Designed for the acquisition of acoustic-phonetic knowledge and for the development and evaluation of automatic speech recognition systems, it contains recordings of 630 American English speakers each reading 10 phonetically rich sentences, for a total of 6300 utterances comprising 2342 distinct sentences. Data collection and annotation were a joint effort by Texas Instruments, the Massachusetts Institute of Technology, and SRI International, and the data release was prepared by NIST (National Institute of Standards and Technology). TIMIT was among the first publications that appeared with the launch of LDC's catalog in 1993. It remains one of the Consortium's top ten distributed corpora and may be the single most widely-used speech database. Despite its age and small size relative to modern data sets, TIMIT's wide range of phonetically-representative inputs, its time-aligned lexical and phonemic transcripts, and its easy availability through the LDC Catalog have contributed to its widespread use and continued popularity. Thousands of researchers remember its famous first sentence: "she had your dark suit in greasy wash water all year". LDC continues the TIMIT series with its Global TIMIT project which aims to create a series of corpora in a variety of languages with TIMIT-like features. (Chanchaochai et al., 2018). Data sets published from that project include: Global TIMIT Learner Treebank English, Global TIMIT Learner Simple English, Global TIMIT Mandarin Chinese - Guanzhong Dialect, and Global TIMIT Mandarin Chinese. The LDC Catalog features over 900 holdings in more than 90 languages and more data is added each year. All TIMIT corpora are available for licensing by Consortium members and non-members.

The DIHARD second development and evaluation sets were drawn from diverse sources including monologues, map task dialogues, broadcast interviews, sociolinguistic interviews, meeting speech, speech in restaurants, clinical recordings, extended child language acquisition recordings, and web videos. Annotations include diarization and segmentation. Second DIHARD Challenge Evaluation - Eleven Sources is distributed via web download. 2022 Subscription Members will automatically receive copies of this corpus. 2022 Standard Members may request a copy as part of their 16 free membership corpora.
