TCST-UT: Tibetan-Chinese speech translation dataset of Ü-Tsang dialect

This TCST-UT dataset contains 58767 samples, 72.08 hours, and audio files from 147 different speakers. Each sample is a triplet consisting of Tibetan speech, corresponding Tibetan text, and Chinese text. Among them, the Tibetan language speech data comes from the M2ASR Tibetan dialect speech recognition dataset, which is published on the m2sr.cslt.org website. The audio files can be obtained through email requests, so this dataset does not directly provide voice audio files, only the audio paths of the samples contained in the dataset. The audio path of each sample, along with the corresponding Tibetan text and Chinese translated text, is stored in the output. json file, where the audio path refers to the path in the public dataset.The size of output. json is 22MB. The file puts the audio path, Tibetan text, and Chinese translation text of each sample into a dictionary, with the data format being:Abbreviation of Name - Audio Number: {“audio”: Audio file path,“text”: {“Tibetan”: The Tibetan text corresponding to the audio file“Chinese”: The Chinese text corresponding to the audio file}}本TCST-UT数据集包含58767条样本，总时长72.08小时，音频数据来自147位不同的说话人。每条样本均为三元组结构，涵盖藏语语音、对应藏语文本以及中译本文本。其中，藏语语音数据源自M2ASR藏语方言语音识别数据集（M2ASR Tibetan dialect speech recognition dataset），该数据集发布于m2sr.cslt.org网站。音频文件需通过邮件申请获取，本数据集未直接提供语音音频文件，仅包含样本对应的音频路径。每条样本的音频路径、对应藏语文本与中译文本均存储于output.json文件中，此处的音频路径指公开数据集内的文件路径。output.json文件大小为22MB，该文件将每条样本的音频路径、藏语文本及中译文本整合为字典格式，数据结构为："名称缩写 - 音频编号": {"audio": "音频文件路径", "text": {"Tibetan": "该音频文件对应的藏语文本", "Chinese": "该音频文件对应的中译文本"}}
