The new Samsung Galaxy S20 series will be the first non-Pixel phone to get Google's Live Caption. The feature transcribes and captions videos in real-time with high accuracy. Google introduced Live Caption with the launch of Android 10 on the Pixel 4.
What doesn't seem to be coming to the Galaxy S20 yet is the Pixel's Recorder app. Using the same on-device transcription service as Live Caption, the Recorder app automatically transcribes recordings. For now, the feature looks like a Pixel-exclusive.
