[0089] The voice chat system according to the first embodiment of the present invention will be described in detail below.

[0090] FIG. 1 is a schematic diagram showing a voice chat system according to a first embodiment. The voice chat system 10 includes a communication network 12, a search server 14, and information processing devices 20A and 20B (hereinafter sometimes collectively referred to as information processing devices 20).

[0091] The communication network 12 is a communication network that connects the information processing device 20 and the search server 14 to enable bidirectional or unidirectional communication therebetween. The communication network 12 may, for example, be composed of a public network (for example, the Internet, a telephone network, a satellite communication network, or a broadcast communication channel) or a private network (for example, a WAN (Wide Area Network), a LAN (Local Area Network), an IP-VPN (Internet Protocol-Virtual Private netw...

Abstract

The invention provides a voice chatting system, an information processing device and a words identifying method. The voice chatting system comprises: a plurality of information processing devices executing words identification at the same time of executing voice chatting; and a search server connected with the plurality of information processing devices through the communication network. The search server searches a keyword list openly to at least one information processing device, the keyword list comprises search keywords searched by the search server. At least an information processing device comprises: an identifier dictionary generating unit, which obtains the search keyword list from the search server, to generate an identifier dictionary of words used when the words are identified; and a words identifying unit, which identifies voice to the voice data obtained from the conversation during voice chatting through referring to the identification database comprising the identifier dictionary.

Description

technical field [0001] The present invention relates to a voice (voice) chat system, an information processing device, a speech (speech) recognition method, a keyword detection method and a program. Background technique [0002] Speech recognition has been studied for a long time and has become capable of providing very high accuracy recognition rates on spoken utterances. However, it is still difficult to provide high performance in recognizing natural conversations between humans. [0003] In recent years, serious research has been performed on techniques for extracting talking topics from utterances, also known as topic detection techniques. When employing topic detection techniques, the utterance recognition unit that extracts textual information from utterances plays an important role. [0004] As methods of extracting keywords from utterances, there are known a method of extracting keywords from utterances that focuses only on keywords and a method of using large-voc...
