To check the accuracy of the AI-driven real-time transcription feature found in the Recorder app, the Wall Street Journal tested it against a courtroom stenographer named Anita Trombetta, who can type 260 words per minute on her stenographer machine. Recorder was also pitted against Fran Capo, who is one of the fastest talkers in the world, and four random people with different accents. Those going up against the Recorder app read the famous “To be or not to be” soliloquy from Hamlet, an article from the Wall Street Journal and a part of Google’s privacy policy.

The results? Recorder held its own against the courtroom stenographer. However, it didn’t do too well when Ms. Capo, who is listed in The Guinness Book of World Records as the fastest talking female (11 words per second) recited a rendition of The Three Little Pigs as a warmup. When Capo read from the prepared material, Google’s transcription technology was better with a few missed words (but the stenographer also missed a few words, noted the video). Lastly, the real-time transcription feature on the Recorder app went up against four random people from New Zealand, Ireland, Jamaica and Germany.

The Journal’s Joanna Stern, who conducted the test, said that the transcription feature was “damn impressive.” For those with an iOS or Android device other than the Pixel 4, Stern points out that Otter, available in the App Store and Google Play Store, does the same thing although not as well as Google’s app.

Imagine how useful this could be for taking notes at school or at work. The Pixel 4 and Pixel 4 XL go on sale tomorrow starting at $799.
