the features of Scottish and Irish English, which we
are currently synthesising, and describe how these are

abstract = {We describe a speech recogniser which uses a speech
production-motivated phonetic-feature description of
speech. We argue that this is a natural way to describe
the speech signal and offers an efficient intermediate
parameterisation for use in speech recognition. We also
propose to model this description at the syllable
rather than phone level. The ultimate goal of this work
is to generate syllable models whose parameters
explicitly describe the trajectories of the phonetic
features of the syllable. We hope to move away from
Hidden Markov Models (HMMs) of context-dependent phone
units. As a step towards this, we present a preliminary
system which consists of two parts: recognition of the
phonetic features from the speech signal using a neural
network; and decoding of the feature-based description
into phonemes using HMMs.},

accent-independent lexicon for use in synthesising
speech in English. Lexica which use phonemic
transcriptions are only suitable for one accent, and
developing a lexicon for a new accent is a long and
laborious process. Potential solutions to this problem
include the use of conversion rules to generate lexica
of regional pronunciations from standard accents and
encoding of regional variation by means of keywords.
The latter proposal forms the basis of the current
work. However, even if we use a keyword system for
lexical transcription there are a number of remaining
theoretical and methodological problems if we are to
synthesise and recognise accents to a high degree of
accuracy; these problems are discussed in the following
paper.},
