Speech Enabled Menu

This block is only available if Integrated Speech IVR is enabled.

This block is similar to the Menu block with the addition of Text to Speech (TTS) and Automated Speech Recognition (ASR) speech capability. It is also an extension of the Speech Play and Collect block.

Properties	Values	Description
Menu Prompt	String	The sound file to play for menu options. Enter a .wav file, plain text, or Speech Synthesis Markup Language (SSML) string. For a .wav file, do one of the following: Enter a complete URL address to the file you wish to play. If your system administrator created a shortcut to the .wav files, enter /[file_name.wav].
Invalid Prompt	String	The sound file to play for an invalid choice. See the Menu Prompt description.
No Entry Prompt	String	The sound file to play if the caller does not enter anything within Max Time (for speech response). See the Menu Prompt description.
Stop Prompt On	Start of Input, Recognition Complete, or Don't Stop	This property determines if caller barge-in is enabled or disabled: Start of Input — the prompt is stopped as soon as the user starts to speak or presses a key on the phone keypad. Recognition Complete — the prompt is stopped only after recognition is achieved according to the configured grammar. This is also known as Hot Word mode. Don't Stop — no barge in during prompt.
Confidence Level (optional)	Percent	This is a confidence threshold parameter. The speech recognizer computes a confidence level. If the level is below the threshold you set, the recognizer returns no-match as the recognition result. If the level is at or above the threshold, then recognition is successful. The default is 50.
Speech Rate	Slow, Medium, or Fast	The rate a TTS message is read.
Volume	Soft, Medium, or Loud	The volume level a TTS message is read.
Termination Digits	0-9 # and *	Enter digit(s), # or * . These value(s) can be used by the caller to terminate this command. When a termination digit is pressed, playback stops, and the script executes the next block.
Clear Digits	Yes or No	Clear the digit buffer of any digits entered before playing the audio file. The default is No.
Max Time	Seconds	Maximum waiting time. The length of time the script waits for caller response after the prompt completes. The default is 20 and the maximum permitted value is 30. This property applies only to Automatic Speech Recognition (ASR).
Max Silence	Seconds	The maximum length of time to wait for the caller's next response. The default is 5.
Max Tries	Integer	Maximum number of times the caller can respond to a prompt. The default is 1.
Result Variable	String	Name of a variable into which the digit string is to be passed. Must start with an alphabetic character and not exceed 255 characters in length. There is no default value for this, so leaving this field blank causes this block not to function properly. See How to use variables.
Input Mode	Speech and DTMF, Speech only, or DTMF only	If you select Speech and DTMF, and if the caller presses a key (DTMF), the system ignores anything the caller says after the key press. If you select Speech and DTMF, and if the caller speaks, the system ignores any key press after anything the caller says. The default is Speech and DTMF.
Close MRCP Session	Yes or No	Close the MRCP session after leaving the MRCP block.
Comment	Text	Optional description of this block in your script.

Configure the Speech Enabled Menu block

Right-click the block and click Add case. The Speech Enabled Menu dialog appears.

Perform one or both of these steps:

From the Speech Enabled Menu list, select one or more menu items.
In Or said, type the text for matching the caller's spoken response. You can type up to 15 separate words. Separate the words with semicolons (";").

Note

This is an alternative spoken response option for the caller.
The case accepts any one of your selected digits or words if the caller response is matched in this case.

Optionally, in Label, type an alternative description.
Click OK. The Case branch appears.
Connect the Case branch to the appropriate block in the script.
Repeat steps 1-5 to add the branches you need.
Connect the Else branch to the appropriate block in the script.
