Referring to Fig. 3, be embodiment of the invention controlling method and phonetic function analysis diagram.
After switch is pressed; (these six groups of combination functions are artificial the conclusion so that understand to fan work under A, B, C, D, E, six groups of combination functions of F; Be not that invention limits or the setting of embodiment's concrete function); All represent the pairing speech command of text that the user sends in the skeleton diagram, its corresponding control function is seen as shown in table 1.
Said method for using, promptly press power switch 1 after, the user need launch the A function; Then send " X shelves " (X representes one, two, three, four, five, six, seven) speech command with mandarin, voice-input unit 18 is collected voice messaging, the speech processing module of input central control unit; Form the speech vector sequence instruction; Compare with the instruction of the pre-stored voice in the storage, export corresponding speed-regulating instruction to the speed adjusting module of this phonetic order and carry out speed governing, fan starts with corresponding gear; Fan only need send that speech command " is closed " to the user or " little black " get final product (setting " little deceiving " voice, is in order to increase the effect of entertaining and amusement purely, as crying out a people, makes its something that calls it quits the same) if want to close.After the A function was launched, under the default conditions, C group functional status was " a normal wind state "; D group functional status is " removing quiet " state; The E functional status is " about pendulum-pass " " Eight characters pendulum-pass " state of " going up the bottom-passs ", and F organizes function and do not launch i.e. not timing.B group functional status has only one, is exactly when being called out " Xiao Bai " name, can make the user " " voice answer-back, play then about one section of this product introduction brief voice, play certain propaganda or advertising effect.
When the A group was in " X shelves " working state, B, C, D, E, five groups of functions of F can be used speech command operation, and were independent of each other between group.The wind speed digital display shows the gear size in real time.The real-time display environment temperature level of temperature digital display.
As change C group functional status; Can require to send speech command " nature ", " sleep ", " normally " according to environment or work and rest and can realize that the fan wind regime is " natural wind ", " sleep wind ", " normal wind "; When sending during in working order speech command, fan send " drip! " sound and LED lamp glimmer (other functional statuses are when this kind of sounding situation, and reaction is identical); When changing to different conditions, fan is used pairing functional status of speech command and the LED that user of speech play sends and is glimmered, sends " nature " order like the user, send the voice of " natural wind " with aft-fan, and the LED lamp glimmers.
As (default conditions are " removing quiet " to change D group functional status; Promptly can, various states report corresponding voice state of a control when changing); Only need send the speech command of " quiet ", any state of this aft-fan changes all no longer reports corresponding phonetic function, and only the LED lamp glimmers.If want to recover to report function, the speech command that only need send " releasing " gets final product.
As change E group functional status (default conditions are " about pendulum-passs " " the last bottom-pass " " Eight characters pendulum-pass " state), desire to make fan can about put wind, need send " about " speech command get final product; If the user send once more " about " speech command, pendulum wind function about fan will cut out.In like manner, last bottom wind voice control is the same.These two kinds of functional statuses can exist simultaneously.In addition, if send " Eight characters " speech command, fan will be operated in Eight characters ventilation state so, sees the wind of stereoeffect off; Send " 8 word " speech command once more, the fan head stops swinging.Eight characters air-supply is the aggregate motion that swings and swing up and down, thus with both incompatible existence of back, but can switch at any time.
As change F group functional status (default conditions are the non-timed state), and only need send the speech command (X is, two, three, four, five, six, seven) of " deciding X ", fan is then launched timing function, and the time is " X " hour.Only need after sending mentioned order if want to increase the half an hour or the half an hour of reducing, the speech command that sends " adding ", " subtracting " again gets final product.In addition, fan can respond new timing speech command in timing process.It should be noted that the user sends the speech command of " subtracting " when regularly remaining time was less than 30 minutes, fan will be cancelled timing function so; When need be greater than 7 hours longer timing, only need behind the speech command that sends " fixed 7 ", use the speech command of " adding " to cry out down again, it is 99 hours that length can be fixed time.
Referring to Fig. 4, be user's training program algorithm flow chart of the embodiment of the invention.
Can realize satisfying the training of the personalization of user's needs among the present invention.
The program circuit of voice training is substantially as follows: system is behind the button 8 double-click signals of undergoing training; Promptly start training program, judge that whether the pattern number N that has trained in the storage is less than 5, under less than 5 situation; Carrying out " speech data " through voice-input unit 18 gathers; Audio Processing Unit through central processing unit (CPU) 20 carries out pretreatment " end-point detection " and " digital filtering " then, and carry out " LPC " and " LPC cepstrum " afterwards and analyze, be the speech vector sequence that " model training " generates 1 speech command afterwards; Then this speech vector sequence is deposited in the storage 21; When once " End of Tape ", carry out the training of next speech command, to the last generate 28 speech vector sequences.Subsequently, the model number adds 1, one group of training completion automatically.When model number n greater than 5 the time, during training, system can wipe the data that primary training generates automatically, reserves storage space for changing time training.More than, can generate the voice training model that is no more than 5 groups for double-clicking training button 8.After " training " button is clicked, then can only store one group of training pattern, can wipe the training result of last time automatically next time when training, and its algorithm routine is the same.
The operating process of voice training is substantially as follows: startup power switch 1; Double-click or click training button 8 and (can store a plurality of models during double-click; Have only a model when clicking), the user sends 1～28 phonetic order respectively according to the prompt tone of system then, twice of every group command training.If certain twice sounding is inconsistent or system does not catch, then can repeat the training of this instruction, up to training successfully for it.Because the system voice prompting and guiding, the user is easy to accomplish training, does not have certain degree of difficulty.Language form or content when afterwards, the user just can be according to oneself training come voice have been controlled.
Because the voice training that dispatches from the factory is a phonetic feature of gathering hundreds of people, comprises men and women, old and young, so discrimination is very high, the user can control each function of fan fully very exactly under mandarin.For the fan that adopts personalized training, can meet the demands to the response accuracy of training of human; Because on the algorithm is the fuzzy algorithmic approach of unspecified person; Therefore also can respond non-training of human; Therefore but it is a little that response accuracy can descend, and the invention provides the storage space that can store 5 individual trainings, and system is contrast model one by one in identification the time; So can satisfy a plurality of people's personalization training, and response accuracy can meet the demands.
Being merely the preferred embodiment of invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
