音高传达语音、音乐和其他自然声音中的关键信息，并且传统上被定义为声音的基频（F0）的感知相关。虽然间距被广泛认为是subserved由一个单一的F0估计过程中，现实世界的间距任务变化很大，提高潜在的机械多样性的可能性。为了探索音高机制，我们使用传统的和声和频率缺乏共同F0的非和声进行了一系列与音高相关的音乐和语音任务。一些与音高相关的能力--那些依赖于音程或语音识别的能力--被不和谐严重削弱，这表明他们依赖于F0。然而，其他任务，包括那些依赖于语音和音乐中的音高轮廓的任务，不受不和谐的影响，这表明一种跟踪频谱而不是F0的机制。结果表明，音高感知是由几个不同的机制，其中只有一些符合传统的音高概念。
Pitch conveys critical information in speech, music, and other natural sounds, and is conventionally defined as the perceptual correlate of a sound's fundamental frequency (F0). Although pitch is widely assumed to be subserved by a single F0 estimation process, real-world pitch tasks vary enormously, raising the possibility of underlying mechanistic diversity. To probe pitch mechanisms we conducted a battery of pitch-related music and speech tasks using conventional harmonic sounds and inharmonic sounds whose frequencies lack a common F0. Some pitch-related abilities – those relying on musical interval or voice recognition – were strongly impaired by inharmonicity, suggesting a reliance on F0. However, other tasks, including those dependent on pitch contours in speech and music, were unaffected by inharmonicity, suggesting a mechanism that tracks the frequency spectrum rather than the F0. The results suggest that pitch perception is mediated by several different mechanisms, only some of which conform to traditional notions of pitch.
