+<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
