A Knowledge-Based System for Voiceless Plosive Reooding

A local learning system for acoustic phonetic decoding of French voiceless plosives is
described. A rule-base is worked out from both a labelled acoustic phonetic data-base and a
statistical one.
Locally, rules using the concept of fuzziness are arrived at through:
- yielding automatically (based on statistics) restriction boundaries for each /iPFi
membership function that is associated to a (parameter P, function F) pair,
- working out a synthetic, arborescent AND/OR rule...
Globally, an automaton is defined for each phoneme whose states refer to a part of the
rule-base.
Operating within a decoding procedure, this system allows to define rules and to
test the various parameter/function pairing combinations.
