Overview

Evaluates speech clarity and background noise levels in the audio.

​
Configuration

This detector does not accept configuration keys.

  "config": {}
}

​
Interpreting Results

  • snr.pass/music.pass: Individual checks that determine the overall pass/fail result.
  • snr_db/overlap_pct: Primary quality signals for speech clarity and music overlap.
  • speech_segments_count/total_speech_duration_sec: How much speech was detected.
