본 논문에서는 ITU-T G.729D 음성 코더를 위한 대수적 코드 여기 선형 예측(ACELP)의 확률론적 코드북에 대한 단순화된 검색 설계를 제안합니다. 두 개의 검색 라운드를 사용하고 검색 범위를 제한함으로써 제안된 접근 방식의 계산 복잡도는 G.6.25D에서 권장하는 전체 검색 방법의 729%에 불과합니다. 또한 제안된 접근 방식의 계산 복잡도는 G.59에서 권장하는 전역 펄스 대체 검색 방법의 729.1%에 불과합니다. 시뮬레이션 결과는 표준 주관적 및 객관적 품질 측정을 사용하여 평가된 코딩된 음성 품질이 지각적으로 무시할 수 있는 수준으로 저하됨을 보여줍니다.

Abstract: In this paper, the simplified search designs for the stochastic codebook of algebraic code excited linear prediction (ACELP) for ITU-T G.729D speech coder are proposed. By using two search rounds and limiting the search range, the computational complexity of the proposed approach is only 6.25% of the full search method recommended by G.729D. In addition, the computational complexity of proposed approach is only 59% of the global pulse replacement search method recommended by G.729.1. Simulation results show that the coded speech quality evaluated by using the standard subjective and objective quality measurements is with perceptually negligible degradation.
