-The Speech Translation API supports different languages for speech-to-speech and speech-to-text translation. The source language must always be from the speech-to-text language table. The available target languages depend on whether the translation target is speech or text. You may translate incoming speech into any of the [supported languages](https://www.microsoft.com/translator/business/languages/). A subset of languages is available for [speech synthesis](language-support.md#text-languages).
