该数据集提供了一个独特的15年纵向声学记录，追踪了一位普通话专业电视主持人从35岁到50岁（2012-2026年）的声音老化过程。数据集包含从广播访谈和节目中提取的高质量音频，捕捉了中年声音成熟过程中微妙的生理和韵律变化。数据以高保真.wav文件和详细注释的.csv元数据形式呈现，包含多层标签，如结构性停顿、认知填充词和词汇重音。数据集还提供了一个基于浏览器的可视化工具，用于分析15年时间跨度的韵律流和节奏密度。该语料库为临床声音老化研究、社会语言学分析和年龄适应性AI声音合成开发提供了强有力的资源。

This dataset provides a unique 15-year longitudinal acoustic record tracking the vocal aging of a professional Mandarin-speaking television host from age 35 to 50 (2012–2026). Comprising high-quality audio extracted from broadcast interviews and programs, the collection captures the subtle physiological and prosodic transitions inherent in middle-aged vocal maturation. The data is structured as high-fidelity .wav files paired with meticulously annotated .csv metadata, featuring multi-layered tagging for structural pauses, cognitive fillers, and lexical stress. To facilitate data exploration, a built-in browser-based visualizer is included, providing a color-coded interface to analyze prosodic flow and rhythmic density across the 15-year span. This corpus serves as a robust resource for clinical voice aging research, sociolinguistic analysis, and the development of age-adaptive AI vocal synthesis.
