Question

3) If a client requests timestamping every two minutes, how would it look

Answer 1

In transcription timestamps are markers which indicate when the adjacent text was spoken. They are in the format [HH:MM:SS]. HH are hours, MM are minutes, and SS are seconds from the beginning of the video or audio file.
There are different kinds of timestamps like periodic timestamps, paragraph timestamps, sentence timestamps and speaker timestamps.
Periodic timestamps appear at a consistent frequency. They can appear for every 15 seconds, 30 seconds, 1 minute, or 2 minutes.
