The dataset was constructed by processing parliamentary proceedings using a robust alignment pipeline that handles diverse audio formats and non-verbatim transcripts. ### Dataset Summary - **Languages**: 22 European languages (see detailed breakdown below) - **Total aligned hours**: ~78,100 hours of initially aligned speech-text data - **Quality-filtered subsets**: - CER < 30%: approximately 61,000 hours - CER < 20%: approximately 50,500 hours (this is the primary subset provided directly through the Hugging Face Datasets interface for all languages) - CER < 10%: approximately 32,200 hours - **Domain**: Parliamentary proceedings (formal speaking style) - **Audio segment length**: Typically 3-20 seconds - **Format**: Audio segments with paired transcriptions ### Languages EuroSpeech provides substantial data for previously under-resourced languages: - 19 languages exceed 1,000 hours of data (CER < 20%) - 22 languages exceed 500 hours of data (CER < 20%) | Language | Code | Total Aligned (h) | CER < 30\% (h) | CER < 20\% (h) | CER < 10\% (h) | |------------------|------|-------------------|----------------|----------------|----------------| | Croatia | hr | 7484.9 | 5899.7 | 5615.8 | 4592.0 | | Denmark | da | 7014.2 | 6435.0 | 5559.8 | 3443.7 | | Norway | no | 5326.2 | 4578.8 | 3866.7 | 2252.2 | | Portugal | pt | 5096.3 | 4036.7 | 3293.5 | 2105.9 | | Italy | it | 4812.8 | 3539.6 | 2813.7 | 1767.3 | | Lithuania | lt | 5537.9 | 3971.0 | 2681.2 | 956.6 | | United Kingdom | en | 5212.2 | 3790.7 | 2609.3 | 1175.0 | | Slovakia | sk | 2863.4 | 2722.4 | 2553.6 | 2070.8 | | Greece | el | 3096.7 | 2717.6 | 2395.4 | 1620.9 | | Sweden | sv | 3819.4 | 2862.6 | 2312.8 | 1360.1 | | France | fr | 5476.8 | 2972.1 | 2249.8 | 1347.6 | | Bulgaria | bg | 3419.6 | 2570.4 | 2200.1 | 1472.8 | | Germany | de | 2472.2 | 2354.2 | 2184.4 | 1698.4 | | Serbia | sr | 2263.1 | 1985.1 | 1855.7 | 1374.1 | | Finland | fi | 2130.6 | 1991.4 | 1848.2 | 1442.2 | | Latvia | lv | 2047.4 | 1627.9 | 1218.8 | 499.9 | | Ukraine | uk | 1287.8 | 1238.3 | 1191.1 | 1029.8 | | Slovenia | sl | 1338.2 | 1241.7 | 1156.4 | 900.5 | | Estonia | et | 1701.1 | 1430.9 | 1014.9 | 382.5 | | Bosnia \& Herz. | bs | 860.2 | 781.9 | 691.3 | 447.8 | | Iceland | is | 1586.1 | 974.1 | 647.4 | 171.4 | | Malta | mt | 3281.6 | 1284.3 | 613.0 | 143.9 | | **Total** | | **78128.6** | **61006.4** | **50572.9** | **32255.5** | ## Dataset Structure ### Data Instances Each instance in the dataset consists of: - Audio segment (3-20 seconds) - Corresponding transcript text - Metadata including language, source session, alignment quality metrics ### Data Splits The dataset provides predefined train, development, and test splits for each language. To ensure data integrity and prevent leakage between sets, these splits are constructed by assigning entire parliamentary sessions (i.e., all segments derived from a single original long audio recording) exclusively to one of the train, development, or test sets. The exact proportions follow common practices (e.g., 80/10/10). ## Dataset Creation ### Source Data The data was collected from parliamentary proceedings across 22 European nations. Parliamentary sessions offer high-quality speech in a formal register, typically featuring clear speech with good audio quality and professional transcripts. ### Data Collection and Processing The dataset was constructed using a multi-stage pipeline: 1. **Data Sourcing and Metadata Collection**: Manual and scripted gathering of media/transcript links from parliamentary websites. 2. **Download Pipeline**: Automated retrieval of audio, video, and transcript files using specialized handlers for diverse source formats. 3. **Alignment Pipeline**: - Segmentation of long recordings into 3-20 second utterances using voice activity detection (VAD) - Transcription of segments using an ASR model to produce pseudo-labels - Alignment of segments to transcripts using a novel two-stage dynamic algorithm - Selection of best-aligned transcript formats and quality filtering 4. **Filtering**: CER-based filtering to create quality tiers (CER < 30%, < 20%, < 10%) ### Alignment Algorithm The core of the alignment process is a novel two-stage dynamic algorithm specifically engineered for extreme robustness when matching ASR pseudo-labels to noisy, non-verbatim parliamentary transcripts: 1. **Coarse stage**: Uses a sliding window to rapidly scan the transcript, efficiently bypassing large irrelevant sections to identify a set of top-k candidate text spans via Character Error Rate (CER). 2. **Fine-tuning stage**: Performs a local search around promising candidates, optimizing start position and window size for the best CER. A fallback mechanism restarts the search if no initial match meets a predefined quality threshold. ## Dataset Use ### Intended Uses The EuroSpeech dataset is intended for: - Training and evaluating automatic speech recognition (ASR) systems - Training and evaluating text-to-speech (TTS) systems - Multilingual speech research - Low-resource language speech technology development - Cross-lingual transfer learning in speech models ### Citation Information If you use this dataset, please cite: ``` [Citation details to be added upon publication] ``` ## Considerations ### Data Quality The dataset provides multiple quality tiers based on Character Error Rate (CER): - CER < 30%: More data, but potentially lower quality alignments - CER < 20%: Balanced quality-quantity trade-off (recommended for most applications) - CER < 10%: Highest quality alignments, but reduced quantity ### Licensing Information [License details to be added] ### Limitations - The dataset primarily represents formal parliamentary speech and may not generalize well to casual, spontaneous, or noisy speech environments. - The dataset reflects the demographics and speaking styles of European parliamentarians, which may not be representative of the general population. - Some languages have significantly more data than others, which could lead to performance disparities in multilingual models. ## Additional Information ### Dataset Curators - Samuel Pfisterer ([@SamuelPfisterer1](https://huggingface.co/SamuelPfisterer1)) - Florian Grötschla ([@FloGr](https://huggingface.co/FloGr)) - Luca Lanzendörfer ([@lucala](https://huggingface.co/lucala)) - Florian Yan ([@floyan](https://huggingface.co/floyan)) - Roger Wattenhofer ### Maintenance Status [Information about maintenance and update plans] ### Links - [EuroSpeech on Hugging Face Datasets](https://huggingface.co/datasets/disco-eth/EuroSpeech) - [EuroSpeech GitHub Repository](https://github.com/SamuelPfisterer/EuroSpeech)
