Audiovisual project

What is the role of face and voice information in speech communication?

UZH researchers are about to find out

Would you like to be involved? 

                 

 

Description

Goals:  The Phonetics and Speech Science Group of the University of Zurich is currently investigating the role of expressive audio-visual information on speaker and speech recognition, with the goal of obtaining a better understanding of the mutual contribution of face and voice cues in speech communication.

Participants:  We are looking for mothers who:

  • are natives of British or American English, or High German
  • have typical hearing and vision (no glasses)
  • have typical speech and language development
  • have babies between 6 and 8 months

Eligible candidates will be asked to submit a voice recording for accent-screening purposes.

Recording sessions: Mothers will be audio and video recorded while performing semi-spontaneous speech tasks (e.g. reading stories, describing maps, giving instructions) in the presence of their babies and of an adult. The presence of an accompanying person, caring for the child, is requested for the entire duration of the recording sessions. The recordings will take place in Zurich at the Speech Laboratory of the Linguistic Research Infrastructure (LiRI). The tasks involving the mothers and their children will be performed in both same and separate recording booths which, however, allow for visual and auditory contact between participants.  Auditory stimuli from the mothers will be the object of acoustic analysis. Audiovisual stimuli from the mothers will be subsequently employed as input for online perceptual experiments.

IMPORTANT: Casual recordings of children's vocalizations will be permanently deleted.
