Title (EN) SPEECH RECOGNITION METHOD, DEVICE, AND SYSTEM
(FR) PROCÉDÉ, DISPOSITIF ET SYSTÈME DE RECONNAISSANCE VOCALE
(ZH) 语音识别方法、装置及系统
Abstract:
(EN) A speech recognition method, device, and system. The method comprises: constructing an acoustic WFST which is a search network from acoustic features to pronunciation attributes; constructing a pronunciation WFST which is a search network from the pronunciation attributes to phonemes; constructing a dictionary WFST which is a search network from the phonemes to characters or words; constructing a language WFST which is a search network from the characters or words to word sequences; integrating the plurality of WFSTs to generate a speech recognition WFST, performing speech recognition on the basis of the speech recognition WFST, and outputting a recognition result with the highest probability.
(FR) La présente invention concerne un procédé, un dispositif et un système de reconnaissance vocale. Le procédé comprend : la construction d'un transducteur pondéré à états finis (WFST) acoustique qui est un réseau de recherche à partir de caractéristiques acoustiques en des attributs de prononciation ; la construction d'un WFST de prononciation qui est un réseau de recherche à partir des attributs de prononciation en phonèmes ; la construction d'un dictionnaire WFST qui est un réseau de recherche à partir des phonèmes en caractères ou mots ; la construction d'un WFST de langage qui est un réseau de recherche à partir des caractères ou des mots en séquences de mots ; l'intégration de la pluralité de WFST pour générer un WFST de reconnaissance vocale, la réalisation d'une reconnaissance vocale sur la base du WFST de reconnaissance vocale et la production d'un résultat de reconnaissance ayant la probabilité la plus élevée.
(ZH) 一种语音识别方法,装置及系统。该方法包括:构建声学WFST,该声学WFST是从声学特征到发音属性的搜索网络;构建发音WFST,该发音WFST是从发音属性到音素的搜索网络;构建词典WFST,该词典WFST是从音素到字或词的搜索网络;构建语言WFST,该语言WFST是字或词到词序列的搜索网络;对上述多个WFST进行整合生成语音识别WFST,并基于该语音识别WFST进行语音识别,输出概率最大的识别结果。
