| # KazMix-3 |
|
|
| Kazakh three-speaker overlapping-speech dataset for **target-speaker ASR (TS-ASR)**, released with the [Persona-ASR](https://github.com/IS2AI/Persona_ASR) project. Given a short **enrollment** utterance of a target speaker and a **3-speaker mixture**, the task is to transcribe only the target speaker, or reject the utterance when the target is absent. |
|
|
| This repository ships the **mixture manifests** and **generation scripts**, not the audio. Mixtures are derived from the **Kazakh Speech Dataset (KSD, [OpenSLR 140](https://www.openslr.org/140/))**; download KSD and run the scripts to reproduce the audio locally. |
|
|
| ## Splits |
|
|
| | Split | Total | Positive (target present) | Negative (target absent) | |
| |---|---|---|---| |
| | `train_clean_100` | 62,775 | 41,850 | 20,925 | |
| | `val` | 13,500 | 9,000 | 4,500 | |
| | `test` | 13,500 | 9,000 | 4,500 | |
|
|
| Positive trials contain the enrolled target speaker and carry its transcript; negative trials do not contain the target (the model should emit no target transcript). Speakers are disjoint across splits. |
|
|
| ## Files |
| - `train_clean_100_kazakh3mix_lufsfix_posneg.json`, `val_kazakh3mix_lufsfix_posneg.json`, `test_clean_kazakh3mix_lufsfix_posneg.json` |
| - `scripts/` — LUFS-uniform 3-speaker mixture generation (`rerender_kazakh3mix_lufs_uniform.py`) and manifest building. |
|
|
| ## Manifest fields |
| | Field | Description | |
| |---|---| |
| | `mixture_audio` | 3-speaker mixture (16 kHz) | |
| | `enrollment_audio` | Target-speaker enrollment utterance | |
| | `transcript` | Target reference transcript (empty for negatives) | |
| | `speaker_id`, `target_speaker_id`, `target_index` | Target identity and its source index in the mixture | |
| | `sample_type`, `class`, `label`, `is_target_present` | Positive/negative trial labels | |
| | `snr_db`, `lufs_per_source`, `clip_scale` | Mixing SNR and per-source loudness (LUFS-uniform) | |
| | `s1_path`, `s2_path`, `s3_path`, `source_speaker_ids`, `clean_source_rel` | Source provenance for regeneration | |
|
|
| The full field list is present in each JSON entry. |
|
|
| ## Mixing protocol |
| Three-speaker mixtures in the LibriMix `clean`/`max` style, loudness-normalized to a uniform LUFS across sources. Each mixture designates one target speaker; the enrollment is a *different* utterance from that speaker. |
|
|
| ## Regenerating the audio |
| 1. Download KSD from https://www.openslr.org/140/. |
| 2. Run `scripts/rerender_kazakh3mix_lufs_uniform.py`, pointing it at your local KSD path (see the [Persona-ASR repo](https://github.com/IS2AI/Persona_ASR) for full setup and dependencies). |
