# Kokoro Science and Microbiology STT Synthetic Dataset

Synthetic English scientific speech generated with `hexgrad/Kokoro-82M`.

## Current contents

- **8,995 utterances**
- **20.000 measured hours**
- 16 kHz mono embedded FLAC audio
- `text`: desired ASR transcript
- `tts_text`: pronunciation-friendly text supplied to Kokoro

## Corpus generations

- `v1_10h_original`: original approximately 10-hour release
- `v2_20h_expansion`: second tranche bringing the dataset to 20 measured hours

## v2 expansion focus

- mM vs mL and µM vs µL unit/context contrasts
- dilution notation and CFU enumeration
- microbiology organisms and selective media
- antimicrobial susceptibility and MIC language
- molecular biology and qPCR terminology
- laboratory QC and reporting language

Synthetic speech is useful for domain adaptation, but real-human scientific speech should remain an independent validation target.
