| # Scraped Bengali TTS Speech Chunks |
|
|
| Single-speaker Bengali (bn) speech chunks extracted from YouTube videos, |
| cleaned and segmented for TTS (text-to-speech) training data. |
|
|
| ## Pipeline |
|
|
| Each chunk was produced by: |
| 1. Downloading source audio via yt-dlp |
| 2. Trimming the first/last 2 minutes of each source video |
| 3. Removing background music/noise via Demucs vocal separation |
| 4. Splitting stereo channels into independent left/right tracks when present |
| 5. Voice Activity Detection (Silero VAD) to find speech regions per track |
| 6. Speaker diarization (pyannote.audio), run once on the full track; only |
| speaker turns with ZERO overlap against any other speaker are kept, then |
| intersected with the VAD speech regions -- chunk boundaries come from |
| these clean single-speaker windows, not from raw VAD segments, so |
| overlapping/crosstalk audio is excluded rather than merely down-weighted |
| 7. Emotion tagging (Hatman/audio-emotion-detection) on each accepted chunk -- |
| metadata only, nothing is filtered by emotion |
|
|
| ## Columns |

|
| - `audio`: the speech chunk, mono, 16kHz WAV |
| - `language`: ISO 639-1 language code (`bn` = Bengali) |
| - `seconds`: duration of the chunk in seconds |
| - `emotion`: predicted emotion label (Angry, Disgusted, Fearful, Happy, |
| Neutral, Sad, Suprised) from Hatman/audio-emotion-detection |
|
|
| ## Config |
