GenSEC-LLM/SLT-Task2-Post-ASR-Speaker-Tagging

Dataset Name: Dataset for ASR Speaker-Tagging Corrections (Speaker Diarization)

Description

• This dataset is pairs of erroneous ASR output and speaker tagging, which are generated from a ASR system and speaker diarization system. Each source erroneous transcription is paired with human-annotated transcription, which has correct transcription and speaker tagging.
• SEGment-wise Long-form Speech Transcription annotation (SegLST), the file format used in the CHiME challenges

Example) session_ge1nse2c.seglst.json

Structure

Data Split

The dataset is divided into training and test splits:

• Development Data: 142 entries
  • 2 to 4 speakers in each session
  • Approximately 10 ~ 40 mins of recordings
• Evaluation Data: 104 entries
  • 2 to 4 speakers in each session
  • Approximately 10 ~ 40 mins of recordings

Keys (items)

• session_id: "session_ge1nse2c",
• words: Transcription corresponding to the time stamp (start, end).
• start_time: Start time in second.
• end_time: End time in second.
• speaker: Speaker tagging in string "speaker<N>"

Source Datasets

err_source_text: This is the erroneous ASR-Diarization results to be fixed. Has dev, eval folders ref_annotated_text: This is the human annotated ground-truth for evaluation. Only dev split is included.

• Development Sources:

  • dev: 142 sessions

• Evaluation Sources:

  • eval: 104 Sessions

Access

The dataset can be accessed and downloaded through the HuggingFace Datasets library.

Evaluation

This dataset can be evaluated by MeetEval Software

From PyPI

pip install meeteval

From source

git clone https://github.com/fgnt/meeteval
pip install -e ./meeteval

Evaluate the corrected segLST files:

python -m meeteval.wer cpwer -h err_source_text/dev/session_ge1nse2c.json -r ref_annotate_text/dev/session_ge1nse2c.json

Or after installation, you can use the following command alternatively.

meeteval-wer cpwer -h err_source_text/dev/session_ge1nse2c.json -r ref_annotate_text/dev/session_ge1nse2c.json
