چکیده
The speech signal enhancement is for obtain clean speech signal from noisy signal environment. For multimodal optimization we better to use natural-inspired algorithms. In this paper we use Firefly algorithmWe compare the firefly algorithm with particle swarm optimization technique (PSO). The proposed algorithm contains three important module techniques. Those are preprocessing module, optimization module and spectral filtering module. The signals are taken from Loizou’s database for evaluating proposed technique. In this paper we calculate the perceptional evolution of speech quality (PESQ) and signal to noise (SNR) of the optimized signalsignal. The results of firefly algorithm and PSO are to be compare then we observe that the proposed technique is better than the existing technique.

In this paper, we propose a novel algorithm to enhance the noisy speech in the framework of dual-channel speech enhancement. The new method is a hybrid optimization algorithm, which employs the combination of the conventional θ-PSO and the shuffled sub-swarms particle optimization (SSPSO) technique. It is known that the θ-PSO algorithm has better optimization performance than standard PSO al...

متن کاملSingle channel speech enhancement by frequency domain constrained optimization and temporal masking
A speech enhancement algorithm is proposed that exploits the masking properties of the human auditory system. The enhancement is formulated as a frequency domain constrained optimization problem. The noise components of the noisy speech are suppressed by a gain function subject to the constraint that both the signal distortion and residual noise should fall below the masking thresholds. Tempora...
