| # WTFO Code-Switching Speech | |
| Code-switching speech dataset prepared for automatic speech recognition training. | |
| ## Dataset fields | |
| - `audio`: self-contained 16 kHz mono PCM16 FLAC bytes using the Hugging Face `Audio` feature | |
| - `text`: transcript | |
| - `duration`: audio duration in seconds (`float64`) | |
| ## Split summary | |
| - Split: `train` | |
| - Examples: 98,662 | |
| - Total duration: 567422.698 seconds (157.62 hours) | |
| The Parquet shards embed the audio bytes. They do not depend on the original local file paths. | |
| ## JSONL manifest | |
| `metadata/text_audio_pairs.jsonl` contains `text`, `audio_filepath`, `duration`, and `lang`. All rows use `lang: "<|NAN|>"`. | |
