Microsoft Translator Speech API

Microsoft Translator Speech API, part of the Microsoft Cognitive Services API collection, is a cloud-based machine translation service. The API enables businesses to add end-to-end, real-time, speech translations to their applications or services. Based on the industry standard REST technology, it can be used to build applications, tools, or any solution requiring multi-language speech translation regardless of the target OS or development languages.

Built for business, Microsoft Translator is a proven, customizable, and scalable solution for machine translation. Microsoft Translator technology powers speech translation features across Microsoft products, including Skype Translator, and the Microsoft Translator iOS and Android Apps.

Speech translation is available from several languages. Speech-to-text translation is available from any of these languages and to all of Translator’s 60 supported languages.

Where can you use speech translation?

Microsoft Translator can be used to cost-effectively expand the reach and improve the experience across a variety of use cases.

Let’s look into a bit more details on a few of these use cases:

  • Real Time Presentation Translation: Translate what a speaker says into 60 languages and enable users to follow a presentation or class by providing them with real-time subtitling, in the language of their choosing. Additionally, if saved, they can be used as presentation transcripts in multiple languages.
  • One-to-one in-Person or Remote Communications: A typical use case example of product solutions are the Microsoft Translator apps (for in person) and Skype Translator (for distance communication).
  • Customer Support: When your Call Center is experiencing an abnormally high-volume of calls, the integration of Microsoft Translator speech API into your infrastructure will add extra coverage for support. Or if there are special events that cause an influx of foreign language speakers into your customer service area, Microsoft Translator can extend your language offering (sporting/cultural events, tourist season, etc.)
  • Business Intelligence: Analyze your audio files by translating them into searchable text for your business decision makers to provide insights on sentiment analysis, customer service call logs analysis to identify trends on issues or identify early or new problems.
  • Media Subtitling: Provide automatic close captioning and subtitling in 60 languages for your live or recorded media events: webcast, broadcasts and when you’re offline use Azure Media Services.
  • Multi-Lingual AI Interactions: Enable natural multi-lingual interaction with your AI powered solutions by integrating Speech translation in the experience.
