## An earlier version of the dataset contains some duplicated data, a fix is on the way. Sorry for the inconvenience

## Cantonese Youtube Pseudo-Transcription Dataset
- Contains approximately 10k hours of audio sourced from YouTube
  - Videos are chosen at random, and scraped on a channel basis
  - Includes news, vlogs, entertainment, stories, health
- Columns
  - `transcript_whisper`: Transcribed using `Scrya/whisper-large-v2-cantonese` with `alvanlii/whisper-small-cantonese` for speculative decoding
  - `transcript_sensevoice`: Transcribed using `FunAudioLLM/SenseVoiceSmall`
    - used [OpenCC](https://github.com/BYVoid/OpenCC) to convert to traditional chinese
    - isolated event tags to `event_sensevoice`
    - isolated emotion tags to `emotion_sensevoice`
  - `snr`: Signal-to-noise ratio, extracted from `ylacombe/brouhaha-best`
  - `c50`: Speech clarity, extracted from `ylacombe/brouhaha-best`
  - `emotion`: Emotion, extracted from `emotion2vec/emotion2vec_plus_large`
- Processing
  - The full audio is split using [WhisperX](https://github.com/m-bain/whisperX), using `Scrya/whisper-large-v2-cantonese`
  - Preliminary filtering includes filtering out phrases like:
    - `liking/subscribing to YouTube channel`
    - `subtitles by [xxxx]`
    - Additional filtering is recommended for your own use
