为了研究言语协调，我们经常平均运动和其他生理信号。平均数被认为比个别记录更能代表生产的基本模式。在本说明中，我们概述了不同的平均方法，并提出了一种新的非线性归一化技术，提供更好的信息比合奏平均，线性归一化，或特征对齐方法。我们建议，这种技术提供了一个清晰的模式形状的估计，同时保留随时间变化的信息。
In order to study speech coordination we frequently average kinematic and other physiological signals. The averages are assumed to be more representative of the underlying patterns of production than individual records. In this note we outline different approaches to averaging and present a new nonlinear normalization technique that offers better information than ensemble averaging, linear normalization, or feature alignment methods. We suggest that this technique provides a clear estimation of pattern shape while preserving information on the variation over time.
