Description
Technical field
The present invention relates to the application of a kind of intelligent sound technology in converged communication, be specifically related to intelligent voice system and implementation method in a kind of converged communication.
Background technology
From the present Research of present voice technology, technology has had very big development.Speech recognition and synthetic technology are to realize that the man machine language communicate by letter and sets up necessary two key technologies of spoken language system that have tin and say ability.They can make computer have to be similar to the same the speaking and understand the ability that the people speaks of people.
Speech recognition technology mainly comprises several aspects: voice control, electronic sound, continuous speech recognition, discontinuous speech identification and phonetic study.Mainly be to support Chinese and English at present, realize existing on the Chinese and English mixed problem some obstacles.Also be difficult to accomplish accurately aspect a large amount of vocabulary of identification and the indivedual pronunciation simultaneously.As the phonetic study of the new direction of speech recognition technology, its imitation RP of then will asking for help, its difficulty that faces are how to weigh the quality of people's imitation.
Compare with speech recognition, it is ripe that speech synthesis technique is wanted comparatively speaking, is that this field is hopeful to produce a technology of breakthrough and formation industrialization near-mid term most.Speech synthesis technique is the key that computer " is lifted up one's voice "; Present stage, the maximum progress of phonetic synthesis was can convert arbitrary text to can understand continuously natural statement output in real time, and relevant art is commonly referred to the synthetic or literary composition language conversion (TTS) of literary composition language.TTS makes that one-level realizes blending at the terminal for data communication and voice communication, and people will be hopeful when obtaining Internet information, and majorities such as Short Message Service, Email are also exported with the mode of voice with the information that text mode provides.
Along with the continuous progress of voice research, gone out numerous speech recognition developing instruments: like Microsoft Speech SDK, IBM ViaVoice etc.They all provide speech recognition and synthetic secondary developing platform; And the Speech SDK and the ViaVoice main distinction have: Speech SDK is based on com's; Only based on the windows platform; And ViaVoice is based on dynamic link library, and is only just passable with copy, and such module is also arranged on the unix platform; Speech SDK recognition result can be read from message, also can read from call back function, and ViaVoice can only read from message, in programming, must make a hide window, from this window, reads the result, and is cumbersome; It must be extension name with wav that Speech SDK requires the audio file filename of identification.But because the Speech SDK of Microsoft is fully free, it has obtained gratifying discrimination, and recognition speed is fast, and is portable good, support advantages such as multiple development language, so it is widely used in every field.
Contain speech application interface (SAPI), Microsoft's continuous speech recognition engine (MCSR) and series connection speech synthesis engine (TTS) or the like among the Speech SDK of Microsoft.Also comprise direct voice management, training guide, incident, grammer, compiling, resource, speech recognition management and Text To Speech management among the SAPI for bottom control and high degree of adaptability.Speech engine is communicated by letter with the SAPI Runtime Library through device drives interface (DDI) layer, and application program (Application) is then mutual through application programming interfaces (API) layer and SAPI.Through using these API just can carry out the software development of speech recognition and phonetic synthesis aspect.
