人机界面(HMI)设计提供了改善患者群体生活质量以及增强正常用户功能的可能性。尽管有实际的好处，但利用听觉反馈进行人机界面控制仍然没有得到充分利用，部分原因是观察到的有效性方面的局限性。这项研究的目的是确定类别言语知觉在多大程度上可以用来改善听觉HMI。使用表面肌电图仪，24名说美式英语的健康人士参加了4次会议，学习如何使用听觉反馈(通过元音合成提供)来控制人机界面。受试者在第1-3节中对3个目标进行了训练，在第4节中对3个新的目标进行了测试。一个由8名参与者组成的“带有文本线索的既定类别”组使用听觉和文本目标线索对对应于标准美式英语元音的听觉目标进行了训练和测试。一个由8名参与者组成的“没有文本线索的已建立类别”组在相同的目标上进行了训练和测试，只使用目标元音身份的听觉线索。一个由8名参与者组成的“新类别”小组接受了培训和测试，测试目标对应于不属于美国英语的元音发音。对用户绩效的分析表明，会话和组(已建立的类别组和新的类别组)的影响显著，会话和组之间的交互有趋势。结果表明，听觉反馈可以有效地用于HMI操作，当与具有明确提示的已建立的范畴(母语元音)目标配对时。
Human-machine interface (HMI) designs offer the possibility of improving quality of life for patient populations as well as augmenting normal user function. Despite pragmatic benefits, utilizing auditory feedback for HMI control remains underutilized, in part due to observed limitations in effectiveness. The goal of this study was to determine the extent to which categorical speech perception could be used to improve an auditory HMI. Using surface electromyography, 24 healthy speakers of American English participated in 4 sessions to learn to control an HMI using auditory feedback (provided via vowel synthesis). Participants trained on 3 targets in sessions 1–3 and were tested on 3 novel targets in session 4. An “established categories with text cues” group of eight participants were trained and tested on auditory targets corresponding to standard American English vowels using auditory and text target cues. An “established categories without text cues” group of eight participants were trained and tested on the same targets using only auditory cuing of target vowel identity. A “new categories” group of eight participants were trained and tested on targets that corresponded to vowel-like sounds not part of American English. Analyses of user performance revealed significant effects of session and group (established categories groups and the new categories group), and a trend for an interaction between session and group. Results suggest that auditory feedback can be effectively used for HMI operation when paired with established categorical (native vowel) targets with an unambiguous cue.
