Research Projects

• Speech processors for combined electrical and acoustic hearing (2006-2009)
  A substantial number of cochlear implant users have considerable residual hearing in the unimplanted ear and recent studies have demonstrated that the use of a contralateral hearing aid often provides significantly improved speech perception, particularly in noise. The factors responsible for bimodal benefits are not well understood, though it appears likely that they result mostly from the provision of complementary information across modalities, rather than true binaural interactions. The proposed work will examine factors likely to be important in optimising the bimodal transmission of speech spectral information, focusing on three aspects of place-coding. This research will both clarify our understanding of factors underlying bimodal benefits and help to develop clinically applicable methods for optimally combining an implant and a contralateral hearing aid, thus providing a highly cost-effective way to improve everyday perceptual performance in many users of cochlear implants.
• Hearcom - Hearing in the communication society (2004-2009)
  HearCom is an integrated project under the FP6 ICT programme. It involves 30 partners from 12 countries and is coordinated by Tammo Houtgast and Marcel Vlaming from the VU University Medical Center in Amsterdam. Our society is strongly and increasingly communication-oriented. As much of this focuses on sound and speech, many people experience severe limitations in their activities, caused either by a hearing loss or by poor environmental conditions. The HearCom project aims at reducing these limitations in auditory communication.
• SYNFACE: Synthesised talking face derived from speech for hearing disabled users of voice channels (2001-2004)
  The main purpose of the SYNFACE project is to increase the possibilities for hard of hearing people to communicate by telephone. Many people use lip-reading during conversations, and this is especially important for hard of hearing people. However, this clearly doesn't work over the telephone!. This project aims to develop a talking face controlled by the incoming telephone speech signal. The talking face will facilitate speech understanding by providing lip-reading support. This method works with any telephone and is cost-effective compared to video telephony and text telephony that need compatible equipment at both ends.
• Acoustic and visual enhancement of speech for computer-based auditory training (2000-2003)
  Does seeing the speaker help in learning tricky aspects of a new language? A synthetic face is used to support modelling of troublesome phonetic gestures by second language learners
