LifeLUCID Corpus: Recordings of Speakers Aged 8 to 85 Years Engaged in Interactive Task in the Presence of Energetic and Informational Masking, 2017-2020

This speech corpus contains recordings for 104 monolingual native southern British English speakers aged between 8 and 85 years old while they engaged in a problem-solving picture-based ‘spot the difference’ task (Diapix) with a conversational partner in four listening conditions. In NORM (quiet, no masking), participants heard each other normally. In SPSN (speech-shaped noise), participants communicated in speech shaped noise at an approximate signal-to-noise ratio of 0 dB. In IMRE (informational masking related picture), they communicated while three voices in the background talked about the same picture. In IMUR (information masking unrelated picture), they communicated while three voices in the background talked about a different Diapix picture. Participants were recorded in sex and age band matched pairs; they were unfamiliar with one another. They were seated in separate sound-treated booths and communicated via headphones. One participant in the pair took the lead in the interaction and participants switched roles, each completing four conditions in each role. For each recording, there is a stereo audio file (.wav format) with each participant on a separate channel and two textgrid files, with time-aligned orthographic transcripts for each of the participants.本语音语料库收录了104名单语母语英国南部英语使用者的录音数据，这些参与者年龄介于8至85岁之间。他们在四种聆听条件下，与对话伙伴共同完成基于图片的‘找不同’解题任务（Diapix）。其中，在NORM（安静无掩蔽）条件下，参与者可正常聆听彼此的对话；在SPSN（语音形状噪声）条件下，参与者需在近似0分贝信噪比的语音形状噪声环境中完成交流；在IMRE（信息掩蔽相关图片）条件下，背景中有三个声音在讨论同一张Diapix图片，参与者需在此场景下完成交流；在IMUR（信息掩蔽无关图片）条件下，背景中有三个声音在讨论另一张不同的Diapix图片，参与者需在此场景下完成交流。所有参与者均按性别与年龄组匹配成对，且彼此互不熟识。他们分别坐在独立的声学隔音舱内，通过头戴式耳机进行交流。每对参与者中一人将主导互动过程，随后双方交换角色，每名参与者需在两种角色下各完成四种聆听条件的测试。每份录音均对应一个双声道音频文件（格式为.wav），两个声道分别收录一名参与者的语音；同时附带两个TextGrid文件，分别为两名参与者的时间对齐正字法转录文本。
