Fundamental frequency (F0) control models for singing voices are required to construct singing-voice synthesis systems that can generate natural singing-voices. This paper describes the development of an F0 control model for singing-voices synthesis. F0 fluctuations are revealed as characteristics that need to control the F0 contour of singing-voices by investigating how much they influence sin...

This paper describes a method for estimating the fundamental frequency (F0) of melody and bass lines in monaural audio signals containing sounds of various instruments. Most previous methods premised mixtures of a few sounds and had great difficulty dealing with audio signals sampled from compact discs. Our method does not rely on the unreliable F0’s component and obtains the most predominant F...

In this paper we describe a robust method, called PreFEst, for estimating the fundamental frequency (F0) of melody and bass lines in monaural audio signals containing sounds of various instruments. Most previous F0-estimation methods have difficulty dealing with such complex audio signals because they are designed for mixtures of only a few sounds. Without assuming the number of sound sources, ...

When the voice register transition (VRT) occurs, vocal-folds motion becomes unstable and the voice pitch jumps abruptly. In this article, we examine the relationship between the fundamental frequency f0 and the first-formant frequency F1 in VRT to reveal the influence of the source–filter interaction (SFI) on VRT. Five Japanese male speakers produced rising glissandos with vowels /a/ and /i/. T...

Emotions influence a person’s way of speaking, and it is possible to identify the emotional state of a speaker by merely listening to spoken utterances. The purpose of this study is to distinguish between basic emotions by prosodic features, in particular by characteristics of the fundamental frequency (F0). In addition to the measurement of global features (e.g. average F0 or frequency range) ...

A novel extension to recurrent timing neural networks (RTNNs) is proposed which allows such networks to exploit a joint interaural time difference-fundamental frequency (ITD-F0) auditory cue as opposed to F0 only. This extension involves coupling a second layer of coincidence detectors to a two-dimensional RTNN. The coincidence detectors are tuned to particular ITDs and each feeds excitation to...

The elaboration of rather large spontaneous speech corpora frequently implies the collection of data recorded with poor acoustic quality which may affect its acoustic analysis, and particularly fundamental frequency tracking (F0). Indeed, F0 analysis is particularly sensitive to distortion due to low signal to noise ratio, filtering of low frequencies, encoding in compressed formats (mp3, wma, ...

Pitch is one of the most fundamental percepts in the auditory system and can be extracted using either spectral or temporal information in an acoustic signal. Although pitch perception has been extensively studied in human subjects, it is far less clear how nonhuman primates perceive pitch. We have addressed this question in a series of behavioral studies in which marmosets, a vocal nonhuman pr...

Harmonic complex tones elicit a pitch sensation at their fundamental frequency (F0), even when their spectrum contains no energy at F0, a phenomenon known as " pitch of the missing fundamental ". The strength of this pitch percept depends upon the degree to which individual harmonics are spaced sufficiently apart to be " resolved " by the mechanical frequency analysis in the cochlea. We investi...

This paper describes the relationship between bedrock depth (D) and site fundamental frequency (f0) in Nakdonggang delta region southeastern part of Korean peninsula. We collected borehole logs to confirm thickness sediments estimated f0 at over 200 locations across using horizontal-to-vertical spectral ratio (HVSR) method. developed an map study area by spatially interpolating values Ordinary ...
