A new version of Microsoft Translator API has been announced by Microsoft yesterday, which has real time support for speech-to-speech (and speech to text) translation capabilities.
This new version of Microsoft Translator is the first end-to-end speech translation solution optimized for real-life conversations (vs. simple human to machine commands) available on the market. Before today, speech translation solutions needed to be cobbled together from a number of different APIs (speech recognition, translation, and speech synthesis), were not optimized for conversational speech or designed to work with each other. Now, end users and businesses alike can remove language barriers with the integration of speech translation in their familiar apps and services.
This is the same API which Microsoft Skype team use in Skype translator service and now businesses can use this translation feature to their applications and services.
