:
    answer
    Play "Welcome.wav"
	
    $num = Input(2,3,#,*,"02468")
    Play "YouEntered.wav"
    Play Num2Wav($num)
	
    Hangup
    goto MAIN

 

2) When mode of input() is through speech recognition:

  MAIN:
    answer
    //Enable grammar and set the words to be recognized
    .....
    $retry = 3
    while $retry > 1
      $retry -= 1
      //Accept a number between 0 - 9
      play "song.wav"
        while true
            $Key = input(1,7)
            if $InputMode == "S"
                if srConfidence() >= 100
                    break
                endif
            else
                break
            endif
        endwhile
		
        if $InputMode == "S"
            //Perform a translation to the appropriate keypress
            .....
        endif
        .....
    endwhile
	
    play "thank.wav"
    hangup
    goto MAIN

• Here Input() waits till a word is recognized or a 7-second delay with no key press, which ever is earlier. If mode of input is through speech recognition then compare the recognized word with the defined words and play the corresponding wave file.
