This study investigated whether lower vagal function in preterm infants is associated with increased fundamental frequency (F0 ; frequency of vocal fold vibration) of their spontaneous cries. We assessed respiratory sinus arrhythmia (RSA) during quiet sleep as a measure of vagal function, and its relationship with the F0 of spontaneous cries in healthy preterm and term infants at term-equivalen...

In Parkinson's Disease (PD), qualitative speech changes such as decreased variation in pitch and loudness are common, but quantitative vocal changes are not well documented. The variability of fundamental frequency (F0) in 32 individuals (23 male) with PD both ON and OFF levodopa medication was compared with 32 age-matched healthy controls (23 male). Participants read a single paragraph and est...

We submit a method for the MIREX 2008 task “Audio Melody Extraction”. The method first transcribes input audio file into MIDI notes and then estimates fundamental frequency (F0) trajectory for each note. The melody transcription method uses a frame-wise pitch salience estimator to measure the strength of different fundamental frequencies. HMMs are used to model melody notes, other instrument no...

Estimating fundamental frequencies in polyphonic music remains a notoriously difficult task in Music Information Retrieval. While other tasks, such as beat tracking and chord recognition have seen improvement with the application of deep learning models, little work has been done to apply deep learning methods to fundamental frequency related tasks including multi-f0 and melody tracking, primar...

In this paper, we propose a model to generate fundamental frequency (F0) contours using neural networks. A learning procedure is proposed as an alternative to synthesis-by-rules. The generation of correct fundamental frequency contour is one of the important issues in the naturalness of automatic text-to-speech conversion systems. The proposed approach is based on a standard feed-forward multi-...

Background: Repeated efforts by researchers to impose voice changes by laryngeal surface electrical stimulation (SES) have come to no avail. This present pre-experimental study employed a novel method for SES application so as to evoke the motor potential of the internal superior laryngeal nerve (ISLN) and create voice changes.Methods: Thirty-two normal individuals (22 females and 10 males) par...

A new method for robust estimation of fundamental frequency (F0) from speech signal is proposed in this paper. The method exploits the high SNR regions of speech in time and frequency domains in the outputs of single frequency filtering (SFF) of speech signal. The high resolution in the frequency domain brings out the harmonic characteristics of speech clearly. The harmonic spacing in the high ...

This study compared voice range profiles (VRPs) of modal and falsetto register in 53 dysphonic non-dysphonic adult women with gliding vowel /a/’. The results shows that maximum fundamental frequency (F0MAX), intensity (IMAX), F0 (F0RANGE), (IRANGE) are lower the group than group. F0MAX F0RANGE significantly higher both groups. I<...

This paper describes a computer program for synthesizing fundamental frequency (F0} contours for English, and sketches the theory which underlies it. The F0 contour is described as a series of targets within an envelope specifying F0 range; the F0 contour between targets is computed by transition rules. The use of nonmonotonic transitions permits a sparser specification of the contour than has ...
