TIDIGITS

<p>This&nbsp;corpus&nbsp;contains speech which was originally designed and collected at Texas Instruments, Inc. (TI) for the purpose of designing and evaluating algorithms for speaker-independent recognition of connected digit sequences. There are 326 speakers (111 men, 114 women, 50 boys and 51 girls) each pronouncing 77 digit sequences. Each speaker group is partitioned into test and training subsets.</p><br>
<p>The corpus was collected at TI in 1982 in a quiet acoustic enclosure using an Electro-Voice RE-16 Dynamic Cardiod microphone, digitized at 20kHz. The waveform files are in the NIST SPHERE format.</p><br>

<p>As of April, 2015, TIDIGITS is also available in flac compressed wav. This package is available to licensees as an additional download. Not included in this version are the folders relating to handling the shortened sphere files of the original corpus.</p></br>

背景概述

TIDIGITS是一个用于说话者无关连续数字序列识别算法设计和评估的语音数据集，包含326位说话者（分为男、女、男孩和女孩四组）的77个数字序列发音，分为测试和训练子集。数据于1982年在安静环境中采集，采样率20kHz，原始格式为NIST SPHERE，2015年起还提供了flac压缩wav格式。
