i4ds/spc_r_segmented

Diarized and segmented speech dataset derived from 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 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

from datasets import load_dataset

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