A Neural Model Of Speech Production And Its Application To Studies Of The Role Of Auditory Feedback In Speech
Frank H. Guenther, Joseph S Perkeu · 2004
Abstract The overall objective of our research is to model the brain activity and the motor, biomechanical and sensory processes involved in speech production. Our approach is to use a combination of computational models and to develop and test them with brain imaging, psychophysical, physiological, anatomical and acoustic data. In particular, we have developed a neural network model of speech motor skill acquisition and speech production, called the DIVA model, that explains a wide range of data on contextual variability, motor equivalence, coarticulation and speaking rate effects (Guenther 1994, 1995a, b; Guenther and Micci Barreca 1997; Guenther et al. 1998; Perkell et al. 2000). This model is schematized in Fig. 2.1. In this chapter we provide a description of the model and its neural correlates, and we present results of studies on an important aspect of the model: the role of auditory feedback in the planning of speech movements.
