Métodos de Mitigação de Efeitos Reverberantes e Ruidosos com Ganho de Inteligibilidade e Qualidade

This work presents an analysis of methods to improve intelligibility and quality of speech signals under noisy reverberant scenarios. Four methods (SSFV, APES_HARM, SCOE and GTF_F0) are considered in the evaluation for three different reverberation rooms and four noises with different degrees of nonstationarity. Two objective intelligibility measures (ESTOI and ASII_ST) and two quality measures (PEAQ and PESQ) are applied for objective assessment. Results show that the GTF_F0 solution leads to the highest improvement in terms of intelligibility and quality.
