音色是区分相同音高、响度和持续时间的声音的属性。它有助于我们感知和区分语音中的不同元音和辅音，音乐中的乐器和环境声音。在这里，我们开始回顾人类的音色感知和频谱和时间的声学特征，引起语音，音乐和环境声音的音色。我们还考虑了动物对音色的感知，包括人类元音和非人类发声。然后，我们探讨了音色的神经表征，首先在外周听觉系统，后来在听觉皮层的水平。我们研究了涉及音色感知的神经网络和可能在听觉皮层中执行的计算，以使听众能够提取有关音色的信息。我们考虑是否在听觉皮层的单个神经元能够代表光谱音色独立于其他感知属性的变化和机制，可能塑造神经灵敏度的音色。最后，我们总结了一些关于神经机制在行为中的作用仍然存在的问题，并考虑了未来研究的一些潜在的富有成效的途径。
Timbre is the attribute that distinguishes sounds of equal pitch, loudness and duration. It contributes to our perception and discrimination of different vowels and consonants in speech, instruments in music and environmental sounds. Here we begin by reviewing human timbre perception and the spectral and temporal acoustic features that give rise to timbre in speech, musical and environmental sounds. We also consider the perception of timbre by animals, both in the case of human vowels and non-human vocalizations. We then explore the neural representation of timbre, first within the peripheral auditory system and later at the level of the auditory cortex. We examine the neural networks that are implicated in timbre perception and the computations that may be performed in auditory cortex to enable listeners to extract information about timbre. We consider whether single neurons in auditory cortex are capable of representing spectral timbre independently of changes in other perceptual attributes and the mechanisms that may shape neural sensitivity to timbre. Finally, we conclude by outlining some of the questions that remain about the role of neural mechanisms in behavior and consider some potentially fruitful avenues for future research.
