Amazon Transcribe with multiple channels

0

I have a need to use Amazon Transcribe with files that contain multiple channels. But if the file contains more than two channels I get back an error message that says "You are using too many channels". Is 2 really the limit or is there some way to get it to recognize more channels? We don't care if we have to pay for each channel but we'd really prefer not to have to submit multiple jobs and merge the outputs ourselves.

Currently Transcribe supports 1 or 2 channel audios, which can be processed together or separately. Please see these link. https://docs.aws.amazon.com/transcribe/latest/dg/how-input.html#how-input-channels https://docs.aws.amazon.com/transcribe/latest/dg/channel-id.html

If you need to process more than 2 audio channel, there may be ways to create multiple Transcribe instances to handle that. Are you able to detail your application, source formats and current workflow?

  • Phone call related workflow? Recorded audio file? Video+audio processing?
  • audio files only? audio channels from a video?

Thanks for the response. Our application is involved with court reporting. We capture audio files from several different microphones during a session, and upload them for transcription later. So there's no video or real-time processing.

We discussed solving the problem with multiple Transcribe jobs. It will require a lot of work on our end since we already have a system built for 1 or 2-channel processing, but if that's the best way to do it we'll proceed. I wanted to check first to see if there was some easier way. I'd hate to do 100 hours of work if Amazon is planning to increase this limit soon.
