and when the current target area is broadcasted, setting the next target area as the current target area, and re-entering the execution step until all the areas to be broadcasted are broadcasted.
The method further comprises the following steps of configuring a voice broadcast speed value, wherein the voice broadcast speed value comprises a voice broadcast speed fluctuation value and a voice broadcast speed fluctuation value;
in the executing step, the method further comprises the following steps of judging a comparison value between the voice broadcast speed reference value and the voice broadcast speed range: if the voice broadcast reference value is in the voice broadcast speed range, further judging a difference value between the voice broadcast speed reference value and the current voice broadcast speed value, if the difference value is smaller than the voice broadcast speed fluctuation value, maintaining the current voice broadcast speed value unchanged, and otherwise, setting the voice broadcast speed reference value as the voice broadcast speed value.
Preferably, the voice broadcast speed fluctuation value is 10-12 words/minute.
Preferably, the initial value of the voice broadcasting speed is 130 words/minute.
The further technical proposal is that the step of calculating the voice broadcast speed reference value is that,
the voice broadcast speed reference = the broadcast content word count/(distance of the current target area/robot moving speed).
Preferably, the maximum value of the voice broadcast speed is 250 words/minute, and the minimum value is 80 words/minute.
The method for adjusting the voice broadcasting speed indoors according to the moving distance can solve the problem that when a long-distance target passes through, if the voice broadcasting speed is too fast, a user obtains voice information too fast; when passing through the short distance target, if voice broadcast is too slow, the user obtains the incomplete problem of voice message. According to the invention, the corresponding voice broadcasting speed can be matched according to different distance targets, and the user experience is improved.
Drawings
Fig. 1 is a schematic flow diagram of a method for adjusting a voice broadcast speed indoors according to a moving distance according to the present invention.
Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1, the method for adjusting the speed of voice broadcast indoors according to the moving distance includes the following steps:
a configuration step:
setting a voice broadcasting speed range, and setting a maximum value and a minimum value of a voice broadcasting speed; wherein, the maximum value of the voice broadcasting speed is set to 250 words/minute, and the minimum value is set to 80 words/minute. Further, the method also comprises the steps of setting an initial value of a voice broadcasting speed value, wherein the initial value of the voice broadcasting speed is set to 130 words/minute in the embodiment; and setting a voice broadcast speed fluctuation value, wherein the voice broadcast speed fluctuation value is 10-12 words/minute and is set to 10 words/minute in the embodiment. The speech rate is adjusted through voice playing, hardware equipment such as a frequency modulator, an amplifier and a delayer can be damaged through frequent adjustment, the frequent adjustment of the speech rate is avoided on the premise that the adjustment requirement is met, and the service life of hardware is prolonged. The voice broadcast speed fluctuation value range is set, so that when broadcasting, if the difference between the prior broadcast speed (namely the current voice broadcast speed value) and the theoretical broadcast speed (namely the voice broadcast speed reference value) is not large, the actual broadcast speed is not regulated, the loss of hardware is reduced, and meanwhile, the actual information receiving is not influenced. The speed of 130 words/minute is the normal hearing acceptance speed of human beings, and the speed is used as an initial value, so that the voice regulation requirement can be effectively met, and the service life of hardware is guaranteed.
The execution steps are as follows:
take the scene of using the robot to carry out voice broadcast for each office area in the office building as an example.
And acquiring the distance of the current target area, namely the length of the current office area ready for broadcasting along the advancing direction of the robot.
Calculating a voice broadcast speed reference value according to the distance of the current target area;
wherein, the voice broadcast speed reference value = broadcast content word count/(distance of the current target area/robot moving speed).
Judging a comparison value of the voice broadcast speed reference value and the voice broadcast speed range,
if the voice broadcasting reference value is within the voice broadcasting speed range, setting the voice broadcasting speed reference value as a voice broadcasting speed value;
and further, judging a difference value between the voice broadcast speed reference value and the current voice broadcast speed value, if the difference value is smaller than the voice broadcast speed fluctuation value, maintaining the current voice broadcast speed value unchanged, and otherwise, setting the voice broadcast speed reference value as the voice broadcast speed value. That is, assuming that the currently calculated voice broadcast speed reference value is 125 words/minute, the voice broadcast speed initial value is 130 words/minute, and the difference between the two values is less than the fluctuation value of 10 words/minute, the voice broadcast speed value is maintained to be 130 words/minute.
If the voice broadcasting reference value is larger than the maximum value of the voice broadcasting speed, setting the maximum value of the voice broadcasting speed as a voice broadcasting speed value;
if the voice broadcasting reference value is smaller than the minimum value of the voice broadcasting speed, setting the minimum value of the voice broadcasting speed as a voice broadcasting speed value;
and carrying out voice broadcast according to the voice broadcast speed value.
And when the broadcasting calculation of the current target area is completed, setting the next target area as the current target area, and re-entering the execution step until all the areas to be broadcasted are broadcasted. It should be noted that "completing the current target area broadcast calculation" does not refer to the moment when the robot broadcast work is completed, and even if the robot is still broadcasting, the robot can prepare the next target area, which is also understood as "completing the current target area broadcast calculation"; for example, when broadcasting office a, an execution step is completed, at this time, since the broadcasting speed is already determined, even if the robot does not actually finish current office a, the broadcasting calculation of office a can be considered to be completed, the broadcasting calculation of office B is performed, and the broadcasting can be executed according to the calculation result of office B only after the robot enters the area of office B.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
