How do I use text-to-speech in announcements?

You can configure an Announcer applet and Menu applets to announce some text in a voice of your choosing. You can either define the exact text to be announced , or the data sources that will contain the text to be announced at run time, in the applet. You can also specify the voice you want to use for the text in the applet, or use a data source that will contain the name of the voice at run timeruntime. For information about the Announcer appletand Menu applets, see Announcer applet and Menu applet.

...

1. In the same interaction plan as your data sources (if using data sources), create an Announcer or Menu applet.

2. In the Announcement type list, click Text

   . The Voice and Text fields appear

   to speech. Depending on which applet you are creating, you can configure the voice that announces the menu options in different ways.

To announce the menu options in a voice that is set at runtime from the data source you define in Voice data source, select Dynamic voice. Voice data source appears. Voice data source contains a list of available data sources. Select the data source that will contain the required value at run time.

   title Announcer applet
   If you are creating an Announcer applet, Voice appears. In Voice, define the voice you want to use to announce the text. You can use either a static value or a dynamic value from a data source. To use a static value, type the voice you want to use. The applet validates the voice when you click Update. To use a dynamic value from a data source, type the dollar sign ($). A list of available data sources appears. Click the data source that will contain the required value at run time. For example, $(Contact|TextToSpeech_voice__c). The Voice field can contain a maximum of 50 characters.

   Whether you use a static or dynamic value for the voice, it must match the voice ID provided by Amazon Polly. The voice is not case-sensitive. For a list of voices available in Amazon Polly and their IDs, see Voices in Amazon Polly (Amazon help).
