 ## 📖 Dataset Description / 数据集简介
 
-**WordVoice-5A** is a large-scale bilingual (Mandarin and English) dataset containing approximately **4.7k hours** of speech with fine-grained **word-level acoustic annotations**, designed for high-precision controllable Text-to-Speech (TTS). It addresses the scarcity of large-scale, high-quality word-aligned datasets with explicit acoustic annotations in the open-source community. Through a linguistically guided automatic annotation pipeline based on empirical acoustic distributions, the dataset provides five core acoustic attributes for each word: **Duration, Boundary, Energy, Pitch, and Tone**. It aims to break the "black-box" nature of LLM-based TTS and facilitate future research in fine-grained speech generation and acoustic modeling.

-**WordVoice-5A** 是一个约 **4.7k 小时**的大规模中英双语字/词级声学属性标注数据集，专为高精度、细粒度可控语音合成（TTS）设计。该数据集针对当前开源社区缺乏大规模、高质量字/词级对齐与显式声学标注数据的问题，提出了一套结合语言学规则与真实声学统计分布的自动化标注 Pipeline，为每个字/词提供 **时长（Duration）、边界（Boundary）、能量（Energy）、音高（Pitch）和音调（Tone）** 五维核心属性。WordVoice-5A 致力于打破 LLM-TTS 的"黑盒"特性，推动细粒度语音生成与声学建模研究。
