众所周知，自声产生（在发声过程中听到自己的声音）和外声产生（录音后听到自己的声音）的音色是不同的。然而，这两种产品之间的差异尚未得到定量评估。这自然是因为没有客观的方法来评估自声产生中的声音音色。本研究的目的是提出一种名为延迟反馈法的方法，该方法可以客观地检测男性受试者在口语模式下发出五个日语元音时，自声产生中的语音音色作为频率的函数，并与外音产生中的音色进行定量比较。进行该实验是为了通过扬声器尽可能准确地模拟声音，其音色和响度与发声期间所感知的一致。结果发现，对于所有的元音，与记录后的再现声音相比，人声在低频区被感知为相对较大（在100 Hz时约5 dB），而在高频区被感知为相对较软（在4 kHz时约-5 dB）。这可能是由发声期间的骨传导元件引起的。事实上，所获得的调查结果也与日常生活中的经验相吻合。
It is well known that voice timbre in autophonic production (hearing one's own voice during phonation) is different from that in extraphonic production (hearing one's voice after recording). The differences between the two productions, however, have not been evaluated quantitatively. This results naturally from the fact that there is no objective way to evaluate the voice timbre in autophonic production. The purpose of the present study was to show a method, named the delayed feedback method created by the author, in which voice timbre in autophonic production can be examined objectively, as a function of frequency, and then to evaluate the timbre in comparison with that in extraphonic production quantitatively, when male subjects phonated five Japanese vowels in the spoken mode. The experiment was conducted so as to simulate the sound through a loudspeaker as accurately as possible in its timbre and loudness to that perceived during phonation. It was found that, for all the vowels, the vocal sound was perceived relatively louder in the low frequency region (about 5 dB at 100 Hz) and softer in the high frequency region (about -5 dB at 4 kHz) than the reproduced sound after recording. This may result from the bone conduction elements during phonation. The findings obtained do also, in fact, coincide with experiences in everyday life.
