CCRMA HEARING SEMINAR
on Thursday, 13 June 2002, 11:00am
CCRMA Library, The Knoll
http://mambo.ucsc.edu/psl/ccrmas/ccrmas.html
There will be a phonetics-related talk at the Hearing Seminar this
week.
At the last Hearing Seminar we heard how a new model of speech helped
predict pronunciation variations. This week we hear how a better
description of the underlying state variables helps us model
co-articulations and improve speech recognition.
The conventional approach to speech recognition uses hidden Markov
models, which model the observed speech with a discrete set of
"states". Our speakers this week, Joe Frankel and Simon King, argue
that a continuous state model, the Kalman filter, is a better way to
model (and recognize) speech.
This talk is sponsored by Ed Flemming in the Linguistics Department at
Stanford.
See you all at CCRMA. Bring your favorite articulators and we'll have
a good discussion!

Speech recognition using linear dynamical models
Joe Frankel & Simon King
The Centre for Speech Technology Research
University of Edinburgh
http://www.cstr.ed.ac.uk/
We will be talking about ongoing work in which we are exploring an
alternative to the Hidden Markov Model for speech recognition. Our
work was initially motivated by looking at speech production,
particularly new articulatory measurement data collected by Alan
Wrench ( http://sls.qmced.ac.uk/dept/awrench/home.htm ) which
illustrates that the underlying production mechanism is a continuous
one which makes smooth trajectories in a (hidden) space of articulator
settings. We also show that a linear, Markovian model is appropriate
for acoustic-only speech data.
We have therefore been experimenting with a model for speech
recognition which has these properties: the linear dynamical system
model, also known as a Kalman filter. This simple model has a
continuous hidden state (whereas the HMM has a discrete hidden state)
and we believe this gives it the potential to outperform HMMs.We will
describe how the model is trained and used for recognition and present
a set of experimental results on the TIMIT database. We will also
describe how we intend to extend the power of the model and give some
results for some recent pilot experiments.
The main purpose of our visit is to discuss collaboration with CSLI
and other researchers in the area, so we hope for plenty of feedback
and discussion!

The six Reuters Foundation Digital Vision fellows will each give a
short overview of the project they have developed during their stay at
CSLI this past academic year.

of their projects: http://reuters.stanford.edu/current_fellows.html
Note that this Coglunch is brownbag, no pizza or sandwiches will be
available at the door.

PARC FORUM
on Thursday, 13 June 2002, 4:00pm - 5:00pm
George Pake Auditorium, PARC

Adventures at the Interface:
User Experience Technology, Techniques, Transfer & Futures
Daniel M. Russell
Senior Manager, User Sciences & Experience Research (USER)
IBM Almaden Research Center
One moment of a single user test at PARC in 1983 determined what I'd
be doing for the next 19 years: designing, creating and developing
user experiences in the computational medium. I believed my career
would be in artificial intelligence, but that afternoon lead to a
crisis in faith and my conversion experience to UE. I'll then
fast-forward to how the USER Lab at IBM Almaden's lab is currently
advancing the user experience in the areas of UE technology, methods
and transfers. The talk winds up with some cross-cultural analysis
synthesizing experiences at three different research labs -- PARC,
Apple and IBM. Key concepts: UE is amazingly difficult, for all the
wrong reasons; how I learned to stop worrying and love big problems;
effective transfer of technology; why UE will dominate future product
development.
About the speaker: Daniel Russell is the Senior Manager of the User
Sciences & Experience Research (USER) lab at IBM's Almaden Research
Center in San Jose, California. The USER lab focuses on creating
complete end-user experiences in the medium of computation - it's more
than just the GUI, but the entire set of moment-by-moment perceptions
and interactions. These experience designs range from input devices
(TrackPoint) to output devices (Digital Jewelry), software
intermediaries (Web-based Intermediaries for augmented web use),
perceptual sensing systems (BlueEyes for attentive environments) and
media analysis tools (CueVideo).
Prior to his engagement at IBM, Dan worked at both Xerox PARC and
Apple's Advanced Technology Group. He founded and managed the User
Experience Research (UER) groups at both places.
