The target article describes two neural models that link the brain's lexical representations with the neural circuitry responsible for speech motor control. These models form an important contribution to the speech and language research literature, which contains very few models that link linguistic entities with speech motor control mechanisms, and even fewer that incorporate both neuroanatomical and computational treatments. As a long-time believer in the importance of neurocomputational

... s for elucidating brain function, I find this work exciting and important. However, both the SFC and HSFC models are at an early stage of development, and certain aspects of the models will likely need to be modified. Because my primary expertise is in speech motor control, I will focus the remainder of this commentary on the motor control components of the more recent of the two models, the HSFC model.
