VOICE TRANSMISSION QUALITY MEASUREMENT BASED ON WAVELET TRANSFORMATION
Tomáš Dresler, Jan Holub, Radislav Šmíd
Abstract:
A new method for objective voice quality measurements is described in the article. It is based on wavelet transformation that enables intrinsically also time localisation of eventual impairments. In comparison with other methods (based on P.861 and P.862 algorithms), the described method saves about one half of operations needed for achievement of comparable results, thus saving computation power and time.
