F 0 윤곽의 탈억양의 이차 가중된 회귀의 이들 가중치는 반-유성음 자음에 대해 유성음 피치 윤곽을 보존하기 위하여 피치 윤곽의 유성음/무성음 세그먼트를 강조/덜 강조하도록 고안된다. 상기 메커니즘의 이점은, 음성 세그먼트화에 약간의 에러가있을지라도, 온-라인 신호 전처리 전치로서의 역할을 하는, F 0 윤곽의의 예상 적응-전정 트레이스백을 지닌 이들 가중치는 자음의 피치 윤곽에 대한 모음의 피치 윤곽을 보존할 것이다. 상기 성조 특징의 이러한 모음-보존 특성은 음성 세그먼트화 에러에 기인한 편중 추정으로부터 모델 파라미터를 보호하는 능력을 가진다.
