面向藏语声纹识别的语料库建设

Corpus construction for Tibetan voiceprint recognition

藏语声纹识别技术的研究刚刚起步,建设一个用于藏语声纹识别的语料库迫在眉睫。结合藏语特点,设计、建立了一个面向藏语声纹识别的语料库。语料库包含文本相关、文本无关两部分,文本语料来自新闻报刊、文学类、教育类、科技类、佛学类、历史类和传统文化五明类等文献资料,录音者由来自多个不同藏语方言地区的50人组成,产生了语音语料9 500条,为藏语的声纹识别研究奠定了一定的基础。

Research on Tibetan voiceprint recognition technology has just started, and it is an urgent and necessary task to establish a corpus. We design and build a corpus based on the characteristics of Ti betan language, which consists of two parts.- text dependent part and text independent part. Texts of the corpus are collected from a variety of materials , including newspaper, literature, education, science and technology, Buddhism, and history and traditional culture. As for the recording part, we invite 50 speakers ftom different regions of Tibet. The corpus contains 9500 speech files and it lays a certain foun dation for Tibetan voiceprint recognition.
