The aim of this paper is to design and simulate an AEC in order to enhance the quality of speech disturbed by echo phenomenon. Therefore, in order to design the normalized adaptive AEC, we have used digital signal processing techniques, especially Simulink embedded functions. Effectiveness of the suggested AEC using adaptive normalized algorithm was verified using Matlab/Simulink software. Fina...

For hands-free acoustical human/machine interfaces, e. g. for automatic speech recognition or teleconferencing systems, microphone arrays using robust Generalized Sidelobe Cancellers (GSCs) in conjunction with acoustic echo cancellation (AEC) can be efficiently applied for optimum communication. This contribution devises a new structure for combining AEC and GSC. It reduces the computational co...

Thames Valley area and Lambeth (where 67.9% of practices had Asian or African Caribbean populations constituting 8% of the total population), none were supplementing pregnant women with vitamin D (11). On the basis of the abovementioned evidence, we believe that, at a minimum, the DOH recommendations should be followed, and all pregnant and breastfeeding women should receive 10 g (400 IU) vitam...

We describe a combined nonlinear acoustic echo cancellation and residual echo suppression system. The echo canceler uses parallel Hammerstein branches consisting of fixed nonlinear basis functions and linear adaptive filters. The residual echo suppressor uses an Artificial Neural Network for modeling of the residual echo spectrum from spectral features computed from the far-end signal. We show ...
