Description
Technical field
Voice control technology field of the present invention, in particular to a kind of voice control optimization method.
Background technique
It listens and says, be the essential attribute of communication possessed by people.Correspondingly, intelligent wearable device be also required to it is basic
Communication ability can be said, can also be listened.The listening and speaking ability of intelligent wearable device is passed by the acoustics of two kinds of input and output
Sensor is completed.The former, acquires sound by microphone input sensor；The latter is broadcast by loudspeaker output transducer
Sound reproduction sound.It in general will not only include a kind of simple sound by the collected sound of common microphone, but voice,
The mixture of musical sound and various ambient sounds (noise).And many service (voices provided by intelligent wearable device
Wake up, speech recognition, voice communication, music etc.) completion, often only depend on the vocal sections of mixed sound, and
It is the voice of equipment wearer, ambient sound in addition to this, the presence of the voice of non-wearer and other noise contributions, instead
It can hinder the normal operation of certain services.Therefore, intelligent wearable device needs an acoustics front end subsystem, to complete externally
The acquisition and relevant treatment of boundary's sound, provide effective audio data to the greatest extent, to guarantee the various function services moulds in rear end
The normal operation of block.
Summary of the invention
The present invention is directed to solve at least one of the technical problems existing in the prior art or related technologies.For this purpose, of the invention
A purpose be to propose a kind of voice control optimization method.
To achieve the above object, the present invention provides a kind of voice control optimization methods, pass through speech recognition system (ASR)
The processing collected voice signal of audio signal reception device obtains command signal, realizes the voice to smart machine according to described instruction signal
Control characterized by comprising
Preprocessed audio generates digital audio, generates efficient voice instruction, plays answer statement.
Preferably, the preprocessed audio refers to by receiving audio signal, enters institute's predicate in the audio signal
Before sound identifying system (ASR), acoustic filtering is carried out to the audio signal, obtains preprocessed audio；
In any of the above-described scheme preferably, the preprocessed audio is acquired by microphone, is filtered by analog circuit
Digital audio is generated by analog-to-digital conversion afterwards；
In any of the above-described scheme preferably, the digital audio generates effective language via speech recognition system (ASR)
Sound instruction；
In any of the above-described scheme preferably, it after terminal check receives efficient voice instruction, is controlled in current speech
Answer statement corresponding with efficient voice instruction, and the answer statement found described in broadcasting are searched in theme.
In any of the above-described scheme preferably, the acoustic filtering is by mechanical mechanism and/or acoustic construction to sky
Between domain voice signal carry out noise reduction process.
The beneficial effect that the present invention obtains is: completing to extract filtering/shaping/noise restraint of effective sound element
The voice and other noise contributions of the voice of wearer, filtering environmental noise and non-wearer, improve smart machine to voice
The discrimination of instruction.
Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.
Specific embodiment
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, still, the present invention may be used also
To be implemented using other than the one described here other modes, therefore, protection scope of the present invention is not by described below
Specific embodiment limitation.
A kind of voice control optimization method handles the collected sound of audio signal reception device by speech recognition system (ASR) and believes
Number command signal is obtained, the voice control to smart machine is realized according to described instruction signal characterized by comprising
Preprocessed audio generates digital audio, generates efficient voice instruction, plays answer statement.
In the present embodiment, the preprocessed audio refers to by receiving audio signal, enters institute in the audio signal
Before stating speech recognition system (ASR), acoustic filtering is carried out to the audio signal, obtains preprocessed audio；
In the present embodiment, the preprocessed audio is acquired by microphone, is turned after analog circuit filters by modulus
Change generation digital audio；
In the present embodiment, the digital audio generates efficient voice instruction via speech recognition system (ASR)；
In the present embodiment, terminal check receive efficient voice instruction after, current speech control theme in search with
The efficient voice instructs corresponding answer statement, and the answer statement found described in broadcasting.
In the present embodiment, the acoustic filtering is to be believed by mechanical mechanism and/or acoustic construction the sound of spatial domain
Number carry out noise reduction process.
The beneficial effect that the present invention obtains is: completing to extract filtering/shaping/noise restraint of effective sound element
The voice and other noise contributions of the voice of wearer, filtering environmental noise and non-wearer, improve smart machine to voice
The discrimination of instruction.
Again through mould after being pre-processed by acoustic filtering to collected acoustic signals according to above-described embodiment present invention
Quasi- circuit and/or digital circuit carry out subsequent filtering processing, are effectively inhibited to collected noise contribution, pass through ASR/
NLP system substantially increases the accuracy of speech recognition to effective phonetic order is identified in more pure voice signal,
To ensure the offer of high-quality service.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
