# i4ds/spc_r_segmented

Diarized and segmented speech dataset derived from [i4ds/spc_r](https://huggingface.co/datasets/i4ds/spc_r).

## Description

Each row is a merged speech segment belonging to a single speaker. The source audio and SRT subtitles from `i4ds/spc_r` were processed with the following pipeline:

1. **Diarization** -- [pyannote/speaker-diarization-3.1](https://huggingface.co/pyannote/speaker-diarization-3.1) assigned speaker labels to each SRT segment based on temporal overlap.
2. **Merging** -- Consecutive SRT segments from the same speaker were merged when the silence gap between them was below a threshold (default 1.0s) and the resulting duration stayed within bounds (default 10--20s).
3. **Slicing** -- The merged time ranges were used to slice the original audio waveform. Each segment is encoded as FLAC.

## Columns

| Column     | Type    | Description                                      |
|------------|---------|--------------------------------------------------|
| `id`       | string  | Unique identifier (`row{NNNNN}_seg{NNN}`)        |
| `duration` | float64 | Segment duration in seconds                      |
| `audio`    | audio   | FLAC audio for the segment                       |
| `text`     | string  | Merged transcript text from the SRT segments     |

## Usage

```python
from datasets import load_dataset

ds = load_dataset("i4ds/spc_r_segmented")
print(ds["train"][0])
