The definition of auditory imagery is analogous to definitions used in other modalities of imagery (such as visual, auditory and olfactory imagery) in that it is, according to Intons-Peterson (1992), "the introspective persistence of an auditory experience, including one constructed from components drawn from long-term memory, in the absence of direct sensory instigation of that experience.". Auditory imagery is often but not necessarily influenced by subvocalization, and has ties to the rehearsal process of working memory. The conception of working memory relies on a relationship between the "inner ear" and the "inner voice" (subvocalization), and this memory system is posited to be at the basis of auditory imagery. Subvocalization and the phonological store work in partnership in many auditory imagery tasks.
