Human speech allows to convey information via different execution forms. Thus, on the behavioral level, speech content is independent from production and execution forms. However, it remains unclear whether such a content dimension can be found on the neural level and whether it is possible to dissociate it from the motor dimension. To address this, we recorded magnetoencephalography (MEG) in human subjects that performed two rule-based vocalization tasks. In the first experiment, content (one of two vowels) and production (overt or covert) were instructed separately and in random order. Apply
