研究者们将Forbes频率作为与日本口音相关的一种可能的声学因素。由本研究的第一作者进行的感知研究使用合成语音刺激，其中每个频谱（F0）的谐波结构从以正常方式产生的语音中去除，并由白色噪声代替。以这种方式产生的刺激确保了从正常语音改变的唯一属性将是F0的存在或不存在。结果发现，日本听众可靠地识别出最小的单词对，只有口音不同，这表明F0不是唯一的声学线索，日本口音。由于先前的研究报告低声讲话的扬声器和共振峰频率之间的音高高度预期的正相关性，共振峰频率被测量为一个可能的相关口音。然而，分析没有发现在原始正常语音中观察到的F0运动与在合成语音中测量到的共振峰频率之间存在任何相关性。
Formant frequencies were examined as a possible acoustic correlate to Japanese accent. A perception study conducted by the first author of the present study used synthetic speech stimuli in which the harmonic structure of each spectrum (F0) was removed from speech produced in a normal manner and replaced by white noise. The stimuli created this way ensured that the only property altered from the normal speech would be the presence or absence of the F0. The result found that Japanese listeners reliably identified minimal pairs of words that differed only by accent, indicating that F0 is not the only acoustic cue to Japanese accent. Since previous studies on whispered speech report a positive correlation between the pitch height intended by speakers and formant frequencies, formant frequencies were measured as a possible correlate to accent. However, the analysis did not find any correlation between the F0 movements observed in the original normal speech and the formant frequencies measured in the synthetic...
