Methods for estimating articulatory data from acoustic measurements are reviewed. First, relations between the vocal-tract area function and formant or impedance data are pointed out. Then the possibility of determining a (discretized) area function from the speech signal itself is considered. Finally, we look at the estimation of certain articulatory parameters rather than the area function. By using a regression method, such parameters can even be estimated independently of any vocal-tract model. Results for real-speech data are given.
回顾了从声学测量估计发音数据的方法。首先，指出了声道面积函数与共振峰或阻抗数据之间的关系。然后考虑了从语音信号本身确定（离散化的）面积函数的可能性。最后，我们着眼于某些发音参数的估计而非面积函数。通过使用回归方法，甚至可以独立于任何声道模型来估计此类参数。给出了真实语音数据的结果。
