与目光无关的脑机接口（BCI）是瘫痪患者的一种可能的沟通渠道。我们调查了是否有可能使用听觉刺激来创建日本平假名音节表的BCI，其中有46个平假名字符。此外，我们调查了训练是否对准确性有影响，尽管涉及大量不同的刺激。健全的参与者（N = 6）被要求选择25个音节（50个可能的选择）使用两个步骤的程序：首先是辅音（10个选择），然后是元音（5个选择）。这在3个不同的日子重复。此外，一名患有脊髓损伤（SCI）的人参加了实验。六个健康的参与者中有四个达到了70%以上的平假名音节准确度，信息传输速率从第一次会议的1.7位/分钟增加到第三次会议的3.2位/分钟。SCI参与者的准确性从12%（0.2位/分钟）增加到56%（2位/分钟）。使用听觉刺激从10 × 5矩阵中进行可靠的选择是可能的，并且通过训练提高了性能。我们能够证明听觉P300脑机接口可以用于多达50个符号的通信。这使得听觉P300脑机接口技术能够用于各种应用。
Gaze-independent brain-computer interfaces (BCIs) are a possible communication channel for persons with paralysis. We investigated if it is possible to use auditory stimuli to create a BCI for the Japanese Hiragana syllabary, which has 46 Hiragana characters. Additionally, we investigated if training has an effect on accuracy despite the high amount of different stimuli involved. Able-bodied participants (N = 6) were asked to select 25 syllables (out of fifty possible choices) using a two step procedure: First the consonant (ten choices) and then the vowel (five choices). This was repeated on 3 separate days. Additionally, a person with spinal cord injury (SCI) participated in the experiment. Four out of six healthy participants reached Hiragana syllable accuracies above 70% and the information transfer rate increased from 1.7 bits/min in the first session to 3.2 bits/min in the third session. The accuracy of the participant with SCI increased from 12% (0.2 bits/min) to 56% (2 bits/min) in session three. Reliable selections from a 10 × 5 matrix using auditory stimuli were possible and performance is increased by training. We were able to show that auditory P300 BCIs can be used for communication with up to fifty symbols. This enables the use of the technology of auditory P300 BCIs with a variety of applications.
