MODALITY corpus - SPEAKER 36 - SEQUENCE S1

The MODALITY corpus is one of the multimodal database of word recordings in English. It consists of over 30 hours of multimodal recordings. The database contains high-resolution, high-framerate stereoscopic video streams and audio signals obtained from a microphone array and a laptop microphone. The corpus can be employed to develop an AVSR system, as every utterance was labelled. Recordings in noisy conditions can be used to test the robustness of speech recognition systems. The language material was based on a remote control scenario and it includes 231 words -numbers, names of months and days, a set of verbs and nouns related to a computer device control. They were read by speakers as separated words and sequences resulting in a set of 12 recording sessions per speaker. Half of the sessions were recorded in quiet conditions, the other half contained three kinds of intrusive signals (traffic, babble and factory noise). The corpus includes recordings of 42 speakers (33 male, 9 female). The participants include 20 students and staff of Multimedia Systems Department of the Gdańsk University of Technology, 5 students of the Institute of English and American Studies of the University of Gdańsk, and 17 native English speakers. The dataset consist of recordings and visual features for SPEAKER 36: sex: man native speaker: yes age: 30 The test material: SEQUENCE S1 All recordings for all speakers are available at http://www.modality-corpus.org/ Sample still from the corpus(SPEAKER 36) Due to the size of the corpus (approx. 2.5 TB of data), every speaker’s recording was placed in a separate zip file of the size approx. 4-7 GB each. The recordings were organized according to the speakers’ language skills. The group A (17 speakers) consists of native-speakers. Non-native speakers recordings (Polish nationals) were placed in the Group B (25 speakers). The audio files use the Waveform Audio File Format (.wav), and contain a single PCM audio stream sampled at 44.1 kSa/s with 16-bit depth. The video files utilize the Matroska Multimedia Container Format (.mkv) in which a video stream in 1080p resolution, captured at 100 fps was placed after being compressed with h.264 codec (using High 4:4:4 profile). The ‘.lab’ files are text files containing the information on word positions in audio files, and follow the HTK label format. Each line of a ‘.lab’ file contains the actual label preceded by start and end times (in 100 ns units) e.g. : 1239620000 1244790000 FIVE which denotes the word “five”, occurring between the 123.962 s and 124.479 s of audio.Word-accurate SNR values calculated for every recording are also included in the ZIP file.MODALITY语料库（MODALITY Corpus）是一款英语单词录音类多模态数据库，共计收录超过30小时的多模态录音数据。该数据库包含高分辨率、高帧率立体视频流，以及由麦克风阵列与笔记本电脑麦克风采集的音频信号。由于所有语音片段均已完成标注，该语料库可用于开发音视频语音识别（Audio-Visual Speech Recognition, AVSR）系统；带噪环境下的录音可用于测试语音识别系统的鲁棒性。其语言素材基于遥控器操控场景，涵盖231个单词——包含数字、月份与星期名称，以及一组与计算机设备操控相关的动词与名词。参与者需朗读单个单词及单词序列，每位参与者需完成12次录音会话，其中6次于安静环境中录制，剩余6次则混入了三类干扰信号：交通噪声、人声嘈杂声与工厂背景噪声。该语料库共收录42名参与者的录音，其中男性33名、女性9名。参与者群体包括：格但斯克理工大学多媒体系统系的20名学生与教职工、格但斯克大学英美研究学院的5名学生，以及17名以英语为母语的人士。数据集包含36号参与者的录音与视觉特征：性别为男性，母语为英语，年龄30岁。测试素材为序列S1。所有参与者的全部录音均可在http://www.modality-corpus.org/获取。语料库样帧（36号参与者）。鉴于该语料库总数据量约2.5 TB，每位参与者的录音均打包为单独的ZIP压缩包，单包大小约4~7 GB。录音按参与者的语言能力分为两组：A组（17人）为以英语为母语的参与者；B组（25人）为非母语参与者，均为波兰籍人士。音频文件采用波形音频文件格式（Waveform Audio File Format, .wav），包含单路PCM音频流，采样率为44.1 kSa/s，位深度为16比特。视频文件采用Matroska多媒体容器格式（Matroska Multimedia Container Format, .mkv），其中封装了经h.264编解码器（采用High 4:4:4 profile配置）压缩的1080p分辨率视频流，采集帧率为100 fps。.lab文件为文本文件，用于记录音频文件中的单词位置信息，遵循HTK标注格式（HTK Label Format）。.lab文件的每一行均包含单词标注内容，其前为起始与结束时间戳（单位为100纳秒），示例如下：1239620000 1244790000 FIVE，该示例表示单词"five"出现在音频的123.962秒至124.479秒区间内。此外，ZIP压缩包中还包含了每条录音的逐词信噪比（Signal-to-Noise Ratio, SNR）计算值。
