摘要： This application discloses a method implemented of recognizing a keyword in a speech that includes a sequence of audio frames further including a current frame and a subsequent frame. A candidate keyword is determined for the current frame using a decoding network that includes keywords and filler words of multiple languages, and used to determine a confidence score for the audio frame sequence. A word option is also determined for the subsequent frame based on the decoding network, and when the candidate keyword and the word option are associated with two distinct types of languages, the confidence score of the audio frame sequence is updated at least based on a penalty factor associated with the two distinct types of languages. The audio frame sequence is then determined to include both the candidate keyword and the word option by evaluating the updated confidence score according to a keyword determination criterion.

摘要： Methods and computer systems for audio search on a social networking platform are disclosed. The method includes: while running a social networking application, receiving a first audio input from a user of the computer system, the first audio input including one or more search keywords; generating a first audio confusion network from the first audio input; determining whether the first audio confusion network matches at least one of one or more second audio confusion networks, wherein a respective second audio confusion network was generated from a corresponding second audio input associated with a chat session of which the user is a participant; and identifying a second audio input corresponding to the at least one second audio confusion network that matches the first audio confusion network, wherein the identified second audio input includes the one or more search keywords that are included in the first audio input.

摘要： Systems and methods are provided for speech recognition. For example, audio characteristics are extracted from acquired voice signals; a syllable confusion network is identified based on at least information associated with the audio characteristics; a word lattice is generated based on at least information associated with the syllable confusion network and a predetermined phonetic dictionary; and an optimal character sequence is calculated in the word lattice as a speech recognition result.

摘要： A method is implemented at a computer to determine that certain information content is composed or compiled in a specific language selected among two or more similar languages. The computer integrates a first vocabulary list of a first language and a second vocabulary list of a second language into a comprehensive vocabulary list. The integrating includes analyzing the first vocabulary list in view of the second vocabulary list to identify a first vocabulary sub-list that is used in the first language, but not in the second language. The computer then identifies, in the information content, a plurality of expressions that are included in the comprehensive vocabulary list, and a subset of expressions that are included in the first vocabulary sub-list. Upon a determination that a total frequency of occurrence of the subset of expressions meets predetermined occurrence criteria, the computer determines that the information content is composed in the first language.
摘要翻译： 在计算机上实现一种方法来确定某些信息内容是以两种或多种类似语言中选择的特定语言来组合或编译的。 计算机将第一语言的第一词汇列表和第二语言的第二词汇列表集成到综合词汇列表中。 该集成包括根据第二词汇列表分析第一词汇列表以识别在第一语言中使用的第一词汇子列表，而不是第二语言。 然后，计算机在信息内容中识别包括在综合词汇列表中的多个表达式以及包括在第一词汇子列表中的表达式的子集。 在确定表达子集的总出现频率满足预定出现标准的情况下，计算机确定信息内容以第一语言组成。

摘要： Methods and computer systems for audio search on a social networking platform are disclosed. While running a social networking application, a computer system receives a first audio input from a user of the computer system and then generates a first audio confusion network from the first audio input. After comparing the first audio confusion network with one or more second audio confusion networks, each corresponding to a second audio input associated with one of a plurality of participants of a chat session of the social networking application, the computer system identifies at least one second audio input corresponding to the at least one second audio confusion network that matches the first audio confusion network and displays a portion of the chat session including a visual icon representing the identified second audio input on a display of the computer system.
