| # PersonaMix |
|
|
| Controlled bilingual (Kazakh–English) benchmark for **target-speaker ASR** and **target-presence detection** on overlapping speech, released with [Persona-ASR](https://github.com/IS2AI/Persona_ASR). |
|
|
| Four speakers (two female, two male) each read 11 scripted sentences in **both Kazakh and English**. Mixtures span **1–3 interfering speakers** and SNRs of **−3, 0, +3, +6 dB**, under **same-language** (A) and **cross-language** (B) enrollment; the cross-language condition enrolls a speaker in one language and transcribes them in the other. |
|
|
| ## Structure |
| - `mixtures/` — overlapping-speech mixtures by condition: |
| - `A_samelang_{1,2,3}int/` — same-language enrollment, 1–3 interferers |
| - `B_crosslang_{1,2,3}int/` — cross-language enrollment, 1–3 interferers |
| - `experiment_jsons/` — evaluation manifests per condition and SNR: |
| - `*_asr.json` — target-speaker ASR (positive trials, with target transcript) |
| - `*_cls.json` — target-presence detection (positive + negative trials) |
| - `all_snr{-3,0,3,6}dB.json` — pooled manifests per SNR |
| - `ASR_88/` and `ASR_88 - {F1,F2,M1,M2}.csv` — the 88 source recordings (4 speakers × 11 sentences × 2 languages) and per-speaker scripts. |
|
|
| ## Manifest fields (`experiment_jsons/*.json`) |
| | Field | Description | |
| |---|---| |
| | `mixture_audio` | Overlapping mixture | |
| | `enrollment_audio` | Target-speaker enrollment utterance | |
| | `transcript` | Target reference transcript | |
| | `sample_type` | positive / negative (target present / absent) | |
| | `target_speaker` | Target speaker id (F1, F2, M1, M2) | |
| | `enrollment_lang`, `mixture_lang` | Enrollment vs. mixture language (equal = same-lang, differ = cross-lang) | |
| | `snr_db` | Target-to-interferer SNR | |
| | `enrollment_sentence`, `target_sentence`, `interferers` | Content and interference metadata | |
|
|
| ## Speakers |
| Four speakers, anonymized as F1 and F2 (female) and M1 and M2 (male). |
