-# Slovak Parliamentary ASR Corpus
-
-This dataset contains **aligned and segmented Slovak speech–text pairs** sourced from official plenary session recordings of the **Slovak National Council** (Národná rada Slovenskej republiky).  
-It was prepared by collecting raw audio from [MediaPortál NR SR](https://tv.nrsr.sk) and matching it with official full-text transcripts from the [Joint Czech and Slovak Digital Parliamentary Library](https://www.nrsr.sk/dl/).  
-A custom alignment and filtering pipeline segmented the recordings into **short clips (≤30 seconds)** with their corresponding transcriptions, producing a **2,806-hour ASR-ready dataset**.
-
-## 📌 Dataset Summary
-
-- **Total duration**: 2,806 hours  
-- **Number of segments**: 402,966  
-- **Average segment length**: ~25.1 seconds  
-- **Domain**: formal Slovak parliamentary speech  
-- **Use cases**: ASR model fine-tuning, speech research

-### 🔍 Field Descriptions
-
-- **`id`**: Unique integer identifier for the segment.  
-- **`start_time`**: Start timestamp (in seconds) within the original session recording.  
-- **`end_time`**: End timestamp (in seconds) within the original session recording.  
-- **`session_num`**: Parliamentary session number in the election term.  
-- **`snapshot`**: Date of the session.  
-- **`segment_number`**: Sequential index of the segment in the session.  
-- **`text`**: Slovak transcript (transcriber notes removed).  
-- **`duration`**: Segment duration in seconds.  
-- **`audio`**: Audio object containing local file path, waveform array, and sampling rate.

-## ⚙️ Processing & Alignment
-
-1. **Collection**  
-   - Audio scraped to `.mp3` format.
-   - Transcripts downloaded in `.docx` format.
-
-2. **Parsing**  
-   - Extracted speaker-segmented utterances.  
-   - Removed transcriber notes.
-
-3. **Alignment**  
-   - Matched words from the ground-truth transcript with a pseudo-labeled transcript generated from the audio.  
-   - **Assigned timestamps** to the matched words using the pseudo-labeled transcript, which had been force-aligned.
-
-4. **Segmentation**  
-   - Created segments ≤30 seconds based on the matched words.
-
-5. **Filtering**  
-   - Re-transcribed each segment. 
-   - Discarded any with WER > 40%.  
-   - Final dataset: 2,806 hours; 402,966 segments.
