The auditory pathways are categorized into the dorsal and ventral pathways. The ventral pathway’s function is to decode spectrally complex sounds, for example the meaning of speech sound for people or sounds of animal communication.
Less information is known about the dorsal auditory pathway, but it has important role in the integration of auditory and somatosensory information to regulate speech production. This is known as “audition for action.”
Thus, the blank can be filled with “audition for action.”
