abstract = { In this study we describe a new model of how phonetic knowledge guides
speech production. In the Context Sequence model, target acoustic
patterns are determined based on selection of previously heard or
produced sounds from a memory store. Since signals in the memory
correspond to long stretches of continuous speech, individual speech
sounds always appear in a larger context. A key property of the model
is that the selection of exemplars for production is weighted by
the similarity of the contexts in which they originally occurred
to the current production context. In two simulations based on realistic
amplitude envelope data extracted from a large single-speaker production
corpus, we demonstrate that (1) optimal selection of context-appropriate
segment-level exemplars requires consideration of about 0.5 s of
context material preceding and following exemplars and (2) context-dependent
production at this low level may be responsible for a range of frequency
effects that have previously been assumed to involve word, syllable,
and other higher levels of organization.},
