Microsoft Translator now supports Japanese speech translation


Today, Microsoft has announced that they have added support for Japanese language in their Translator service which is the first end-to-end speech translation solution optimized for real-life conversations. Previously available for Arabic, Chinese, English, French, German, Italian, Portuguese, Russian and Spanish language, Japanese joins them as the 10th language.

These technologies are then connected to perform the speech translation function:



  1. The sound is transcribed into text through the speech recognition AI
  2. TrueText then processes this text to remove unnecessary speech elements, such as redundant words or fillers like “um” (English) or “eto” (Japanese), that would generate poor translations
  3. The machine translation AI then translates each word using the context of the full sentence
  4. Finally, the text to speech generates the audio output from this translated text


With this release, businesses, developers, and end users alike will be able to use Japanese in the various apps and services offered or powered by Microsoft Translator:

You can translate any of the supported 10 Translator speech languages into any of the supported 60+ Translator text languages.
