I’ve seen Microsoft employees claim that, properly trained, Windows’ speech recognition was 99% accurate.
#CORTANA TEXT TO SPEECH HOW TO#
Over time, a voice dictation program learns your accent, whether you pronounce the “a” in apricot like “bad” or “ape,” and how to filter out our unconscious verbal tics.
#CORTANA TEXT TO SPEECH SOFTWARE#
That, of course, was just the baseline. As anyone who’s used dictation software can tell you, the key to accuracy is training. The speech community seems split on whether relatively minor mistakes like this are significant. Windows also had an odd habit of interjecting the word “comma” when I was dictating the punctuation mark. In my tests, based on a methodology I developed for another speech recognition product I’m testing, Windows produced an accuracy rate of 93.6%, That’s pretty bad on paper, and somewhat behind the dedicated software I’m trying. If you used voice dictation software to write it, a 95.0% accuracy rate would mean you’d have to correct more than fifty mistakes. This story has 1,028 words in it, including subheadings. When I tested Windows’ speech capabilities, however, I experienced firsthand the merciless perfection that’s required for the system to be usable. That all begs the question: if Microsoft can deliver a solution like this for enterprise customers, why can’t it at least tap into the power of Cortana to deliver the same features for consumers? Video Indexer even auto-translates audio embedded in the video. Video Indexer also quickly allows a video to be searchable, allowing consumers to skip right to where they’re most interested. But if a user identifies an “unknown” speaker with their name, the entire database will be updated with the correct information, he said. Video Indexer, though, goes far beyond.Īccording to the product manager for Video Indexer, Milan Gada, the indexer can’t immediately identify every speaker in a video. For example, the company showed off a PowerPoint Translator function that will allow users to auto-configure a PowerPoint presentation in their native language. Video Indexer is an example of how Microsoft is applying artificial intelligence to daily tasks. Microsoft’s Video Indexer pulls an incredible amount of information from video uploaded to it. And it’s all searchable via a Web portal: If you only want to view the text from a specific speaker, you can. It even performs basic sentiment analysis, determining whether the words used are positive or negative. At its Build 2017 developer conference, Microsoft launched a new Video Indexer preview that not only transcribes the video, but also identifies the speaker, provides optional translations in up to nine languages, automatically generates subtitles, and guesses what objects or overlays are on the screen.
