It is overlapped with the noise information of storage, also can achieve the purpose for offsetting the first noise information in voice messaging.
In an alternative embodiment, determine that target superposition value includes following one from multiple superposition values:
In the noise classification for determining the first noise information noise information corresponding with a superposition value in multiple superposition values
The identical situation of classification under, the identical superposition value of classification is determined as target superposition value；The identical noise information of classification
More close to the first noise information.
In the noise classification for determining the first noise information noise information corresponding with a superposition value in multiple superposition values
The different situation of classification under, the minimum value in multiple superposition values is determined as target superposition value.It can be most using minimum value
The first noise information of counteracting of big degree.
In an alternative embodiment, it for the noise information constantly stored, needs determining the first noise information
Noise classification noise information corresponding with a superposition value in multiple superposition values the different situation of classification under, record the
The frequency of occurrences of one noise information；When the frequency of occurrences of the first noise information reaches the second preset threshold, the first noise is stored
The noise classification of information and the sound wave of the first noise information.
In the present embodiment, the value of the first preset threshold and the second preset threshold can be identical, for example, 3 times, it can also
To be different.

Voice messaging；Memory, for storing multiple noise informations；Processor, for by the sound wave of the first noise information respectively with deposit
The sound wave of multiple noise informations of storage is overlapped, and obtains multiple superposition values；Target superposition value is determined from multiple superposition values；Benefit
The first noise information is removed with target superposition value, obtains target voice information, controls household appliance using target voice information.
It should be noted that voice capture device can be microphone array.
It should be noted that further including speech comparison unit in household appliance, for comparing the first noise information and storage
Multiple noise informations whether match.Wireless communication module is connect with server, for storing processing result to server,
Or voice messaging is handled in the server.
In the present embodiment, the method for household appliance concrete sound noise reduction is as follows: microphone array timing acquisition works as front ring
Border audio data.Pass through the environment in speech comparison unit statistical comparison current environmental audio data and ambient sound storage unit
Sound data update, record frequency of occurrences highest or the maximum environmental audio data of noise (are equivalent to and deposit to ambient sound storage unit
Reservoir) in.
It should be noted that speech comparison unit, ambient sound storage unit may be present in local or server end.
It pays the utmost attention to be made an uproar with the environment in ambient sound storage unit when the processing unit processes voice stream data of voice messaging
Signal to noise ratio is to noise reduction.
