## Key Features and Statistic 📊
- **All audio is cleaned from noise and music.**
- **Clean cuts are made at the beginning and end of sentences to eliminate any unnecessary silences or disruptions, while avoiding cutting in the middle of words.**
- Sourced from 186 YouTube channels, with **channel IDs included for transparency**.
- Number of samples: 887,772
- Total duration: 1,016.97 hours
- Sampling rate: 24 kHz
- Number of splits: 1 (train only)
- Size: 169 GBs
- Gender distribution of speakers: 61.3% ± 3.02% male (manually estimated from a sample of 1,000 with a 95% confidence interval)
- Estimated transcription error rate: 1.8% ± 0.82% (manually estimated from a sample of 1,000 with a 95% confidence interval)
    - This metric is for quick reference purposes only; users of this dataset should carefully inspect it to ensure it meets your requirements.
    - The error rate only accounts for sentences with mistranscriptions (more or fewer words than expected).
    - Other errors, such as missing punctuation or incorrect but phonetically similar words, are not counted.
