Nettet10. apr. 2024 · Physiological interpretation and model order. Linear prediction has a surprising connection with physical modelling of speech production. Namely, a linear predictive model is equivalent with a tube-model of the vocal tract (see figure on the right). A useful consequence is that from the acoustic properties of such a tube-model, we can … NettetMatlab's LPC documentation refers to this as "the prediction filter polynomial", and it's very useful for e.g. finding the formants of a signal (which are simply the zeroes of this polynomial). But I don't understand the connection between these two uses. Why is it useful to turn the linear prediction coefficients into a polynomial like this?
