Publication Title: Butler University Audio-Visual Database of Spoken Language, version 1

Authors: Carolyn Richie, Sarah Warburton, Megan Carter

Data type: Audio-Video

Data sources: Video data were recorded on August 10th, 13th, and 24th of 2007 for an investigation of lipreading ability. Participants read a series of prompts aloud and were recorded with a Panasonic DVC-80 digital video camera to miniDV digital video cassette tapes. Participants wore a Sennheiser MKE-2060 directional/cardioid lapel microphone throughout the recordings.

Project: The purpose of this corpus was to create an audio-video database of spoken language materials that could be used to investigate speech production and speech perception. The corpus contains audio-video files of fourteen talkers producing syllables, word lists, and sentences used in both academia and clinical settings.

Applications: We suggest that the corpus may be useful to researchers in a variety of disciplines. Linguists may find the corpus useful for studies of phonetics, phonology, and prosody of American English. Speech Scientists may find the corpus useful for investigations of motor speech production and auditory-visual speech perception. Engineers and Computer Scientists may find the corpus useful for investigations into Audio-Visual Speech Recognition (AVSR) by machines. Finally, Speech and Hearing Scientists may find the corpus useful for clinical purposes, such as the examination and improvement of speech perception by listeners with hearing loss. 

Languages: All audio-video files were recorded in American English.
