References on F0 Estimation

An often-cited book on classical methods for pitch detection, particularly for voice, is that by Hess [191]. The harmonic comb method can be considered an approximate maximum-likelihood pitch estimator, and more accurate maximum-likelihood methods have been worked out [113,559,375,376]. More recently, Klapuri has been developing some promising methods for multiple pitch estimation [261,260,259].^5.14
