Microsoft’s test area ‘Garage’ has released a PowerPoint tool which promises to translate into multiple languages your speech to accompany a presentation.

Presentation Translator translates your spoken remarks and posts them as subtitles on the slide deck.

It does more than show subtitles on the big screen.

Audience members can use their own device to see a translation in their preferred language.  The presenter can speak in one language (eg German) with audience members reading sub-titles in any one of 60 languages (eg French, Japanese, Chinese, English etc).

Slide text and notes can be included in the translation.

This is done via the Microsoft Cognitive Services API which is used in Cortana and the new Dictate ‘Speech to Text’ add-in for Word.   The engine translates moderately well but responds in ‘fits and starts’ with gaps between streams of translation.

Don’t expect fast real-time translation like Captains Kirk and Picard get!  This isn’t a Babel Fish (to switch sci-fi universes).

The voice and text from a presentation is sent to Microsoft’s servers for translation.  Something to keep in mind, especially for confidential briefings.

PowerPoint Translator has some notes about Privacy but it’s not a full, proper disclosure.  Note our highlighting.

” A note about privacy
Presentation Translator is powered by machine learning and the voice and text information you provide for translation will be used to improve Microsoft products and services. We protect your privacy by taking steps to de-identify your data and keep it secure.

Presentation Translator lets you broadcast subtitles to anyone with a 5 digit access code that is unique to your presentation. You may block this access to your information by using the “Lock conversation” setting.

By continuing to use Microsoft Translator, you agree to our Privacy Statement and Services Agreement. “

Data collected can be used in the development of the service but that’s not all.

More importantly, Microsoft doesn’t say ‘upfront’ other uses of the information you send to them.  In particular the ability of government agencies to get the content of presentations, with or without notice to the user or even without a warrant.
