We present the Tongue and Lips corpus (TaL), a multi-speaker cor-pus 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; TaL80is a set of recording sessions of 81 native speakers of English with-out voice talent experience. Overall, the corpus contains 24 hours ofparallel 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 availableunder the CC BY-NC 4.0 license.
