EuroSpeech Data Sources

This repository contains the source metadata for the EuroSpeech multilingual speech dataset. EuroSpeech is a large-scale parliamentary speech corpus covering 22 European languages with over 78k hours of aligned speech-text data.

📋 Repository Contents

This repository provides comprehensive CSV files that document the original sources for all audio and transcript data used in the EuroSpeech dataset. For each of the 22 countries included in EuroSpeech, we maintain detailed metadata files containing:

• Video/Audio URLs: Direct links to parliamentary recordings
• Transcript URLs: Links to corresponding transcript documents
• Session metadata: Parliamentary session identifiers and additional context

🔗 Relationship to EuroSpeech Dataset

The main EuroSpeech dataset is available at: disco-eth/EuroSpeech

Each audio segment in the main EuroSpeech dataset contains video_id and/ or transcript_id fields that can be cross-referenced with the CSV files in this repository to trace back to the original parliamentary source URLs. This provides complete transparency and enables researchers to:

• Verify the provenance of specific data points
• Understand the original context of parliamentary sessions
• Replicate or extend the data collection methodology

📁 File Structure

The CSV files vary significantly in structure across different parliaments. Each country's CSV reflects the specific data available from their parliamentary systems:

Core Identifier Fields:

• video_id - Unique identifier for video/audio (always present)
• transcript_id - Unique identifier for transcript (when available; otherwise video_id serves for both)

URL Fields (examples from actual implementation):

Video/Audio Sources:

• mp4_video_link, youtube_link, m3u8_link, mp3_link
• generic_video_link, generic_m3u8_link, processed_video_link

Transcript Sources:

• pdf_link, html_link, dynamic_html_link, doc_link
• processed_transcript_html_link, processed_transcript_text_link

Subtitle Sources:

• srt_link

Metadata Fields:

• Highly variable across parliaments
• May include dates, session information, titles, etc.
• Structure and availability depend entirely on what each parliament provides

Example CSV structure:

video_id,mp4_video_link,doc_link,processed_transcript_html_link
12345,https://example.com/video/12345.mp4,https://example.com/transcript/12345.docx,https://example.com/transcript/12345

Note: While the examples above show the supported column types from our pipeline, the actual column names and available fields vary by parliament, even thought the url fields should always be a subset of the provided ones.
