public class TextToSpeech
extends com.ibm.cloud.sdk.core.service.BaseService
```
The IBM® Text to Speech service provides APIs that use IBM's speech-synthesis capabilities to synthesize text into natural-sounding speech in a variety of languages, dialects, and voices. The service supports at least one male or female voice, sometimes both, for each language. The audio is streamed back to the client with minimal delay. For speech synthesis, the service supports a synchronous HTTP Representational State Transfer (REST) interface. It also supports a WebSocket interface that provides both plain text and SSML input, including the SSML <mark> element and word timings. SSML is an XML-based markup language that provides text annotation for speech-synthesis applications. The service also offers a customization interface. You can use the interface to define sounds-like or phonetic translations for words. A sounds-like translation consists of one or more words that, when combined, sound like the word. A phonetic translation is based on the SSML phoneme format for representing a word. You can specify a phonetic translation in standard International Phonetic Alphabet (IPA) representation or in the proprietary IBM Symbolic Phonetic Representation (SPR).

  - synthesize
```
public com.ibm.cloud.sdk.core.http.ServiceCall<java.io.InputStream> synthesize(SynthesizeOptions synthesizeOptions)
```
    Synthesize audio. 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. 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. **See also:** [The HTTP interface](https://cloud.ibm.com/docs/services/text-to-speech?topic=text-to-speech-usingHTTP#usingHTTP). ### Audio formats (accept types) The service can return audio in the following formats (MIME types). * Where indicated, you can optionally specify the sampling rate (`rate`) of the audio. You must specify a sampling rate for the `audio/l16` and `audio/mulaw` formats. A specified sampling rate must lie in the range of 8 kHz to 192 kHz. Some formats restrict the sampling rate to certain values, as noted. * For the `audio/l16` format, you can optionally specify the endianness (`endianness`) of the audio: `endianness=big-endian` or `endianness=little-endian`. Use the `Accept` header or the `accept` parameter to specify the requested format of the response audio. If you omit an audio format altogether, the service returns the audio in Ogg format with the Opus codec (`audio/ogg;codecs=opus`). The service always returns single-channel audio. * `audio/basic` - The service returns audio with a sampling rate of 8000 Hz. * `audio/flac` - You can optionally specify the `rate` of the audio. The default sampling rate is 22,050 Hz. * `audio/l16` - You must specify the `rate` of the audio. You can optionally specify the `endianness` of the audio. The default endianness is `little-endian`. * `audio/mp3` - You can optionally specify the `rate` of the audio. The default sampling rate is 22,050 Hz. * `audio/mpeg` - You can optionally specify the `rate` of the audio. The default sampling rate is 22,050 Hz. * `audio/mulaw` - You must specify the `rate` of the audio. * `audio/ogg` - The service returns the audio in the `vorbis` codec. You can optionally specify the `rate` of the audio. The default sampling rate is 22,050 Hz. * `audio/ogg;codecs=opus` - You can optionally specify the `rate` of the audio. Only the following values are valid sampling rates: `48000`, `24000`, `16000`, `12000`, or `8000`. If you specify a value other than one of these, the service returns an error. The default sampling rate is 48,000 Hz. * `audio/ogg;codecs=vorbis` - You can optionally specify the `rate` of the audio. The default sampling rate is 22,050 Hz. * `audio/wav` - You can optionally specify the `rate` of the audio. The default sampling rate is 22,050 Hz. * `audio/webm` - The service returns the audio in the `opus` codec. The service returns audio with a sampling rate of 48,000 Hz. * `audio/webm;codecs=opus` - The service returns audio with a sampling rate of 48,000 Hz. * `audio/webm;codecs=vorbis` - You can optionally specify the `rate` of the audio. The default sampling rate is 22,050 Hz. For more information about specifying an audio format, including additional details about some of the formats, see [Audio formats](https://cloud.ibm.com/docs/services/text-to-speech?topic=text-to-speech-audioFormats#audioFormats). ### Warning messages If a request includes invalid query parameters, the service returns a `Warnings` response header that provides messages about the invalid parameters. The warning includes a descriptive message and a list of invalid argument strings. For example, a message such as `"Unknown arguments:"` or `"Unknown url query arguments:"` followed by a list of the form `"{invalid_arg_1}, {invalid_arg_2}."` The request succeeds despite the warnings.

Specify a language to list the voice models for that language only. To see the words in addition to the metadata for a specific voice model, use the **List a custom model** method. You must use credentials for the instance of the service that owns a model to list information about it. **Note:** This method is currently a beta release. **See also:** [Querying all custom models](https://cloud.ibm.com/docs/services/text-to-speech?topic=text-to-speech-customModels#cuModelsQueryAll).

```
public com.ibm.cloud.sdk.core.http.ServiceCall<java.lang.Void> updateVoiceModel(UpdateVoiceModelOptions updateVoiceModelOptions)
```
    Update a custom model. Updates information for the specified custom voice model. You can update metadata such as the name and description of the voice model. You can also update the words in the model and their translations. Adding a new translation for a word that already exists in a custom model overwrites the word's existing translation. A custom model can contain no more than 20,000 entries. You must use credentials for the instance of the service that owns a model to update it. You can define sounds-like or phonetic translations for words. A sounds-like translation consists of one or more words that, when combined, sound like the word. Phonetic translations are based on the SSML phoneme format for representing a word. You can specify them in standard International Phonetic Alphabet (IPA) representation <phoneme alphabet="ipa" ph="təmˈɑto"></phoneme> or in the proprietary IBM Symbolic Phonetic Representation (SPR) <phoneme alphabet="ibm" ph="1gAstroEntxrYFXs"></phoneme> **Note:** This method is currently a beta release. **See also:** * [Updating a custom model](https://cloud.ibm.com/docs/services/text-to-speech?topic=text-to-speech-customModels#cuModelsUpdate) * [Adding words to a Japanese custom model](https://cloud.ibm.com/docs/services/text-to-speech?topic=text-to-speech-customWords#cuJapaneseAdd) * [Understanding customization](https://cloud.ibm.com/docs/services/text-to-speech?topic=text-to-speech-customIntro#customIntro).
