Dynamic Phonetic Detail in Lexical Representations
A dynamical model of phonetic detail is presented. The model is compared to an exemplar-based model, which has been shown to offer an account of (presumed) frequency-dependent lenition processes. The dynamical model accounts for the same lenition patterns. However, there is a key difference. In contrast to the exemplar model, the dynamical model provides a handle on the timecourse of assembling...
متن کاملPhonetic Set Indexing for Fast Lexical Access
A novel nonsequential indexing mechanism (termed phonetic set indexing) has been evaluated for the purpose of fast word pre-selection. Our approach to handling the lexical access problem stems from the primary observation that the set of phones which are present in the transcription of a word is sparsely distributed across the vocabulary, and is thus suitable as an indexing key for retrieving a...
متن کاملModelling Context Dependency in Acoustic-Phonetic and Lexical Representations
In 1989, our group first reported on the development of SUMMIT, a segment-based speaker-independent continuous-speech recognition system [13] . The initial version of SUMMIT made use of fairly simple context-independent models for the lexical labels. Recently, we have begun to incorporate more complex models of lexical labels that take into account a variety of contextual factors. These changes...
متن کاملPhonetic Characterisation and Lexical Access in Non-segmental Speech Recognition
An isolated-word speech recognition system, built without the use of linear segments for acoustic modelling or lexical access, is justified, described and demonstrated. The system comprises phonetic feature analysis operating on four independent tiers, parallel phonotactic parsing, and lexical access based on a neural-network inspired lexicon structure. Performance is however still inferior to ...
متن کاملLexical Access with a Statistically-Derived Phonetic Network
A probabilistic approach to lexieal access from a recognized phone sequence is presented. Lexical access is seen as finding the word sequence that maximizes the lexical likelihood of a sequence of phones and durations as recognized by a phone recognizer. This is theoretically correct for minimum error rate recognition within the model presented and is intuitively pleasing since it means that th...
