  • Voice recognition system having articulated talk-back feature
    Patent number: 8209177
    Abstract: A voice recognition system is provided that outputs a talk-back voice in a manner such that a user can distinguish the accuracy of a voice-recognized character string more easily. A voice recognition unit performs voice recognition on a user's articulation in which a character string such as the telephone number “024 636 0123” is entered via a microphone. Based on each “sound existing period delimited by silent intervals,” each recognized partial character string “024”, “636” and “0123” is obtained. A talk-back voice data generating unit connects each recognized partial character string “024”, “636” and “0123” together in a manner such that space characters are inserted, and generates a character string “024 636 0123”. The generated character string “024 636 0123” is supplied to a voice generating device as talk-back voice data. A voice signal to be produced by the speaker is generated in the form of the talk-back voice.
