Mean Opinion Score (MOS) is a numerical measure that represents the perceived quality of audio samples, commonly used in evaluating text-to-speech systems. The score ranges from 1 to 5, with 1 indicating poor quality and 5 signifying excellent quality. These scores are derivedfrom comprehensive, professionally-conducted evaluations, and are anonymized to ensure unbiased results.

Signal Noise Ratio

Signal Noise Ratio

Signal Noise Ratio

The signal-to-noise ratio (SNR) is a crucial metric that measures  the amount of useful information vs. false or irrelevant background noise, frequently measured in decibels (dB). Engineers aim to maximize SNR to enhance system performance by minimizing noise interference.
