A study on measurement of brain activities with speech production and perception under transferred auditory feedback conditions

本研究以“听觉反馈”作为言语产生和知觉之间亲和力的一个例子，并通过fMRI的脑活动测量，揭示了当传递听觉反馈时，大脑的哪些部分被激活。为了测量大脑活动，我们开发了能够与fMRI一起使用的传输听觉反馈的呈现和采集设备，然后使用这些设备通过fMRI测量大脑活动。此外，我们通过使用EMA测量舌头运动来检验语音产生和感知之间的关系。

This study focuses on "auditory feedback" as an example of affinity between speech production and perception, and reveals which parts of the brain are activated with which turn when transferred auditory feedback is presented, through brain activity measurements with fMRI. To measure the brain activities, we develop presentation and collection devices for the transferred auditory feedback that is able to be used with fMRI, and then we measure the brain activities by fMRI using these devices. Moreover, we examine relations between speech production and perception by tongue movement measurements using EMA.
