References on F0 Estimation

An often-cited book on classical methods for pitch detection, particularly for voice, is that by Hess [176]. The harmonic comb method can be considered an approximate maximum-likelihood pitch estimator, and more accurate maximum-likelihood methods have been worked out [107,525,348,349]. More recently, Klapuri has been developing some promising methods for multiple pitch estimation [240,239,238].^5.9
