The articulatory motor cortex plays a large role in speech perception. Disrupting this cortex using repetitive Transcranial Magnetic Stimulation (TMS) has shown significant decrease in performance on demanding speech perception tasks (Möttönen, Rogers, & Watkins, 2014). When hearing speech in difficult listening conditions, our auditory system recruits the articulatory motor cortex to assist with speech perception. Further TMS studies have been used to demonstrate this effect, finding that the excitability of the lip motor region increases distorted speech conditions compared to clear speech conditions (Nuttall et al., 2016). This suggests that in difficult speech conditions, the articulatory motor system interacted with the auditory speech systems more than in clear speech.

关节运动皮层在语音感知中起着重要作用。使用重复的经颅磁刺激（TMS）破坏这种皮质的表明，表达言语感知任务的性能显着下降（Möttönen，Rogers和Watkins，2014年）。当在艰难的听力条件下聆听语音时，我们的听觉系统会招募关节运动皮层以帮助语音感知。进一步的TMS研究已被用来证明这种影响，发现与清晰的语音条件相比，唇部运动区域的兴奋会增加语音条件（Nuttall等，2016）。这表明，在艰难的语音条件下，关节电机系统与听觉语音系统相互作用比清晰的语音互动。
