[0029] In this embodiment, a method for preventing a speaker and a microphone from interfering with each other is provided, which runs on a mobile terminal, a computer terminal or a similar computing device. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] Figure 2 FIG. 1 is a flow chart of a method for preventing a speaker and a microphone from interfering with each other according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0031] Step S201, receiving and responding to a wake-up instruction to wake up the voice system, and after waking up the voice system, controlling the microphone to be turned off and the speaker to be turned on, so that the speaker plays a response voice;

[0032] In the above, the voice system is awakened in response to the voice indication.

[0033] Specifically, there are valid wake-up commands in the voice system. Users can issue commands through the wake-up commands in the vocabulary. The voice system performs corresponding operations by recognizing keywords, thereby achieving the effect of controlling the product using voice. After the user outputs the wake-up command specified in the vocabulary, the voice control system program is awakened and started.

[0034] Before receiving and responding to a wake-up instruction to wake up the voice system, the method further includes: controlling the wake-up voice system to be in a waiting state, in which the speaker is in a turned-off state and the microphone is in a standby state.

[0035] Step S202, after the above-mentioned speaker plays the above-mentioned response voice, control the above-mentioned speaker to be turned off and control the above-mentioned microphone to be turned on to wait for receiving the actual voice instruction. If the above-mentioned actual voice instruction is received within the preset time period, control the above-mentioned microphone to be turned off and control the above-mentioned speaker to be turned on. If the above-mentioned actual voice instruction is a valid voice instruction, execute the above-mentioned actual voice instruction and control the above-mentioned speaker to play the execution result.

[0036] Specifically, there are multiple voice commands in the voice system vocabulary, and keyword matching technology can be used to determine whether the actual voice command is a valid voice command.

[0037] Specifically, the actual voice commands include: turn on the lights in the room, turn off the lights in the room, increase the brightness of the lights, reduce the brightness of the lights, turn on the air conditioner, turn off the air conditioner, set the air conditioner temperature to 25 degrees Celsius, switch the air conditioner to energy-saving mode, turn on the dehumidification function of the air conditioner, turn on the TV, turn off the TV, increase the volume of the TV, display the current temperature of the refrigerator, open the curtains, close the curtains, adjust the curtains to half-open, etc.

[0038] In addition, the actual voice command may also include some combined commands, for example, turning on the main light while turning on the air conditioner in the living room, turning on the humidifier in the bedroom while turning on the air conditioner in the bedroom, and so on.

[0039] The method of preventing the speaker and the microphone from interfering with each other in the present application wakes up the voice system by receiving and responding to the wake-up command, and after waking up the voice system, controls the microphone to be turned off and the speaker to be turned on, so that the speaker plays the response voice; after the speaker plays the response voice, controls the speaker to be turned off and the microphone to be turned on to wait for receiving the actual voice command, and if the actual voice command is received within a preset time period, controls the microphone to be turned off and the speaker to be turned on, and if the actual voice command is a valid voice command, executes the actual voice command and controls the speaker to play the execution result. By turning the microphone and the speaker on and off respectively in the stages before and after command reception and command reply, the two parts are in a mutually shielded state and will not work at the same time, thereby avoiding mutual interference between the parts during the working process.

[0040] Furthermore, the method further includes: if the actual voice command is not received within the preset time period, controlling the wake-up voice system to enter the waiting-to-wake-up state again.

[0041] For example, if the actual voice command is not received within 10s, 15s, or 20s, the wake-up voice system is controlled to enter the waiting-to-wake-up state again. That is to say, if the actual voice command is not received within the preset time period, it will no longer wait for reception, but enter the waiting-to-wake-up state again.

[0042] Furthermore, the method further includes: if the actual voice instruction is received within the preset time period, the microphone is controlled to be turned off and the speaker is controlled to be turned on, and if the actual voice instruction is an invalid voice instruction, the speaker is controlled to play the voice that has not received a valid instruction, and waits for receiving a new actual voice instruction again. That is, if the actual voice instruction is received within the preset time period, but the actual voice instruction is invalid, the speaker plays for prompting, and waits for receiving a new actual voice instruction. However, the waiting state will not be entered again, that is, in this case, it is assumed to have been awakened.

[0043] Optionally, the wake-up command is issued by the user, and the method further includes: obtaining the user's behavior habits, including the frequency of the user waking up the voice system within a predetermined period; and determining the preset time period according to the user's behavior habits. Specifically, based on the research on user behavior habits and the collected experimental data, as well as the comprehensive analysis of the duration of the command in the command entry, monitoring whether there is an instruction within the preset time period can prevent the user from waking up by mistake or preventing the voice system from being turned on after no instruction.

[0044] Optionally, the method further includes: while executing the actual voice command and controlling the speaker to play the execution result, determining whether the execution is completed and whether the speaker has finished broadcasting; if the execution is completed and the speaker has finished broadcasting, waiting to receive a new actual voice command again; if the execution is not completed, waiting until the execution is completed; if the execution is completed but the speaker has not finished broadcasting, waiting until the speaker has finished broadcasting. That is, each actual voice command is broadcasted after execution is completed, and completion of execution and broadcasting indicates the end.

[0045] Optionally, after waking up the voice system, controlling the microphone to be turned off and the speaker to be turned on includes: after waking up the voice system, controlling the microphone to be turned off, and controlling the speaker to be turned on within a preset time period after the microphone is turned off. For example, a specific time delay is designed, and after receiving a valid instruction in the vocabulary, the microphone is turned off within a few milliseconds, and then the speaker is turned on within a few milliseconds, and the microphone and the speaker are turned on and off alternately to ensure that the audio of the speaker is not captured by the microphone.

[0046] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for preventing mutual interference between a speaker and a microphone of the present application will be described in detail below in combination with specific embodiments.

[0047] This embodiment relates to a specific method for preventing a loudspeaker and a microphone from interfering with each other. Figure 3 As shown, including:

[0048] 1. Waiting state: In the waiting state, the speaker is turned off and the microphone is in standby state;

[0049] 2. Wake-up phase: The user wakes up the voice system by inputting a specified wake-up command, and the voice control system program is started. After the voice system is started, the microphone is turned off, the speaker is turned on, and the response voice is broadcast. After completion, it enters the waiting for receiving commands phase;

[0050] 3. Waiting for command reception stage: the speaker is turned off, the microphone is turned on, and the device waits for actual voice commands (commands that actually control the device actions, such as turning on and off the air conditioner). It is determined whether there is an actual voice command within 10 seconds. If so, it enters the command judgment stage. If not, it returns to the waiting state and waits for wake-up.

[0051] 4. Command judgment stage: After the actual voice command is generated within 10 seconds, the microphone is turned off and the speaker is turned on to determine whether the actual voice command is a valid voice command. If so, it proceeds to the command execution stage. If not, the speaker replies to the user "no valid command received" and returns to the state of waiting to receive commands;

[0052] 5. Command execution stage: If it is a valid voice command, after executing the user's instruction, the speaker replies to the user and determines whether the execution and reply are completed. If so, it proceeds to the waiting command stage. If not, it repeats this step until it enters the waiting command stage;

[0053] This solution turns the microphone and speaker on and off before and after receiving and responding to user commands, so that the two parts are shielded from each other and do not work at the same time, thereby avoiding mutual interference between the parts during operation and problems such as the microphone being unable to clearly receive user commands or receiving erroneous commands, making the user experience smoother and enhancing the user experience.
