Development, perceptual evaluation, and acoustic analysis of amplitude-based F0 control in Electrolarynx speech
… for calculating F0 contours for EL speech, and perceptual experiments and acoustic analyses were conducted to examine the impact of F0 modulation on the quality and prosodic function of the EL speech. The results of perceptual experiments showed that modulating the F0 of EL speech using a linear …

Computational differences between whispered and non-whispered speech
… which is not often studied in speech technology. Perceptual and physiological studies show us that whispered speech is subtly di erent from phonated speech, and is surprisingly able to carry a tremendous amount of information. In this dissertation we con- sider the question: What makes whispering …

Acoustic and perceptual analyses of politeness in Japanese speech
… 'polite' and 'casual')across all the speakers. Perceptual experiments with listeners using a rating scale method confirmed that these acoustic variables, which were manipulated using digital resynthesis, had an impact on politeness perception. It was showed that the duration and fO direction of …

Affect in *Text and Speech
… fundamental parameters of emotional prosody in perceptual experiments with human listeners, indicating both emotion-specific trends and types of variations, and implications at the local word-level. Chapter 6 provides suggestions for continued work in related and novel areas. A concluding …

Perceptual and acoustic impacts of aberrant properties of electrolaryngeal speech
… of EL speech. Using a combination of listening experiments, acoustic analysis and acoustic modeling, this thesis investigated the perceptual and acoustic impacts of several aberrant properties of EL speech, with the overall goal of using the results to direct future EL speech improvement …

Motion quality models for real-time adaptive rendering
… done using an eye tracker through psychophysical experiments involving complex motion on a G-Sync display. Second, I note that the current models of motion quality ignore the effect of displayed content and cannot take advantage of recent shading technologies such as variable-rate shading which …

An Investigation into the Use of Artificial Intelligence Techniques for the Analysis and Control of Instrumental Timbre and Timbral Combinations
… designed to automatically retrieve and identify perceptual qualities of timbre within audio files, using specific musical acoustic features and artificial intelligence algorithms. Different perceptual experiments have been conducted to evaluate the correlation between selected acoustics cues and …

Speech rhythm: the language-specific integration of pitch and duration
… new directions for progress. A series of perceptual experiments investigated the interaction of duration and f0 as perceptual cues to prosody in languages with different prosodic structures – Swiss German, Swiss French, and French (i.e. from France). The first experiment demonstrated that …

The effects of part–of–speech tagging on text–to–speech synthesis for resource–scarce languages
… into the HTS context labels, analytically and perceptually. For the analytical experiments, measures of prosody to quantify the comparisons are explored. It is then also noted whether the results of the perceptual experiments correlate with their analytical counterparts. It is found that, when …

Enhancing voice pitch perception in cochlear implants
… future processing strategies. The results of the perceptual experiments showed, as expected, that ACE performs well in speech recognition tasks, in quiet, providing pleasant and clear sound quality with minimal interference. However, ACE performs poorly in voice pitch perception tasks. Speech …
