  We present the Tongue and Lips corpus (TaL), a multi-speaker corpus of audio,
ultrasound tongue imaging, and lip videos. TaL consists of two parts: TaL1 is a
set of six recording sessions of one professional voice talent, a male native
speaker of English; TaL80 is a set of recording sessions of 81 native speakers
of English without voice talent experience. Overall, the corpus contains 24
hours of parallel ultrasound, video, and audio data, of which approximately
13.5 hours are speech. This paper describes the corpus and presents benchmark
results for the tasks of speech recognition, speech synthesis
(articulatory-to-acoustic mapping), and automatic synchronisation of ultrasound
to audio. The TaL corpus is publicly available under the CC BY-NC 4.0 license.
