A theoretical justification has been provided for coincidence of wavelet maxima at a particular scale pair in an event-based pitch detection method. The scale pair to be selected for true pitch estimation in case of multiple scale pairs giving coincidence of wavelet maxima is also indicated, based on this theory. Examples, involving both male and female voice, are provided that demonstrate validity of the theory presented.
