New publications: 

(1) UCLA Variability Speaker Database was developed by UCLA Speech Processing and Auditory Perception Laboratory and is comprised of approximately 34 hours of English speech and orthographic transcripts. Speakers (101 female, 101 male) took part in six tasks: vowel sounds, reading sentences, giving instructions, neutral conversation, happy conversation, a phone conversation, annoyed conversation, and responding to a video. This corpus was designed to sample variability in speaking within individual speakers and across a large number of speakers.  


UCLA Variability Speaker Database is distributed via web download.   


2021 Subscription Members will automatically receive copies of this corpus. 2021 Standard Members may request a copy as part of their 16 free membership corpora. Non-members may license this data for a fee.

(2BOLT Egyptian Arabic Treebank – SMS/Chat was developed by LDC and consists of Egyptian Arabic SMS/Chat data with part-of-speech annotation, morphology, and syntactic tree annotation. This release contains 349,414 tokens before clitics were split and 435,677 tree tokens after clitics were split for treebank annotation. The source data was collected by LDC from its collection platform or by donation and was manually reviewed to exclude material not in the target language or with sensitive content. Originally written in Arabizi (Romanized/Latin characters) script, the source SMS/chat text was transliterated to Arabic script and manually corrected prior to treebank annotation. Annotations followed Penn Arabic Treebank guidelines.
