Enhancement of degraded speech by removing dissonant components
Sadil, Jiří ; Míča, Ivan (referee) ; Smékal, Zdeněk (advisor)
This work deals with the method of partial removal of interference from the speech signal, thereby improving the overall quality of depreciated speech signal and improve signal-to-noise ratio. Specifically, the elimination of frequent disturbance, such as crosstalk from other interviews, noise, car noise, computer fans wind coming to the microphone and general noise. The method described below is based on frequency filtering, which can be thought of as the discordant tones of intervals. The size range of discordant phenomena, be applied to the basic tone of speech, which can be thought of as a tone tempered tuning C, and thus a spectrum of dissonant speech appear as notes F #, B, and C #. The aim of my work is finding its own working methods and technical solutions for realization of removing the greatest proportion of interfering components in the signal deteriorated by filtration discordant elements.
