       MDSC 数据集包含 18,630 条录音，共 17 小时。其中，来自非构音障碍说话人的录音有 10,125 条（时长为 7.6 小时），来自构音障碍说话人的录音有 8,505 条（时长为 9.4 小时）。数据采集自 21 名构音障碍说话人（12名女性，9名男性）和 25 名非构音障碍说话人（13名女性，12名男性）。参与的构音障碍说话人符合以下特征：

       · 母语为普通话；

       · 年龄分布广泛（18至48岁），性别均衡；

       · 导致构音障碍的病因多样，包括脑性瘫痪、肝豆状核变性等。

       录音内容包括：10 个唤醒词，每个词以不同速度重复 5 次；以及 355 个非唤醒词，涵盖固定指令词、自由指令词、家居指令及其他短语，单人不重复文本为295条。所有录音均在安静的室内环境中进行，采样率为 16kHz。录音时，参与者位于移动麦克风前方约 20cm 处。

MDSC includes 18,630 recordings totaling 17 hours, of which 10,125 are from non-dysarthric recordings (Control) totaling 7.6 hours, and 8,505 are from dysarthric recordings (Dysarthria) totaling 9.4 hours. We record utterances from 21 dysarthric (12 females, 9 males) and 25 non-dysarthric (13 females, 12 males) speakers. The participants with dysarthric speakers have the following characteristics:

 • Native Mandarin speakers;
 • Broad age distribution (from 18 to 48) and gender balance
 • Diverse etiologies contribute to dysarthria, including cerebral palsy and hepatolenticular degeneration

The recordings consist of 10 wake-up words repeated five times at varying speeds. MDSC also includes 355 non-wake-up words, encompassing fixed command words, free command words, household instructions, and other phrases. The single person text list has 295 non-repeated sentences. The recordings, sampled at 16kHz, take place in a quiet indoor environment, with the participants positioned approximately 20cm away from the mobile microphone.

       LRDWWS 挑战赛旨在解决构音障碍人群的唤醒词检测任务，目标是推动该技术在现实应用中的使用落地。

      本次挑战赛的数据使用 MDSC 数据库作为训练集和开发集，并新增录制了包含 20 位构音障碍发音人的测试集 MDSC-Eval。MDSC-Eval 包含 8,760 条录音，总时长 9 小时。其录制方式与 MDSC 数据库保持一致，区别在于每位发音人额外录制了 11 个负例词，每个负例词朗读 3 遍。详情请参阅以下链接：https://lrdwws.org/

The LRDWWS Challenge is designed to tackle the wake-up word spotting task for individuals with dysarthria, with the ultimate goal of facilitating broader integration in real-world applications.

The challenge data uses the MDSC database as the training and development sets, and a new test set with 20 dysarthric was recorded, named MDSC-Eval. MDSC-Eval includes 8,760 recordings totaling 9 hours. The recording method for the MDSC-Eval is consistent with the MDSC, with the difference being that single person in the set has 11 additional negative words, with each negative word read 3 times.
