我们提出了一种新的设计，人工机器人耳朵和声音方向估计方法，仅使用测量的两个输出信号。头相关传递函数和耳间传递函数的频谱特征在整个语音频带上是不同的。因此，这些特征提供有效的声音提示以使用测量的两个输出信号来估计声音方向。麦克风位置的双边不对称性可以提高估计性能，即使在中间平面，耳间差异消失。声音方向的估计，从两耳间的时间差和两耳间传递函数的对数幅度之间的相关性。在真实的环境中验证了所设计的人工耳及其估计方法的可行性和估计性能。在实验中，我们证实，机器人与建议的人工耳可以找到用户的方向，从两个输出信号只有合理的精度。
We propose a novel design of artificial robot ear and sound direction estimation method using the measured two output signals only. The spectral features in head-related transfer functions and in interaural transfer functions are distinctive across voice frequency band. Thus, these features provide effective sound cues to estimate sound direction using the measured two output signals. Bilateral asymmetry of microphone positions can enhance the estimation performance even in the median plane where interaural differences are vanished. Sound direction is estimated from interaural time difference and correlation between the log magnitudes of interaural transfer functions. The feasibility and the estimation performance of the designed artificial ear and the estimation method are verified in a real environment. In the experiment, we confirm that robots with the proposed artificial ear can find the direction of user from two output signals only with reasonable accuracy.
