Doa Estimation of Speech Signal with a Small Number of Microphone Array in Real Acoustical Environment
نویسندگان
چکیده
In this paper, we propose a DOA(Direction of Arrival) estimation of speech signal under reverberant influence. We previously proposed a method of estimating DOA for speech by exploiting the harmonic structure existing in voiced sound [1]. However this method is not always robust to reverberations that usually exist in practical indoor environments. Our new proposal aims to suppress the reverberation effects by applying an idea of the spatial smoothing technique to our conventional method. To prove the efficiency of the method, we show some results of the experiments in two conference rooms.

DOA estimation of speech signal using equilateral-triangular microphone array
In this contribution, we propose a DOA (Direction Of Arrival) estimation method of speech signal whose angular resolution is almost uniform with respect to DOA. Our previous DOA estimation method[1] achieves high precision with only two microphones, however its resolution degrades as the propagating direction apart from the array broadside. In the proposed method, the equilateral-triangular mic...
متن کاملReal-time Blind Source Separation and Doa Estimation Using Small 3-d Microphone Array
We present a prototype system for real-time blind source separation (BSS) and directions of arrival (DOA) estimation. Our system uses a small three-dimensional array with 8 microphones and has the ability to separate signals distributed in threedimensional space. The mixed signals observed by the microphone array are processed by Independent Component Analysis (ICA) in the frequency domain. The...
متن کاملDirection of Arrival Estimation Based on Subband Weighting for Noisy Conditions
In this paper, we present a novel DOA estimation method for human speech using subband weighting. Existing DOA estimation methods still can not perform quite reliably in low SNR condition. To improve the robustness of DOA estimator in noisy environment, we propose a novel DOA estimation approach. Firstly, the speech signal of each channel is passed through a Gammatone filterbank to obtain a set...

One of the important issues in many of array systems such as Radar, Sonar, Mobile, and satellite telecommunications is the estimation of DOA of narrowband received signal. CRB is very important in evaluation of parameter estimation. CRB is the lower bound estimation error variance for any unbiased estimation. In this paper, the array antenna with equal distance arrays is extended in two separat...
متن کاملImplementation of the direction of arrival estimation algorithms by means of GPU-parallel processing in the Kuda environment (Research Article)
Direction-of-arrival (DOA) estimation of audio signals is critical in different areas, including electronic war, sonar, etc. The beamforming methods like Minimum Variance Distortionless Response (MVDR), Delay-and-Sum (DAS), and subspace-based Multiple Signal Classification (MUSIC) are the most known DOA estimation techniques. The mentioned methods have high computational complexity. Hence using...
