François YVON
Ph.D. Student
Biography
Born 1964 in Poitiers, France, François YVON graduated from the Ecole
Polytechnique in 1987, and from the Ecole Nationale de Statistique et
d'Administration Economique (ENSAE) in 1989. During the same period,
he worked as Research Associate in a Social Science Laboratory, where
his main research topic was the automatic treatment of open questions
in surveys using lexicometric methods. After three years as Project
Manager in the Pharmaceutical Industry, he joined TELECOM Paris in 1992
to start a Ph.D in computationnal Linguistics under the direction of
Pr. A. BONNET. Since then, his research activity has been devoted to
the question of grapheme to phoneme transcription of proper names
(people first and last names, place names and acronyms) for speech synthesis.
This includes both a careful study of specific morphological, phonological
and syntactical properties of these ``weird'' linguistic componants, and a
study of self-learning techniques that could help to carry out phonemic
transcription.
He is is also responsible for building a 1 million entries lexicon
(including a phonemic transcription) of French proper names, within the
LRE project ONOMASTICA.

Grapheme-to-Phoneme Conversion Systems for Proper Names
Pronuncing proper names (patronyms, toponyms or acronyms) is
commonly known to be a difficult task for many speech synthesis systems.
These difficulties have numerous causes, such as exotic etymologies or the
vagueness of the concept of "a good pronunciation for a name", etc.
The goal of this PhD work is to explore and/or implement systems
(either rule or analogy based) specifically devoted to the grapheme to
phoneme conversion of these weird linguistic entities; systems which
would be of great interest for the development of name intensive real
word text-to-speech applications.
