How to add audio file in the prompt as part of Interaction

Interaction interaction = interaction("get-dtmf")
.addPrompt(new SpeechSynthesis("say a number between 5 and 10 digits long."))

Also how to use the grammar file while taking user input and collecting user input by listening to his voice

Instead of a SpeechSynthesis, use an AudioFileReference.

To specify a grammar, create a GrammarReference and put it into a SpeechRecognition object. Next, pass this object to the addPrompt and build methods of the Interaction.Builder.

Note: if you don't want the user to be able to barge-in, don't pass it to the addPrompt method.

See cookbook example.
