+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.
+
+Support for non-English languages may be absent or thin due to weak G2P and/or lack of training data. Some languages are only represented by a small handful or even just one voice (French).
+
+Most voices perform best on a "goldilocks range" of 100-200 tokens out of ~500 possible. Voices may perform worse at the extremes:
+- **Weakness** on short utterances, especially less than 10-20 tokens. Root cause could be lack of short-utterance training data and/or model architecture. One possible inference mitigation is to bundle shorter utterances together.
+- **Rushing** on long utterances, especially over 400 tokens. You can chunk down to shorter utterances or adjust the `speed` parameter to mitigate this.
+
+**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
