Examples with SynthesizeOptions com.ibm.watson.text_to_speech.v1.model.SynthesizeOptions used on opensource projects

Example 16 with SynthesizeOptions

use of com.ibm.watson.text_to_speech.v1.model.SynthesizeOptions in project java-sdk by watson-developer-cloud.

the class TextToSpeech method synthesizeUsingWebSocket.

/**
 * Synthesize audio.
 *
 * <p>Synthesizes text to audio that is spoken in the specified voice. The service bases its
 * understanding of the language for the input text on the specified voice. Use a voice that
 * matches the language of the input text.
 *
 * <p>The method accepts a maximum of 5 KB of input text in the body of the request, and 8 KB for
 * the URL and headers. The 5 KB limit includes any SSML tags that you specify. The service
 * returns the synthesized audio stream as an array of bytes.
 *
 * <p>### Audio formats (accept types)
 *
 * <p>For more information about specifying an audio format, including additional details about
 * some of the formats, see [Audio
 * formats](https://cloud.ibm.com/docs/text-to-speech?topic=text-to-speech-audioFormats#audioFormats).
 *
 * @param synthesizeOptions the {@link SynthesizeOptions} containing the options for the call
 * @param callback the {@link SynthesizeCallback} callback
 * @return a {@link WebSocket} instance
