And when the value of the counter is zero, determining that the recognized voice commands reach the preset number, and exiting from the voice command recognition state.
Another possible implementation is described below with reference to the figures.
As another possible implementation manner, fig. 4 is a second schematic diagram of voice interaction between a user and an air conditioner according to the embodiment of the present invention, as shown in fig. 4, the user speaks a wake word "air conditioner" to make the air conditioner enter a voice instruction recognition state, and perform a voice or text response of "please" on the voice instruction spoken by the user. When the air conditioner enters the recognition state, the air conditioner starts a timer, so that the air conditioner times the time between the moment of recognizing the awakening word or the voice instruction at the last time and the current moment by using the timer to judge whether the voice instruction is recognized within the preset time. As shown in fig. 4, the preset time period is 15s, and when the air conditioner starts the timer, the initial value of the timer is set to 15s, and the countdown is started.
Furthermore, after the user speaks the first voice command "cooling mode", the air conditioner is set to cooling mode, and after the setting is completed, in response to "set to cooling mode", the timer is reset to the preset duration of 15s, and the counting down is restarted.
After the user speaks the second voice command "17 degrees", the air conditioner is set to 17 degrees, and after the setting is complete, the timer is reset to the preset duration of 15s in response to "having been set to 17 degrees" and the countdown is restarted.
After the user speaks the third voice instruction "max wind", the air conditioner is set to the maximum wind volume, and after the setting is completed, the timer is reset to the preset duration of 15s in response to "the maximum wind volume is set", and counting down is started again. And when the value of the counter is zero, determining that the voice instruction is not recognized within 15s continuously, and exiting from the voice instruction recognition state.
Still another possible implementation is described below with reference to the figures.
As another possible implementation manner, fig. 5 is a third schematic diagram of voice interaction between a user and an air conditioner according to the embodiment of the present invention, and as shown in fig. 5, the user speaks a wakeup word "air conditioner" to make the air conditioner enter a voice instruction recognition state, and perform a voice or text response of "please" on the voice instruction spoken by the user. When the air conditioner enters the recognition state, the air conditioner starts a timer and a counter, so that the air conditioner times the time between the moment of recognizing the awakening word or the voice instruction for the last time and the current moment by using the timer to judge whether the voice instruction is recognized in the preset time, and meanwhile, the air conditioner counts the recognized voice instructions by using the counter to judge whether the recognized voice instructions reach the preset number. As shown in fig. 5, the preset time period is 15s, when the air conditioner starts the timer, the initial value of the timer is set to be 15s, and the countdown is started; meanwhile, the preset number is 5, and when the air conditioner starts the counter, the initial value of the counter is set to be 5.
Furthermore, after the user speaks the first voice instruction "cooling mode", the air conditioner is set to cooling mode, and after the setting is completed, the timer is reset to the preset duration 15s in response to the "setting to cooling mode", counting down is restarted, and the counter is decremented by one, so that the value of the counter is 4.
After the user speaks the second voice command of '17 degrees', the air conditioner is set to 17 degrees, and after the setting is completed, the timer is reset to the preset time length of 15s in response to 'the setting is already set to 17 degrees', the counting down is restarted, the counter is decreased by one, and therefore the value of the counter is 3.
After the user speaks the third voice instruction "maximum wind", the air conditioner is set to the maximum wind volume, and after the setting is completed, the timer is reset to the preset duration of 15s in response to the fact that the "maximum wind volume" is set, counting down is restarted, the counter is decremented by one, and therefore the value of the counter is 2.
And when the value of the counter is zero or the value of the counter is zero, the voice instruction recognition state is exited.
