Apple patents on-device audio transcription for video calls

Apple has been granted a patent for a system that converts spoken words into text during video or audio calls. The device receiving the audio creates the text locally using a pre-stored voice model and then sends that text to other participants. The system can also sync the text with video content so the words appear at the correct moment.

Why it mattersThis approach keeps voice processing on the user's device rather than sending audio to a server, which may improve privacy and reduce lag for people using video conferencing tools.

In the filing’s own words

Aspects of the subject technology provide for transcription of audio content during a conferencing session, such as an audio conferencing session or a video conferencing session. The transcription can be generated by the device at which the audio input is received, and transmitted to a remote device at which the transcription is displayed. Video content can also be provided from the device that generates the transcription to the remote device that displays in the transcription. The transcription can be provided with time information corresponding to time information in the video content, for synchronized display of the transcription and the corresponding video content.

What exactly they claim (claim 1)

1. A method, comprising: during a conferencing session between at least a first device and a second device: receiving, by the first device, a first audio input; generating, by the first device using a voice model previously stored at the first device and having been trained on one or more voice inputs from a user of the first device, a first transcription of the first audio input; and sending the first transcription from the first device to the second device.
