Microsoft PowerPoint

Presentation Translator is a PowerPoint add-in that brings real-time subtitles to presentations using Microsoft PowerPoint. Subtitles can be shown in the presenter’s language (to support accessibility scenarios) or in any of the 60+ supported languages provided by Translator. Powered by the Microsoft Translator live feature the audience can use their own device, to follow what the presenter says, in their preferred language.

Microsoft Office products offer translation using the AI-powered Translator service. Learn more about Translator’s text and speech translation.

To improve speech recognition and translation, the add-in extracts the content of your presentation to create a custom speech recognition model. Using Microsoft Cognitive Services’ Custom Speech Service, the add-in will use the content of both your slides and your notes to learn any jargon, technical terms, names of people and places, or acronyms you may be using in your presentation so that they appear correctly for the audience.

This add-in also lets you translate your presentation slide deck to any of the 60+ supported languages, fully preserving the formatting of your slides.

Members of the audience can use the Microsoft Translator app on their own mobile device or laptop to ask questions or make comments, spoken or written, which will appear on the presentation screen for all audience members to see when the presenter enables a Q&A session.

The list of supported speech recognition (presenter) languages and translation (subtitle, slides translations and personal device real-time translations) languages is available here.
