RLE Biography |
Joe
Perkell and his colleagues are conducting a series
of experiments to explore the control and coordination
of speech articulatory movements. A system for electromagnetic
midsagittal articulometry has been developed and is used
to characterize the various articulator motions under
study. Dr. Perkell also collaborates with other scientists
to study the influence of hearing on the speech production
of cochlear implant patients and on mechanisms underlying
certain kinds of voice disorders. |

RLE Biography |
Principal Research Scientist Stefanie
Shattuck-Hufnagel investigates the cognitive structures
and processes involved in speech production planning,
particularly at the level of speech sound sequencing.
Her work with speech error patterns and with the acoustic
analyses of prosody has implications for cognitive models
of speech production and for phonological theory, as well
as applications in speech recognition and synthesis. |

RLE Biography |
Kenneth
N. Stevens is a principal investigator in the Speech
Communication Group of the Research Laboratory of Electronics.
Dr. Stevens, who received the Sc.D. in electrical engineering
from MIT and bachelor's and master's degrees in engineering
physics from the University of Toronto, has pioneered
contributions to the theory, mathematical methods and
analysis of acoustics in speech production, leading to
the contemporary foundations of speech science. His research
in speech production, speech perception and speech synthesis
has spanned a period of 40 years. Professor Stevens is
especially known for his work on modeling of sound production
in the larynx and the human vocal tract and on the relation
between these models and linguistic representation of
speech. Many of the leading speech scientists throughout
the world have been Prof. Stevens' students or post-doctoral
fellows, or have sought out sabbaticals in his laboratory.
Stevens' laboratory has been referred to by colleagues
as a "national treasure." |

Margaret
Denny received her Ph.D. in Speech Science from
Purdue University; she has been a post-doctoral fellow
at Dartmouth Medical School, and has taught in the Communication
Disorders Department at Boston University. Her research
interests include the effects of hearing on adult speech
production and the control of speech breathing. |

Satra's Homepage |
Satrajit
Ghosh is a Cognitive Neuroscientist with formal
training in computer science, computational modeling
of brain function and medical imaging. His research
focuses on understanding the cognitive processes related
to speech production and perception using a combination
of functional brain imaging, computational modeling
and psychophysical experiments. His current work involves
fMRI experiments aimed at exploring brain function when
somatosensory and auditory feedback is perturbed artificially
while speaking. While a doctoral student in the Department
of Cognitive and Neural Systems at Boston University
his research was concerned with modeling speech motor
control in the presence of sensory feedback delays and
establishing an experimental setup for investigation
of speech with fMRI. |

617.253.0566—Tel
Room 36-585 |
Helen
Hanson received her Ph.D. in Engineering Sciences
from Harvard University in 1995 and did a postdoctoral
fellowship at the MIT Speech Communication Group from
1995-1998. After working at Sensimetrics Corp. for four
years, she returned to MIT as a Research Scientist. Her
research is geared towards the design of a high-quality
speech synthesis system based on formant synthesis. Currently,
she is examining the interaction of prosody and physiology,
and details of stop consonant production. |

Miwako
Hisagi received her Ph.D. in Speech and Hearing Sciences
from the City University of New York (CUNY) - Graduate Center (GC).
While there, she worked as a Research Assistant at the Speech
Acoustic and Perception Lab (SAPL) and the Developmental
Neurolinguistics Lab (DNL). She also graduated from George Mason
University (VA) with an M.A. in English (Linguistics) and a graduate
certificate in Teaching English as a Second Language (TESL). Her
research interests are cross-linguistic speech production and
perception and the Event-Related Potentials (ERPs) study in speech
perception. She is currently involved with the speech perception
and production project for cochlear implant patients. |

Sharon
Manuel is a Phonetician, with formal training in
Anthropology, Speech Pathology, and Linguistics. While
a doctoral student at Yale University, she worked as a
Research Assistant at Haskins Laboratory, and spent a
year in Zimbabwe. She did her postdoctoral work in the
Speech Group at MIT. Her current research interests include
production, acoustics, and perception of casual speech,
and related issues of lexical access. |

Melanie
Matthies is also an Associate Professor in the
Communication Disorders program of the Department of Health
Sciences at Boston University. She completed a Ph.D. at
the University of Illinois at Urbana/Champaign in Hearing
Science and an M.S. in Audiology from Purdue. Prof. Matthies
is currently serving as section editor in the area of
"Cochlear Implants and Aural Rehabilitation"
for the Ear and Hearing journal, and her primary research
interest is the effect of hearing status on speech production. |

Room 36-547 |
Mark
Tiede completed undergraduate and graduate study in Linguistics
at Yale, separated by four years as a Navy Electronics
Technician, and two years assembly coding microprocessors.
He was invited to join Haskins Laboratories as a programmer
and research assistant. He was recruited from there to
participate for six years in the Human Information Processing
group of the Advanced Telecommunications Research laboratories
in Kyoto, Japan. He joined RLE after returning to the
U.S. in 1999, and currently divides his time between the
Speech Communication group and Haskins. Mark’s research
interests are focused on techniques for studying speech
production, and the integration of such data into improved
models of articulatory speech synthesis. Mark is married,
with two children, and enjoys recreational cycling, juggling,
and ragtime piano. |

Seth
Hall has managed the computer systems used by
several groups within the Research Laboratory of Electronics
since he came to MIT in 1988. These groups currently

the Remote Sensing and Estimation Group (rseg.mit.edu),
and the MIT Venture Mentoring Service (web.mit.edu/vms).
His responsibilities include planning, acquisition,
installation, and maintenance of the server and desktop
systems used by these groups, as well as the day-to-day
operation and management of these servers and systems.
In addition, Seth provides general consulting to faculty,
staff, and students on topics ranging from programming,
data analysis and visualization, and real time data
acquisition, to new equipment needs planning and installation,
network utilization, data backup and recovery, and more
or less anything else that he happens to be asked to
do.
