MBE 부호화용 스펙트럼 V-UV 구간 검출에 관한 연구
On a Detection of V-UV Segments of Speech Spectrum for the MBE Coding
초록
In the area of speech vocoder systems, the MBE vocoder allows the high quality and low bit rate. In the MBE parameters detection, the dicision methods of V/UV region proposed until now are dependent highly to the other parameters, fundamental frequency and formant information. In this paper, thus, we propose a new V/UV detection method that uses a zero-crossing rate of flatten harmonices spectrum. This method can reduce the influences of the other parameters for the V/UV regions detection.
