| # Codeswitch Pairs LASE — Western held-out corpus | |
| 1043 held-out cross-script utterance pairs from 8 ElevenLabs Western Multilingual voices. Used to evaluate generalisation of speaker encoders trained on `Praxel/codeswitch-pairs-lase`. | |
| Each row is one synthesized utterance with metadata; pairs are reconstructed at evaluation time by joining on `voice_id` (same voice, different script = cross-script pair). | |
| ## Schema (manifest.jsonl) | |
| ```json | |
| { | |
| "voice_id": "21m00Tcm4TlvDq8ikWAM", | |
| "lang": "en | hi | te | ta", | |
| "text": "the prompt text", | |
| "wav_path": "<voice_name>/<lang>_NNN.wav", | |
| "quality": {"cosine": 0.97, "utmos": 4.6} | |
| } | |
| ``` | |
| Audio is 16 kHz mono WAV, ~2 s/utterance. | |
| ## Stats | |
| - **Pairs**: 1043 | |
| - **Voices**: 8 | |
| - **Languages**: en, hi, te, ta | |
| - **Quality gate**: WavLM-cosine ≥ 0.90 vs the voice's reference clip | |
| ## Provenance | |
| Synthesized using the [ElevenLabs Multilingual v2](https://elevenlabs.io) API. Voice IDs are public ElevenLabs catalog voices used under their TOS for research/evaluation purposes. Text prompts are short generic English phrases translated/transliterated into each target script. | |
