Speech processing device

Abstract

To ensure that speech recognition is performed without being accompanied by operation of a forward trigger. The system includes a speech / non-speech discrimination section 5 which discriminates whether the sound inputted from a speech input section 3 is speech or non-speech, a keyword dictionary 10, a dictionary 13 for speech recognition, a speech recognition section 8 which performs speech recognition based on the dictionary 13 for speech recognition, a speech keyword detection section 11 which detects whether the sound judged to be the speech in the speech / non-speech discrimination section 5 is a word previously registered in the keyword dictionary 10 or not, and a recognition instruction section 9 which emits the instruction to perform the speech recognition of the sound inputted at the time the sound inputted from the speech input section 3 is detected to be the sound including a word registered in the keyword dictionary 10 to the speech recognition section 8. The speech recognition is performed using the specific utterance after the user utters a desired word as a trigger.

Description

technical field [0001] The invention relates to a voice processing device, which can perform voice recognition and speaker recognition, and is used to control various devices through voice. Background technique [0002] In general, in voice processing for voice recognition and speaker recognition, there is a problem of misrecognition caused by picking up surrounding environmental voices in addition to target voices. In order to eliminate such a disadvantage, Patent Document 1 below discloses a technique of operating a button by voice before the user utters a target language. This technology is generally referred to as push-to-talk. In addition, Patent Document 2 below discloses a technique for solving the problem by uttering a specific keyword instead of the voice operation button disclosed in Patent Document 1. This technique is to wait for a word to become a keyword and obtain information after the word is recognized, which is called a voice command (magic word) method. ...

AI Technical Summary

Problems solved by technology

However, as mentioned above, the utterance of the target language after the front trigger such as the operation of the voice operation button and the utterance of the keyword requires accurate utterance as described above. Therefore, the speaker is aware of this and becomes nervous, causing the speech to be unsmooth. or high probability of being wrong

Therefore, it is difficult to avoid misrecognition due to the user's utterance
