People
About the Speech and Hearing Science Research Group
Research focuses on the interface between basic and clinical issues
in speech communication, addressing both speech/language and auditory
impairments. The group provides theoretical and technical expertise as
a focus for collaborative research at UCL and beyond. Main foci are:
1) basic research into
phonetic representations of speech and their development in both first
and second languages;
2) translational research into auditory prostheses for speech
communication involving study of the receptive capacity of the impaired
auditory system for acoustic and electrical stimulation;
3) elucidating Auditory Processing Disorder (APD) in relation
to speech/language development and communication ability.
Stuart Rosen has brought theoretical insight and new research
techniques to
national and international collaborations in APD. His work on auditory
discrimination skills, and his collaboration with Sophie Scott on
rhythmic and nonverbal aspects of auditory perception, has provided new
grounds for exploring developmental language impairments. Andrew
Faulkner and
colleagues' cochlear implant work demonstrates perceptual adaptation to
the distortions of frequency-to-place mapping that arise in CI users,
and the limitations of current devices in signalling the pitch of
spectrally-varying sounds such as speech. Paul Iverson has established
a new
theoretical conceptualization of the acquisition of non-native speech
sounds which he is now applying to L2 training. Valerie Hazan's
ground-breaking
studies of talker variability revealed inter-listener differences in
the acoustic-phonetic determinants of speech intelligibility. She has
also led the international field in considering the role of
speechreading in the learning of non-native English contrasts. The
group has been awarded 10 project grants since 2001, of which 7
continue to 2009 and beyond, and staff have authored over 40 journal
articles, receiving over 450 citations.

Impact, applications, translational work and links with industry
Cochlear Implant research has generated invited presentations to
AAAS and NIH-funded meetings in the US, a highlight article in
Audiology Today (July 2004) and the recruitment of Faulkner and Rosen
as commentators for the forthcoming NICE review of the
cost-effectiveness of cochlear implants. Close links with the two
world-leading manufacturers (Cochlear & Advanced Bionics), who
employ 5 group alumni in research roles, provide research tools and
ongoing technical support. Faulkner leads a CEC Integrated Project
workpackage on hearing aid and cochlear implant fitting involving
Cochlear Europe, Amsterdam University Medical Centre (Dreschler),
Erasmus University Rotterdam (Verschuure), Oldenburg University
(Kollmeier), and the RNID (HEARCOM FP-004171).
Audiovisual speech synthesis: Faulkner co-established EU project
SYNFACE to develop and evaluate a system providing lipreading cues
supporting hearing-impaired use of the telephone. This collaboration
with Granström (KTH Stockholm), RNID, Instituut voor Doven (St
Michielsgestel, NL), and the international telecoms company Babel led
to a product launch in 2006 (the "Eyephone"). APD: Rosen contributes to
ASHA (American Speech-Language-Hearing Association) and British Society
of Audiology working groups on criteria for APD diagnosis.
