This paper proposes that styles of singing in which pitch is fixed, categorical and independent of loudness are a by-product of the development of artificial musical instruments capable of this loudness-pitch independence. The argument is based on the physical and consequent acoustic properties of the voice. The voice is well suited to producing a wide range of phonemes (comparable with a wide ...

Timbre can be defined as feature of an auditory stimulus that allows us to distinguish the sounds which have the same pitch and loudness. In this paper, we explore timbre based perceptual feature for singer identification. We start with a vocal detection process to extract the vocal segments from the sound. The cepstral coefficients, which reflect timbre characteristics, are then computed from ...

Mouse control has become a crucial aspect of many modern day computer interactions. This poses a challenge for individuals with motor impairments or those whose use of hands are restricted due to situational constraints. We present a system called the Vocal Joystick which allows the user to continuously control the mouse cursor by varying vocal parameters such as vowel quality, loudness and pit...

Vocal fry is a voice quality that occurs in healthy voice, but it can also be sign of disorder. In this study, we investigated the relationship between parameters production, dedicated psychoacoustic feature, and perceptual aspects vocal fry. Two experiments were carried out to determine whether fundamental frequency, open quotient, glottal area pulse skewness affect perception synthetic vowels...

The ability to modulate vocal sounds and generate speech is one of the features which set humans apart from other living beings. The human voice can be characterized by several attributes such as pitch, timbre, loudness, and vocal tone. It has often been observed that humans express their emotions by varying different vocal attributes during speech generation. Hence, deduction of human emotions...

We will demonstrate a novel voice-based human-computer interface we call the Vocal Joystick (VJ), designed to enable individuals with motor impairments to use vocal parameters for both discrete and continuous control tasks. Since discrete spoken commands are not ideally suited to such tasks, our methodology exploits a large set of continuous acoustic-phonetic parameters like pitch, loudness, vo...

This study examines measures of the glottal airflow waveform, the electroglottographic signal (EGG), amplitude differences between peaks in the acoustic spectrum, and observations of the spectral energy content of the third formant (F3), in terms of how they relate to one another. Twenty females with normal voices served as subjects. Both group and individual data were studied. Measurements wer...

Although many quantitative parameters have been devised to describe abnormalities in vocal fold vibration, little is known about the priority of these parameters. We conducted a prospective study using high-speed digital imaging elucidate disease-specific key (KPs) characterize vibrations individual voice disorders. From 304 patients with various disorders and 46 normal speakers, sustained phon...

parkinsonian speech is characterized by abnormally low voice intensity, with vocal decay, poor voice quality, reduced prosodic pitch and loudness inflection, imprecise vowels and consonants, dysrhythmia and short rushes of speech, mumbling, and reduced speech intelligibility. recently, there have been new acoustic analysis methods to capture different aspects of these speech abnormalities. in t...
