Translator Speech API Documentation

Microsoft Translator Speech API, part of the Microsoft Cognitive Services API collection, is a cloud-based machine translation service that provides speech to speech or speech to text translation. Based on the industry standard REST technology, it can be used to add end-to-end, real-time, speech translations to any application, tool, or solution requiring multi-language speech translation regardless of the target OS or development languages. For the list of supported languages, see the Supported languages article.

NOTE:The new Speech Service and SDK is replacing the Translator Speech API, which will no longer work starting October 15, 2019. For information on switching to the Speech Service, see Migrating from the Translator Speech API to the Speech Service
