Speech Marks

The following code sample shows how to use Java-based applications to synthesize speech marks for inputed text. This functionality uses the SynthesizeSpeech API.

For more information on this functionality, see Speech Marks .

For more information on the API, see the reference for SynthesizeSpeech API.
