Mean opinion score

Our MOS testing approach benchmarks and evaluates your speech (TTS) model's performance to make them work in the most efficient and effective way possible.

  • You obtain a comprehensive and fair assessment of the AI voice models you are evaluating.
  • As the approach is free of subjective bias and objective differences, user satisfaction measured with MOS technique is closer to reality.
  • Using our growing community of over 500,000 vetted crowd members to test and validate speech data reinforces data quality free from novice testing and arbitrary human thinking and assumptions.
  • We provide the aggregate of Mean Opinion Score in addition to the individual evaluations, making tester's or validator's job error-free.
