Examining the Relationship Between Enclosure Ratio of Street and Skyline’s Complexity

open access: yesIconarp International Journal of Architecture and Planning, 2021
Purpose The urban design criteria significantly affect the visual quality of space. Enclosure and Complexity can be defined as two crucial urban design principles that affect the perceptibility and visual quality of space. This study aimed to offer an

HMM-based speech synthesiser using the LF-model of the glottal source [PDF]

open access: yes, 2011
A major factor which causes a deterioration in speech quality in HMM-based speech synthesis is the use of a simple delta pulse signal to generate the excitation of voiced speech.

Lessons from digital puppetry - Updating a design framework for a perceptual user interface [PDF]

open access: yes, 2015
While digital puppeteering is largely used just to augment full body motion capture in digital production, its technology and traditional concepts could inform a more naturalized multi-modal human computer interaction than is currently used with the new ...

JND-Based Perceptual Video Coding for 4:4:4 Screen Content Data in HEVC [PDF]

open access: yes, 2018
The JCT-VC standardized Screen Content Coding (SCC) extension in the HEVC HM RExt + SCM reference codec offers an impressive coding efficiency performance when compared with HM RExt alone; however, it is not significantly perceptually optimized.

Evaluative pressure overcomes perceptual load effects

open access: yesPsychonomic Bulletin & Review, 2014
Perceptual load has been found to be a powerful bottom-up determinant of distractibility, with high perceptual load preventing distraction by any irrelevant information. However, when under evaluative pressure, individuals exert top-down attentional control by giving greater weight to task-relevant features, making them more distractible from task ...

Perceptual evaluation of alaryngeal speech.

open access: yesCollegium antropologicum, 2012
The aim of this study was to compare the self-assessed vocal handicap of laryngectomees treated with three different communication methods: tracheoesophageal speech, esophageal speech and electrolarynx. Forty-eight patients, 40 males and 8 females, who had undergone total laryngectomy for laryngeal carcinoma were enrolled in the study. Depending on the

Comparison of Impulse Response Generation Methods for a Simple Shoebox-Shaped Room

open access: yesAcoustics
Simulated room impulse responses (RIRs) are important tools for studying architectural acoustics. Many methods exist to generate RIRs, each with unique properties that need to be considered when choosing an RIR synthesis technique.

Event-related potential correlates of sound organization: Early sensory and late cognitive effects [PDF]

open access: yes, 2013
We tested whether incoming sounds are processed differently depending on how the preceding sound sequence has been interpreted by the brain. Sequences of a regularly repeating three-tone pattern, the perceived organization of which spontaneously switched
