Introduction: Rhinosinus polyposis is associated with voice quality reduction. There has been little evidence about the efficacy of rhinosinus polyps surgery on patients' voice quality so far. The aim of the present study was to evaluate the nasality and acoustic voice changes after rhinosinus polyposis surgery.   Materials and Methods: The population in this study compo...

Voice control has long been considered as a natural mechanism to assist powered wheelchair users. However, one implementation difficulty is that a voice input system may fail to recognise a user’s voice. Indeed, speech activated interface between human and autonomous/semi-autonomous systems requires accurate detection and recognition. In this area pitch and end-point detection is of vital impor...

Voice assistants like Siri enable us to control IoT devices conveniently with voice commands, however, they also provide new attack opportunities for adversaries. Previous papers attack voice assistants with obfuscated voice commands by leveraging the gap between speech recognition system and human voice perception. The limitation is that these obfuscated commands are audible and thus conspicuo...

he voice recognition is the method that calculates an optimal match between two given sequences with certain restrictions is called Dynamic time wrapping. The sequences are "warped" non-linearly in the time dimension to determine a measure of their similarity independent of certain non-linear variations in the time dimension. This sequence alignment method is often used in time series classific...

Mobile device based personalized equalizer for improving the hearing capability of human voices in particular for elderly persons are proposed. Through experiments, it is found that the proposed equalizer does work well for improving hearing capability by 2 to 55 % of voice Recognition success ratio. According to the investigation of the frequency component analysis and formant detections, most...

Sketches are a commonly used tool in the early stages of design. Our previous system, ASSIST(Alvarado, 2000), lets users sketch in a natural fashion and recognizes mechanical systems. ASSIST also interfaces with a simulation tool to show users their sketch in action. ASSISTANCE(Oltmans, 2001) builds on ASSIST by allowing the user to use additional sketching and voice input to describe the behav...

In this paper, we proposed an all optical 4-to-2 encoder that has 4 input and 3 output ports. This device generates a 2 bit binary code based on which input port is active. We used nonlinear photonic crystal ring resonators along with optical power splitter for realizing the proposed encoder. In this device the switching rate and area are obtained about 333 GHz and 612µm2 respectively.
