# Voices

For each voice, the given grades are intended to be estimates of the **quality and quantity** of its associated training data, both of which impact overall inference quality.

Subjectively, voices will sound better or worse to different people.

**Target Quality**
- How high quality is the reference voice? This grade may be impacted by audio quality, artifacts, compression, & sample rate.
- How well do the text labels match the audio? Text/audio misalignment (e.g. from hallucinations) will lower this grade.

**Training Duration**
- How much audio was seen during training? Smaller durations result in a lower overall grade.
- 10 hours <= HH hours < 100 hours
- 1 hour <= H hours < 10 hours
- 10 minutes <= MM minutes < 100 minutes
- 1 minute <= M minutes < 10 minutes
