# Topics

The four subject headings used across the archive, with the notes filed under each of them.

## Dialogue

- July 28, 2026[What makes synthetic dialogue sound unrehearsed](https://diatts.com/notes/what-makes-synthetic-dialogue-sound-unrehearsed/)Two synthetic voices can be individually convincing and still fail the moment they have to talk to each other. The difference is almost never the timbre.

## Prosody

- June 12, 2026[Prosody is the harder half of speech](https://diatts.com/notes/prosody-is-the-harder-half-of-speech/)Getting the phonemes right is a solved-enough problem. Deciding which syllable carries the weight of a sentence is where synthesis still shows its seams.

## Data & Practice

- May 4, 2026[How to read a speech model card](https://diatts.com/notes/how-to-read-a-speech-model-card/)Model documentation is written to be skimmed and is most useful when it is not. A short guide to the sections that actually constrain what you can do.
- January 27, 2026[Preparing audio datasets for speech models](https://diatts.com/notes/preparing-audio-datasets-for-speech-models/)Most of the quality difference between two speech systems was decided during data preparation, long before either was trained.

## Evaluation & Ethics

- March 19, 2026[Consent and provenance in voice cloning](https://diatts.com/notes/consent-and-provenance-in-voice-cloning/)A few seconds of reference audio is now enough to reproduce a speaking voice. The interesting questions are all about record-keeping.
- November 15, 2025[Evaluating speech systems without a leaderboard](https://diatts.com/notes/evaluating-speech-systems-without-a-leaderboard/)Speech quality is a perceptual property, and perceptual properties resist the single number that comparison tables want.
