a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
15 صفحه اولReconstruction filter design for bone-conducted speech
Bone-conducted speech is of low intelligibility, but its quality is not affected by noise. In this paper, we take into account such propertes of bone-conducted speech, and address a digital filter to reconstruct the quality of the bone-conducted speech signal obtained from a speaker. The reconstruction filter design method is derived based on a model assumption of pronunciation. Experimental re...
متن کاملModel-based speech enhancement using a bone-conducted signal.
Codebook-based single-microphone noise suppressors, which exploit prior knowledge about speech and noise statistics, provide better performance in nonstationary noise. However, as the enhancement involves a joint optimization over speech and noise codebooks, this results in high computational complexity. A codebook-based method is proposed that uses a reference signal observed by a bone-conduct...
متن کاملPitch estimation in noisy speech based on temporal accumulation of spectrum peaks
In this paper, we present a study on robust pitch estimation by integrating spectral and temporal information in speech. Spectrum harmonics are important representations of the speech fundamental frequency. Harmonic-related spectral peaks of speech evolve much more slowly than the spectral peaks of noise. This motivates the proposition of temporally accumulated peak spectrum (TAPS), which is co...
متن کاملHigh Pitch Delay Resolution Technique for Tonal Language Speech Coding Based on Multi-Pulse Based Code Excited Linear Prediction Algorithm
Problem statement: In spontaneous speech communication, speech coding is an important process that should be taken into account, since the quality of coded speech depends on the efficiency of the speech coding algorithm. As for tonal language which tone plays important role not only on the naturalness and also the intelligibility of the speech, tone must be treated appropriately. Approach: This...
