In addition, sound characteristics, i.e., characteristics capable of identifying the sound characteristics of each person, include tone, loudness, and timbre. The command information, namely a command word representing the change of the operating state of the dishwasher in the voice characteristics of the user, comprises the state command and the broadcast command of the dishwasher. The cleaning water is a mixed solution of clean water and chemicals required in the cleaning process, wherein the chemicals required in the cleaning process generally comprise machine washing liquid and drier.

Fig. 1 shows a block diagram of a dishwasher with voice announcement and voice recognition in an embodiment of the present application.

Referring to fig. 1, the dishwasher includes a sound collection module 1010 for acquiring a sound characteristic of a user, a determination module 1020 for determining whether the sound characteristic matches a last recognized sound characteristic, a voice recognition module 1030 for recognizing command information in the sound characteristic, and a control module 1040 for controlling an operation of the dishwasher according to the command information.

By adopting the technical scheme, whether the sound characteristics acquired at the time are the same as the sound characteristics acquired before the last shutdown is judged through the judging module, and if the sound characteristics are the same, the sound acquired at the two times is from the same sound source; after judgment, the command information in the voice is identified to control the dish-washing machine to execute the voice command, so that the problem that the dish-washing machine is interfered by other sounds is solved, and the accuracy of voice control on the dish-washing machine is improved.

The sound collection module 1010, the determination module 1020, the speech recognition module 1030, and the control module 1040 are described below.

The sound collection module 1010 is connected to the judgment module 1020. The sound collection module 1010 collects audio signals around the dishwasher. It should be noted that the audio signal is a signal representing a mechanical wave, and the pitch of the sound determines the frequency of the mechanical wave; the loudness of the sound determines the vibration amplitude of the mechanical waves; the timbre of sound determines the harmonics in the mechanical waves and, therefore, the sound features are included in the audio signal. The sound collection module 1010 may collect sound using a microphone. In some embodiments, the dishwasher further comprises an analog-to-digital converter to which the sound collection module 1010 outputs the collected audio signal; the analog-to-digital converter converts the audio signal into a digital signal and outputs the digital signal to the determining module 1020.

After receiving the digital signal, the determining module 1020 compares the digital signal with the digital signal acquired before the previous shutdown to determine whether the audio signal acquired this time is the same as the audio signal acquired before the previous shutdown. If yes, it indicates that the sound source of the collected sound is the same as the sound source of the sound collected before the previous shutdown, and the determining module 1020 outputs the determination result to the voice recognition module 1030.

The voice recognition module 1030 is connected to the determination module 1020, receives the determination result of the determination module 1020, and when the determination result output by the determination module 1020 is yes, the voice recognition module 1030 stores the audio signal of this time in the form of a digital signal and recognizes command information in the audio signal. The command information comprises a status command and a broadcast command.
