Abstract
(EN) The present disclosure relates to the field of artificial intelligence, and in particular, to the fields of computer technology and intelligent transportation. Provided are a delay estimation adjustment method and apparatus, and a device, a storage medium and a program product. A specific implementation solution is: initializing the maximum value of a delay estimation; estimating a first delay value during a playing process of audition music; estimating a second delay value during a playing process of an audition synthetic voice; and on the basis of the first delay value and the second delay value, adjusting the maximum value of the delay estimation. By means of the present disclosure, the maximum value of a delay estimation can be adjusted in a targeted manner, thereby greatly shortening an algorithm convergence time.
(FR) La présente divulgation concerne le domaine de l'intelligence artificielle et, en particulier, les domaines de la technologie informatique et du transport intelligent. L'invention concerne un procédé et un appareil de réglage d'estimation de retard, ainsi qu'un dispositif, un support de stockage et un produit-programme. Une solution d'implémentation particulière consiste : à initialiser la valeur maximale d'une estimation de retard ; à estimer une première valeur de retard pendant un processus de lecture de musique d'audition ; à estimer une seconde valeur de retard pendant un processus de lecture d'une voix de synthèse d'audition ; et, sur la base de la première valeur de retard et de la seconde valeur de retard, à régler la valeur maximale de l'estimation de retard. Au moyen de la présente divulgation, la valeur maximale d'une estimation de retard peut être réglée de manière ciblée, ce qui permet de raccourcir considérablement le temps de convergence d'un algorithme.
(ZH) 本公开提供了时延估计调整方法、装置、设备、存储介质以及程序产品,涉及人工智能领域,尤其涉及计算机技术、智能交通领域。具体实现方案为:初始化时延估计的最大值;在试音音乐播放过程中估计第一时延值;在试音合成语音播放过程中估计第二时延值;基于第一时延值和第二时延值,调整时延估计的最大值。本公开能够针对性地调整时延估计的最大值,大大缩短算法收敛时间。
