## Cantonese Radio Pseudo-Transcription Dataset
- Contains 14k hours of audio sourced from Archive.org
- Columns
  - `order_index`: Represents the order of the audio compared to those from the same `filename`
  - `link`: Link of the original full audio
  - `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`
  - Note that `id` does not reflect the ordering of the audio within the same video
- Processing
  - The full audio is split using [WhisperX](https://github.com/m-bain/whisperX), using `Scrya/whisper-large-v2-cantonese`
    - it is split in <30s chunks and according to speakers
  - No filtering or additional audio processing was done for this dataset
    - Filtering is recommended for your own use
