The PlayAudioFromDisk sample illustrates how to play audio from files on disk. The sample plays wave (.wav) sound files containing music and a recorded prompt. The sample also plays prompts from a prompt database.

  • Playing audio from .wav files
  • Using a URI to reference .wav files
  • Using a StatementActivity
  • Using a prompt database
  • Using different sources of audio in the same StatementActivity object

Running the Sample

To run the sample

  1. In the Samples\Workflow\PlayAudioFromDisk\ directory of the Speech Server installation directory, open the sample solution file.

  2. To start debugging, press F5.

  3. In the Voice Response Debugging Window dialog box, click the SIP Phone tab, enter any numbers in the Called Party and Calling Party boxes, and then click Call.

    The sample plays a musical introduction from a .wav file, followed by a greeting played from a prompt database. The rest of the sample alternates between .wav files and prompts from a prompt database.

Remarks

The sample uses a version of the StatementActivity class AppendAudio method, which allows for entry of alternate audio material.

If the file referenced by the URI is not available, the application plays the alternate text using the text-to-speech (TTS) engine.
