In the embodiment of the present invention, the 4th voice signal more than preset duration can be received by microphone, wherein, the 4th
Voice signal can be the voice signal that user sends, and preset duration includes at least one basic duration unit, basic duration list
The time span of member can be that user pre-sets or system is pre-set.Basic duration unit can be 500
Millisecond (ms), 600 milliseconds (ms), 800 milliseconds (ms) etc..For example, if preset duration is 500ms, basic duration unit is
500ms, a length of 1000ms during four voice signals, then the 4th voice signal duration exceed preset duration, preset duration includes one
Individual basic duration unit；If preset duration is 1000ms, basic duration unit is 500ms, a length of during four voice signals
1000ms, then the 4th voice signal duration exceed preset duration, preset duration includes two basic duration units；If preset duration
For 1000ms, basic duration unit is 500ms, a length of 1200ms during four voice signals, then the 4th voice signal duration exceedes
Preset duration, preset duration include two basic duration units.
S305, decibel value of the 4th voice signal of measurement in each basic duration unit.
In the embodiment of the present invention, for example, if preset duration is 1000ms, basic duration unit is 500ms, the 4th language
A length of 1000ms during sound signal, then preset duration include two basic duration units, the first basic duration unit is 0-500ms,
Second basic duration unit is 500-1000ms, and decibel value of the 4th voice signal of measurement in the first basic duration is first point
Shellfish value, decibel value of the 4th voice signal of measurement in the second basic duration is the second decibel value；If preset duration is 1000ms,

Rotary speed corresponding to shellfish value, the rotary speed as corresponding to the decibel value in each basic duration unit rotate the camera.
In the embodiment of the present invention, decibel value is with including the corresponding of decibel value and rotary speed in the corresponding lists of rotary speed
Relation, for example, when decibel value is less than 10 decibels (dB), corresponding rotary speed is 0, right when decibel value is 10-20 decibels (dB)
The rotary speed answered is 0.1 radian per second (0.1rad/s)；When decibel value is 20-30dB, corresponding rotary speed be 0.2 radian/
Second (0.2rad/s)；When decibel value is 30-40 decibels (dB), corresponding rotary speed is 0.3 radian per second (0.3rad/s)；Point
When shellfish value is 40-50 decibels (dB), corresponding rotary speed is 0.4 radian per second (0.4rad/s)；Decibel value is 50-60 decibels
(dB) when, corresponding rotary speed is 0.5 radian per second (0.5rad/s)；When decibel value is 60-70 decibels (dB), corresponding rotation
Rotary speed is 0.6 radian per second (0.6rad/s)；When decibel value is 70-80 decibels (dB), corresponding rotary speed be 0.7 radian/
Second (0.7rad/s)；When decibel value is more than 80 decibels (dB), corresponding rotary speed is 1 radian per second (1rad/s).Citing comes
Say, if preset duration is 1000ms, basic duration unit is 500ms, a length of 1000ms during four voice signals, then preset duration
Including two basic duration units, the first basic duration unit is 0-500ms, and the second basic duration unit is 500-1000ms,
It is the first decibel value to measure decibel value of the 4th voice signal in the first basic duration, and the 4th voice signal of measurement is in the second base
Decibel value in this duration is the second decibel value, if the first decibel value is 45 decibels (dB), corresponding rotary speed is 0.4 arc
Degrees second, the second decibel value are 65 decibels (dB), and corresponding rotary speed is 0.6 radian per second, then in first 500ms, presses
The speed rotating camera of 0.4 radian per second, in second 500ms, by the speed rotating camera of 0.6 radian per second.
S307, the second voice signal for including the second class keyword is received, the second class pass is extracted from the second voice signal
Key word.
