| <h1 align="center">X-Voice Multilingual Test Set</h1> |
| <h3 align="center">High-Fidelity Test Set for Multilingual Text-to-Speech across 30 Languages</h3> |
|
|
|
|
| This test set is built as part of the research: **X-Voice: One Speaker, 30+ Languages with Zero-Shot Voice Cloning**, serving as the evaluation benchmark for our model. |
|
|
| ## Dataset Summary |
| - **30 languages** |
| - **European**: bg (Bulgarian), cs (Czech), da (Danish), de (German), el (Greek), en (English), es (Spanish), et (Estonian), fi (Finnish), fr (French), hr (Croatian), hu (Hungarian), it (Italian), lt (Lithuanian), lv (Latvian), mt (Maltese), nl (Dutch), pl (Polish), pt (Portuguese), ro (Romanian), ru (Russian), sk (Slovak), sl (Slovenian), sv (Swedish). |
| - **Asian**: id (Indonesian), ja (Japanese), ko (Korean), th (Thai), vi (Vietnamese), zh (Chinese). |
| - **500 utterances per language** from **over 100 speakers** (15,000 utterances in total). |
| - Audio format: **24kHz mono WAV**. |
| - Each sample includes human-recorded **ground-truth audio**. |
| - Primarily constructed from **Common Voice**. Vietnamese data from Dolly-Audio, Korean from Emilia, Croatian from ParlaSpeech-HR. |
|
|
| ## Curation Pipeline |
| 1. Temporal and speaking rate filtering |
| 2. Silero VAD for speech segmentation and silence trimming |
| 3. ECAPA-TDNN speaker verification (cosine similarity ≥ 0.6) to ensure consistent speakers between prompt and reference audio |
|
