Word intelligibility estimation of noise-reduced speech

چکیده
It is indispensable to establish an objective test methodology for noise-reduced speech. This paper proposes a new methodology which estimates word intelligibility of the noise-reduced speech from PESQ MOS (subjective MOS estimated by the PESQ). To evaluate the effectiveness of the proposed methodology, a word intelligibility test of the noise-reduced speech was performed by using four noise reduction algorithms and word lists which take word difficulty into account, and then the word intelligibility was estimated by the proposed methodology. The results confirmed that the word intelligibility can be estimated well from the PESQ MOS without distinguishing the noise reduction algorithms and the noise types.

Objective Estimation of Word Intelligibility for Noise-Reduced Speech
It is essential to ensure a satisfactory QoS (Quality of Service) when offering a speech communication system with a noise reduction algorithm. In this paper, we propose a new obejective test methodology for noise-reduced speech that estimates word intelligibility by using a distortion measure. Experimental results confirmed that the proposed methodology gives an accurate estimate with independ...

متن کاملNoisy speech enhancement based on long term harmonic model to improve speech intelligibility for hearing impaired listeners
This study proposes a speech enhancement algorithm to improve speech intelligibility for hearing impaired listeners in adverse conditions. The proposed algorithm is based on a long term harmonic model, where the harmonics of target speech are more distinguished from noise spectrum interference. Our method consists of two stages: i) Prominent pitch estimation based on long term harmonic feature ...
