Description

A method of improving kettle phonetic recognization rate
Technical field
The present invention relates to a kind of sound control method technical field, especially a kind of side for improving kettle phonetic recognization rate Method.
Background technique
Kettle with voice control function can be controlled by acquiring the voice command of user, be mentioned significantly The high property easy to use of kettle；But kettle in the prior art is when heating up water, especially when to be greater than 50 Celsius for water temperature When spending, kettle phonetic recognization rate is lower, to seriously affect the application experience of consumer.This is because local heating Water the phenomenon that will appear a large amount of bubble eruptions, which can achieve 85dB or more inside kettle, and due to burning The voice recognition unit of kettle is closer with heating unit --- and usually less than 40 centimetres, therefore produced by the water of local heating A large amount of bubble eruption noises, can severe jamming kettle speech identifying function.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of method for improving kettle phonetic recognization rate, energy Enough overcome a large amount of bubble eruption noises caused by the water of local heating, is done caused by the speech identifying function to kettle It disturbs.
The technical solution adopted by the present invention to solve the technical problems is:
A method of improving kettle phonetic recognization rate, comprising the following steps:
S1: kettle speech control system enters wake-up states after recognizing wake-up word；
S2: speech control system judges whether kettle is in heated condition, if kettle is in heated condition, voice Control system reduces heating power or the pause heating of kettle；
S3: speech control system recognition command word simultaneously works according to the corresponding requirement of order word；
S4: speech control system exits wake-up states.
As a further improvement of the above technical scheme, in step S2, speech control system obtains in kettle simultaneously Current water temperature:
If kettle is not at heated condition, speech control system is directly entered to be operated in next step；
If kettle is in heated condition and current water temperature is more than set water temperature, speech control system reduces kettle Heating power or pause heating；
If kettle is in heated condition and current water temperature is no more than set water temperature, speech control system is directly entered down Single stepping.
As a further improvement of the above technical scheme, the set water temperature is 50 degrees Celsius.
As a further improvement of the above technical scheme, in step S3, before speech control system recognition command word first Delay waiting is carried out, so that underwater bubble pop-noise is faded away in order to set aside some time.
As a further improvement of the above technical scheme, in step S3, speech control system plays joyous when being delayed and waiting Meet prompt tone.
As a further improvement of the above technical scheme, in step S2, if kettle is in heated condition, voice control System records the current heated condition parameter of kettle first, then reduces heating power or the pause heating of kettle；
In step S3, speech control system fails to recognize effective order word, and voice control system within the set time There is the heated condition parameter of record in system, then kettle works on according to the heated condition parameter of record, while removing record Heated condition parameter.
A kind of method improving kettle phonetic recognization rate provided by the present invention is compared with prior art, beneficial Effect is:
Due to wake up word be it is fixed, such as " small to reach ", adjusted by certain special training and compatibility, even if making an uproar It is also easily identified in the environment of sound；But the voice command words substantial amounts of specific function, and Human Natural Language can not be complete Prediction, if each word requires to carry out special training and compatibility adjusting mentions the development cost that will lead to product at several times It rises；So reducing heating power or pause heating can make speech recognition be in relative to peace and quiet after identifying wake-up word Scene, to greatly improve the success rate of speech recognition.
Specific embodiment
The present invention is further described combined with specific embodiments below.
A kind of method improving kettle phonetic recognization rate provided by the present embodiment, comprising the following steps:
S1: kettle speech control system enters wake-up states after recognizing wake-up word.
S2: speech control system judges whether kettle is in heated condition, while obtaining the current water temperature in kettle:
If kettle is not at heated condition, speech control system is directly entered to be operated in next step；
If kettle is in heated condition and current water temperature is more than set water temperature, speech control system reduces kettle Heating power or pause heating；Preferably, the set water temperature is 50 degrees Celsius；
If kettle is in heated condition and current water temperature is no more than set water temperature, speech control system is directly entered down Single stepping.
S3: speech control system recognition command word simultaneously works according to the corresponding requirement of order word；
Further, delay waiting is carried out first before speech control system recognition command word, make in order to set aside some time Underwater bubble pop-noise fades away；
Further, speech control system plays welcome prompt sound when being delayed and waiting.
S4: speech control system exits wake-up states.
In addition, in step s 2, if kettle is in heated condition, speech control system records working as kettle first Then preceding heated condition parameter reduces heating power or the pause heating of kettle；
Then in step s3, speech control system fails to recognize effective order word, and voice within the set time There is the heated condition parameter of record in control system, then kettle works on according to the heated condition parameter of record, while clear Except the heated condition parameter of record.
In conclusion a kind of method for improving kettle phonetic recognization rate provided by the present embodiment, makes voice control system System has two states: wake-up states and non-wake-up states.
User can make kettle enter wake-up states by reading aloud wake-up word under non-wake-up states；It is used under wake-up states Family can read aloud the voice command words of specific function, select to heat up water or keep the temperature, cook congee or specify tealeaves category etc., to control burning Kettle carries out specified movement.
Kettle be in heating process recognize wake up word after, read current water temperature, if be higher than 50 degrees Celsius, reduce Heating power or temporary close heating, and welcome prompt sound is played, into wake-up states；Since heating is slowed down, underwater bubble is quick-fried Splitting phenomenon can fade away, and be delayed caused by welcome prompt sound with playing, and the interference of underwater bubble pop-noise also declines therewith, Phonetic recognization rate will be greatly improved at this time.
After speech recognition is completed and obtains accordingly result, kettle works according to the requirement that user specifies；If into Enter unidentified accordingly result after wake-up states, then the task before kettle restores.
Better embodiment of the invention is specifically described above, certainly, the present invention can also using with it is upper The different form of embodiment is stated, those skilled in the art are made equivalent on the premise of without prejudice to spirit of the invention Transformation or corresponding change, all should belong in protection scope of the present invention.
