  • Boardman, Ian; Grossberg, Stephen; Myers, Christopher; Cohen, Michael (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-06)
    How does the brain extract invariant properties of variable-rate speech? A neural model, called PHONET, is developed to explain aspects of this process and, along the way, data about perceptual context effects. For example, ...
  • Boardman, Ian; Grossberg, Stephen; Cohen, Michael (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-12)
    The perception of CV syllables exhibits a trading relationship between voice onset time (VOT) of a consonant and duration of a vowel. Percepts of [ba] and [wa] can, for example, depend on the durations of the consonant and ...
  • Grossberg, Stephen; Boardman, Ian; Cohen, Michael (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-12)
    What is the neural representation of a speech code as it evolves in real time? A neural model of thiss process, called the ARTPHONE model, is developed to quantitatively simulate data concerning segregation and integration ...
  • Boardman, Ian; Cohen, Michael; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)
    Speech can be understood at widely varying production rates. A working memory is described for short-term storage of temporal lists of input items. The working memory is a cooperative-competitive neural network that ...
