Auditory feedback in the headphones of talkers was manipulated in the F1 dimension using a real-time vowel formant filtering system. Minimum formant shifts required to elicit a response and the amount of compensation were measured for vowels across the English vowel space. The largest response in production of F1 was observed for the vowel /ε/ and smaller or non-significant changes were found for point vowels. In general, changes in production were of a compensatory nature that reduced the error in the auditory feedback.
使用实时元音共振峰滤波系统在F1维度上对说话者耳机中的听觉反馈进行了操控。针对英语元音空间中的各个元音，测量了引发反应所需的最小共振峰偏移以及补偿量。在元音/ε/的F1产生过程中观察到最大的反应，而对于单元音则发现变化较小或无显著变化。总体而言，产生的变化具有补偿性质，减少了听觉反馈中的误差。
