The English term "speak" is usually associated with the notion of speech as central to language. To deconstruct this phonocentric notion, the term "speak" can be applicable to vocal-auditory modality and visual-spatial modality, for both are articulated in the verbal form (that is, the opposite of written form).
Meaning: To say something in order to convey information, an opinion, or a feeling in vocal-aural modality or spoken language.
