The method for improving the voice recognition rate of the water boiling kettle can overcome the defect of interference on the voice recognition function of the water boiling kettle caused by a large amount of bubble burst noise generated by locally heated water.
Description
Technical Field
The invention relates to the technical field of voice control methods, in particular to a method for improving the voice recognition rate of a kettle.
Background
The water boiling kettle with the voice control function can be controlled by collecting voice commands of a user, so that the use convenience of the water boiling kettle is greatly improved; however, when the water boiling kettle in the prior art is used for boiling water, particularly when the water temperature is higher than 50 ℃, the voice recognition rate of the water boiling kettle is low, so that the application experience of consumers is seriously affected. This is due to the fact that the locally heated water is subject to a large number of bubble bursts, which can reach over 85dB inside the kettle, and due to the fact that the voice recognition unit of the kettle is relatively close to the heating unit, typically less than 40 cm, the large number of bubble bursts generated by the locally heated water can seriously interfere with the voice recognition function of the kettle.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a method for improving the voice recognition rate of the kettle, which can overcome the interference to the voice recognition function of the kettle caused by a large amount of bubble burst noise generated by locally heated water.
The technical scheme adopted for solving the technical problems is as follows:
a method of improving the speech recognition rate of a kettle comprising the steps of:
s1: after recognizing the wake-up word, the voice control system of the kettle enters a wake-up state;
s2: the voice control system judges whether the water boiling kettle is in a heating state or not, and if the water boiling kettle is in the heating state, the voice control system reduces the heating power of the water boiling kettle or pauses heating;
s3: the voice control system recognizes the command word and works according to the corresponding requirement of the command word;
s4: the voice control system exits the awake state.
As a further improvement of the above technical solution, in step S2, the voice control system simultaneously obtains the current water temperature in the water kettle:
if the kettle is not in a heating state, the voice control system directly enters the next operation;
if the water boiling kettle is in a heating state and the current water temperature exceeds the set water temperature, the voice control system reduces the heating power of the water boiling kettle or pauses heating;
if the water boiling kettle is in a heating state and the current water temperature does not exceed the set water temperature, the voice control system directly enters the next operation.
As a further improvement of the above technical solution, the set water temperature is 50 ℃.
As a further improvement of the above technical solution, in step S3, the voice control system first performs delay waiting before recognizing the command word, so as to reserve time to make the bubble burst noise in the water gradually disappear.
As a further improvement of the above technical solution, in step S3, the voice control system plays the welcome prompt when waiting for delay.
As a further improvement of the above technical solution, in step S2, if the water kettle is in a heating state, the voice control system first records the current heating state parameter of the water kettle, and then reduces the heating power of the water kettle or pauses the heating;
in step S3, the voice control system fails to recognize the valid command word within the set time, and the voice control system has the recorded heating state parameters, so that the kettle continues to operate according to the recorded heating state parameters, and simultaneously clears the recorded heating state parameters.
Compared with the prior art, the method for improving the voice recognition rate of the kettle has the beneficial effects that:
because the wake-up words are fixed, such as 'Xiaoda', the wake-up words are easy to identify even in noisy environments through certain targeted training and compatibility adjustment; however, the number of voice command words with specific functions is huge, and human natural language cannot be completely predicted, if each word needs to be trained in a targeted manner and compatibility is adjusted, the development cost of the product is increased by several times; therefore, after the wake-up word is identified, the heating power is reduced or heating is suspended, so that the voice recognition is in a relatively quiet scene, and the success rate of the voice recognition is greatly improved.
Detailed Description
The invention will be further illustrated with reference to specific examples.
The method for improving the voice recognition rate of the kettle provided by the embodiment comprises the following steps:
s1: after recognizing the wake-up word, the voice control system of the kettle enters a wake-up state.
S2: the voice control system judges whether the water boiling kettle is in a heating state or not, and obtains the current water temperature in the water boiling kettle at the same time:
if the kettle is not in a heating state, the voice control system directly enters the next operation;
if the water boiling kettle is in a heating state and the current water temperature exceeds the set water temperature, the voice control system reduces the heating power of the water boiling kettle or pauses heating; preferably, the set water temperature is 50 ℃;
if the water boiling kettle is in a heating state and the current water temperature does not exceed the set water temperature, the voice control system directly enters the next operation.
S3: the voice control system recognizes the command word and works according to the corresponding requirement of the command word;
further, before the voice control system recognizes the command word, delay waiting is firstly carried out so as to ensure that the reserved time gradually disappears the burst noise of bubbles in the water;
still further, the voice control system plays the welcome prompt while waiting for a delay.
S4: the voice control system exits the awake state.
In addition, in step S2, if the water kettle is in a heating state, the voice control system first records the current heating state parameters of the water kettle, and then reduces the heating power of the water kettle or pauses heating;
then in step S3, the voice control system fails to recognize the valid command word within the set time, and the voice control system has the recorded heating state parameters, so that the kettle continues to operate according to the recorded heating state parameters, and simultaneously clears the recorded heating state parameters.
In summary, the method for improving the voice recognition rate of the kettle provided by the embodiment makes the voice control system have two states: an awake state and a non-awake state.
Under the non-awakening state, a user can read the awakening word to enable the kettle to enter the awakening state; under the wake-up state, the user can read the voice command words with specific functions, select to boil water or keep warm, cook porridge or designate tea products, and the like, so as to control the water boiling kettle to perform designated actions.
After identifying the wake-up word in the heating process of the water heating kettle, reading the current water temperature, if the water temperature is higher than 50 ℃, reducing the heating power or temporarily turning off the heating, playing a welcome prompt tone, and entering a wake-up state; as the heating is slowed down, the bubble burst phenomenon in the water gradually disappears, and the interference of the bubble burst noise in the water is reduced along with the time delay caused by playing the welcome prompt tone, so that the voice recognition rate is greatly improved.
After the voice recognition is completed and the corresponding result is obtained, the kettle works according to the requirement specified by the user; if the corresponding result is not identified after the kettle enters the awakening state, the working task before the kettle is restored.
While the preferred embodiments of the present invention have been illustrated and described, it is to be understood that the invention may take many forms other than those illustrated and described, and that equivalent changes and modifications can be made by those skilled in the art without departing from the spirit of the invention.
