Microsoft Claims Its Speech Transcription AI is Now Better Than Human Professionals (qz.com)

Microsoft announced today a system that can transcribe the content of a phone call with "the same or fewer errors" than real actual human professionals trained in transcription -- even when the human transcript is double-checked by a second human for accuracy. As you can imagine, this is a huge milestone for speech recognition. From a Quartz report:The team doesn't attribute this achievement to any breakthrough in algorithm or data, but the careful tuning of existing AI architectures. To test how their algorithm stacked up against humans, first researchers had to get a baseline. Microsoft hired a third-party service to tackle a piece of audio for which they had a confirmed 100 percent accurate transcription. The service worked in two stages: one person types up the audio, and then a second person listens to the audio and corrects any errors on the transcript. Based on the correct transcript for the standardized tests, the professionals had 5.9 percent and 11.3 percent error rates. After learning from 2,000 hours of human speech, Microsoft's system went after the same audio file -- and scored 5.9 percent and 11.1 percent error rates. That minute difference ends up being about a dozen fewer errors. Microsoft's next challenge is making this level of speech recognition work in noisier environments, like in a car or at a party. This implementation is crucial for Microsoft, and goes well beyond just transcription.

    Automated closed captioning for the hearing impaired would be one. I'm not hearing impaired, but I use the CC system with the volume low when I am watching TV while everyone else in the house is sleeping. I also use it when everyone is awake and noisy. It is amazing how awful some CC can be.
