As a preferred embodiment of the present invention, the processing unit 22 is further configured to extract different speech entries from different speech sets according to the feedback command, and combine the different speech entries to generate the feedback information.
Specifically, for example, the speech set may be split and combined in N dimensions, and the speech entries in each dimension are N1, N2, …, and Nn, respectively.
When the prior art is utilized to transmit the voice set, the number P of the played words needing to be stored is as follows:
P＝N1×N2×…×Nn-1×Nn。
the invention splits and combines the voice set according to n dimensions, and the number Q of the voice entries to be stored is as follows:

For example: a certain electrical appliance is a water purifier, and the voice interaction module needs to play the residual service life information of the filter element. The filter elements comprise 5 types of PP filter elements, RO filter elements, PGP filter elements, PMP filter elements and CTO filter elements. The filter element has 11 cases of zero percent, ten percent, twenty percent, … percent and one hundred percent of service life. If the speech entries in the speech set are split and combined in a matrix form, only 16 speech entries need to be stored in the play lexicon, and the speech entries corresponding to the code numbers of the speech entries are shown in table 1.
Compared with the existing voice control method, the voice control method of the invention saves the number of the entries of the voice, namely P-Q (5 multiplied by 11) - (5+11) ═ 39.
Preferably, a matrix type splitting and combining mechanism of the voice set is adopted, so that the storage space in the voice interaction module is greatly saved.

As a specific embodiment, the voice interaction module allows to transmit n voice entries at most once (n is more than or equal to 1, n belongs to Z +), and the voice interaction module plays the voice entries according to the sequence of NO:1, 2, 3, … n, and the interval time between the two voice entries is about t seconds (t is more than or equal to 0, n belongs to R +). And if the previous voice entry is not played and a new voice entry is identified, stopping playing the original voice entry and starting playing the new voice entry. It can be added that the playing interval time of the two preceding and following speech entries is defined as 0.5 second.
In a preferred embodiment of the present invention, the request instruction and the response instruction each include an invalidation command. The invalidate command is specified as 0.
It can be supplemented that, when the control module 3 instructs the voice interaction module 2 to send the feedback command by the request for the first time, the feedback command adopts an invalid feedback command, and the invalid feedback command is defined as 0.
As a preferred embodiment of the present invention, the electrical device 1 further includes a load 4, the control module 3 is connected to the load 4, and the control module 3 controls the operation of the load 4 according to the voice command.
It can be added that the electrical appliance must ensure that the control module 3 wakes up the electrical appliance by a wake-up command before responding to a command other than a voice command, and receives a valid voice command of the voice module within a prescribed wake-up holding time.
The awakening process of the electrical equipment comprises the following steps:
s10, detecting whether an awakening command is received by the electrical equipment; when a wake-up command is detected, entering a wake-up mode;
s11 and then detecting whether the wake-up time reaches the wake-up hold time,
if yes, returning to S11;
if not, detecting whether a feedback command or a voice command is received;
if the feedback command or the voice command is received, judging whether the feedback command or the voice command is effective;
