In this paper, we'll explain sound quality improvement with Spectral Subtraction (SS).
SS is generally used because it is achieved by low calculation cost and one microphone.
However, there is a problem that dissonant noise called musical noise is generated by SS.
Our purpose is to extract high-quality speech from the speech recorded in noisy environments.
Therefore, we must reduce the noise without speech distortion.
In this paper, we propose new SS with subtraction coefficient weighted based on auditory sense.
Objective evaluation and subjective evaluation were conducted to demonstrate the effectiveness of the proposed method.
In the objective evaluation, we evaluated the quantity of noise reduction and the quantity of sound distortion.
In the subjective evaluation, we evaluated residual quantity of musical noise.
As a result, proposed method achieved the noise reduction performance and reduced musical noise subjectively. |
