An auditory modality brain computer interface (BCI) is a novel and interesting paradigm in neurotechnology applications. The paper presents a concept of auditory steady state responses (ASSR) utilization for the novel BCI paradigm. Two EEG feature extraction approaches based on a bandpass filtering and an AR spectrum estimation are tested together with two classification schemes in order to validate the proposed auditory BCI paradigm. The resulting good classification scores of users intentional choices, of attending or not to the presented stimuli, support the hypothesis of the ASSR stimuli validity for a solid BCI paradigm.
听觉模态脑机接口（BCI）是神经技术应用中一种新颖且有趣的范式。本文提出了一种将听觉稳态反应（ASSR）用于新型BCI范式的概念。基于带通滤波和自回归谱估计的两种脑电图特征提取方法与两种分类方案一起进行了测试，以验证所提出的听觉BCI范式。用户对呈现的刺激进行有意选择（即是否关注）时所得到的良好分类分数，支持了ASSR刺激对于可靠的BCI范式具有有效性的假设。
