We offer a variety of other features as well.
[Timestamp Display and Synchronized Playback]
This serves as an alternative to the speaker separation function.
It displays timestamps, and you can click the play button for a block to start playback from that specific point.

When you select the "Action" tab, buttons are created below the transcription results. You can perform actions by clicking these buttons.
