A Microphone Array System for Speech Recognition
In the past year, we have studied the microphone-array placement problem and come up with some optimal placements for a linear microphone array. In so doing we have developed a new method for general nonlinear optimization which we call the Stochastic Region Contraction method. This allowed us to get optimal solutions to our problem -globally optimal -in far less time than simulated annealing w...
متن کاملHigh-speed Noise Cancellation with Microphone Array
We propose the use of a microphone array based on independent component analysis as a method for high-speed elimination of noise in speech input to mobile terminals. The effectiveness of the proposed method is confirmed by evaluation experiments that reproduce an actual mobile environment.

Figure 3: Example of phase correlation between two microphones. The peak of this function indicates the inter-channel delay. index associated with peak value of f(t). This delay estimator is computationally convenient and more robust to noise and reverberation than other approaches based on cross-correlation or adaptive ltering. In ideal conditions, the output of Equation (5) is a delta functio...
متن کاملMicrophone Array for Headset with Spatial Noise Suppressor
This paper presents a hybrid microphone array architecture used for processing the signals from a small microphone array that is used in a headset. The processing chain consists of fixed end-fire beamforming, adaptive spatial noise reduction and stationary noise suppression. The far-field design algorithm used for the fixed beamformer is adapted to the specifics of the headset by compensating f...
