public class TextToSpeech
extends WatsonService

### Service Overview 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).

Instantiates a new `TextToSpeech`.

TextToSpeech

public TextToSpeech(java.lang.String username,
            java.lang.String password)

Instantiates a new `TextToSpeech` with username and password.

Parameters:

username - the username

password - the password

TextToSpeech

public TextToSpeech(IamOptions iamOptions)

Instantiates a new `TextToSpeech` with IAM. Note that if the access token is specified in the iamOptions, you accept responsibility for managing the access token yourself. You must set a new access token before this one expires or after receiving a 401 error from the service. Failing to do so will result in authentication errors after this token expires.

synthesize

public ServiceCall<java.io.InputStream> synthesize(SynthesizeOptions synthesizeOptions)

Use the `Accept` header or the `accept` query parameter to specify the requested format (MIME type) of the response audio. By default, the service uses `audio/ogg;codecs=opus`. 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. **See also:** [Synthesizing text to audio](https://console.bluemix.net/docs/services/text-to-speech/http.html#synthesize).
