How It Works

1

Modern PBX systems record calls in 2 channels — agent on one, customer on the other.

2

Our model processes each channel separately, following every utterance in sequence.

3

It predicts the next response using previous dialogue context — dramatically reducing errors.

We can also help fine-tune transcription for your specific domain and terminology.

How multichannel transcription works — two audio channels become a perfect transcript

Speaker Diarization

Two options available:

  • stereo Left/right channel separation. Use when your PBX records agent and customer on separate channels.
  • ai Neural network-based detection. For single-channel recordings.

Response Example

    },
