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.
