[0002] With the development of artificial intelligence and voice recognition technology, voice control has gradually become a new technical research direction for white appliance manufacturers. Voice modules have also become a new module demand by white appliance manufacturers after wireless modules such as WiFi. However, the voice modules produced must pass the test before they can be shipped.
[0003] Because the voice module only has a MIC input interface and a speaker output interface, during production testing, a MIC and a speaker are usually connected to the production test tool to manually verify whether the voice input and output links are normal, or specific voice information is output through the speaker and picked up by the MIC to determine whether the link is normal.
[0004] However, existing production testing solutions are inefficient and prone to mutual interference and misjudgment when multiple modules are tested simultaneously. Utility Model Content
[0005] The embodiments of the present application provide a voice function detection system and device to at least solve the problem that the production and testing solutions in the related art are inefficient and easily interfere with each other and cause misjudgment when multiple modules are tested simultaneously.

[0034] In a first aspect, the embodiments of the present application provide a voice function detection system. Figure 1 This is a structural block diagram of the voice function detection system provided by the embodiment of the present application. Figure 1 As shown, the system includes a voice module 100 and a filtering and rectifying circuit 200 .
[0035] The filtering and rectifying circuit 200 is electrically connected to the voice module 100 and is used to receive the voice signal transmitted by the voice module, filter and rectify the voice signal to obtain an input electrical signal, and transmit the input electrical signal to the voice module.
[0036] Optionally, a filtering and rectifying circuit converts the received voice information into an electrical signal and transmits it directly to the voice module, forming a complete test loop. This eliminates the need for connecting a microphone and speaker, and eliminates the need for manual judgment of the voice module's input and output functions, thus avoiding the problem of misjudgment caused by mutual influence when testing multiple modules.
[0037] In one example, the filtering and rectifying circuit includes a DC blocking circuit and a voltage divider circuit connected in series. The DC blocking circuit is used to filter the DC component in the voice signal, and the voltage divider circuit is used to reduce the amplitude of the voice signal.
[0038] Optionally, a DC blocking circuit is used to filter the DC component in the voice signal output by the power amplifier. The power amplifier can be an analog power amplifier or a digital power amplifier. The order of the DC blocking circuit and the voltage divider circuit can be adjusted according to actual needs.
[0039] In one example, the filtering and rectifying circuit further includes an RC rectifying circuit connected in series with the DC blocking circuit and the voltage divider circuit.
[0040] Optionally, the power amplifier may be an analog power amplifier or a digital power amplifier. Figure 2 This is a schematic diagram of the structure of a filter and rectifier circuit according to an exemplary embodiment. In a digital power amplifier, the filter and rectifier circuit also includes an RC rectifier circuit, which is used to rectify the voice signal output by the digital power amplifier. In an analog power amplifier, the RC rectifier circuit can be omitted. When the circuit includes a DC blocking circuit, an RC rectifier circuit, and a voltage divider circuit, the order of these three circuits can be adjusted according to actual application requirements.
[0041] In one example, the RC rectifier circuit is a first-order RC filter circuit or a second-order RC filter circuit. Optionally, a second-order RC filter circuit structure can more effectively filter high-frequency ripple than a first-order RC filter circuit structure, providing a more stable DC output. The choice of which structure to use depends on the specific application requirements and the required output waveform smoothness. The resistance and capacitance values in the circuit can be adjusted according to actual needs.
[0042] In one example, the voice module 100 includes a voice output interface and a voice input interface. Figure 3 FIG. 1 is a structural diagram of a voice function detection system according to an exemplary embodiment. Figure 3 As shown, the filter and rectifier circuit is electrically connected to the voice output interface to receive the voice signal transmitted by the voice output module. The filter and rectifier circuit is electrically connected to the voice input interface to transmit the input electrical signal to the voice module through the voice input interface.
[0043] The voice module 100 is used to receive an input electrical signal and determine whether the voice input and output functions of the voice module can operate normally according to the input electrical signal.
[0044] Optionally, a sound processing unit in the voice module is used to determine whether the input and output functions are normal. The sound processing unit includes an analog signal processing circuit, a digital signal processor (DSP), or a dedicated sound processing chip. The sound processing unit determines whether the input and output functions of the module are normal based on the received input electrical signal.
[0045] The following methods can be used to analyze whether the input and output functions of the voice module are normal: (1) Use speech recognition algorithms or feature extraction techniques to analyze the received voice signal. These algorithms can detect specific characteristics of the voice, such as spectrum, energy, duration of the voice segment, etc. (2) Evaluate the quality of the voice signal, including analyzing the clarity of the sound, noise level, and whether there is distortion to determine whether the voice output and input meet the expected quality standards. (3) Through voice matching and comparison, match or compare the received voice signal with the voice model stored in the internal or external database to determine whether the voice matches the expected voice command or pattern.
[0046] In one example, the system also includes a feedback module, which is used to provide feedback to the user via an indicator light. Optionally, the voice module includes an indicator light, which controls the indicator light to provide feedback to the user, indicating the voice module's functional judgment results. For example, if there is an abnormality in the output or output function, a red light can be controlled to illuminate to alert relevant personnel.
[0047] In one example, the system further includes a transmission module for transmitting the judgment result to the user. Optionally, when an output or output function has an abnormality, the abnormality information is sent to the device side or server side of the relevant personnel for the relevant personnel to handle according to the abnormality information.
[0048] In summary, the present application uses a device for automated production testing of electronic products, connects a filter rectifier circuit to the speaker output interface of the voice module, converts the originally output voice information into an electrical signal, and then directly inputs it into the microphone input interface of the voice module. The sound processing unit in the voice module judges whether there is a problem with the module's voice output and input link based on the input electrical signal. In this way, there is no need for an external microphone and speaker, and no manual participation, while avoiding mutual interference between modules when multiple modules are tested at the same time. The test efficiency and test accuracy of the voice module are improved.
[0049] In a second aspect, an embodiment of the present application provides a voice function detection device, which is applied to the voice function detection system of the first aspect, and is used to cooperate with a voice module. Figure 4 is a structural block diagram of a voice function detection device according to an embodiment of the present application, as shown in FIG. Figure 4 As shown, the device includes:
[0050] The circuit board 201 is provided with a first pin 2011 and a second pin 2012 .
[0051] The filtering and rectifying circuit 200 is electrically connected to the voice module 100 via a first pin and a second pin.
[0052] Optionally, the voice function detection device is only used in the testing phase after the voice module is produced and before it leaves the factory. The voice function detection device is usually fixed to the automated production and testing equipment. In the automated production process, no human intervention is required, and the production and testing of the voice module can be completed automatically.
[0053] In summary, the present application uses a device for automated production testing of electronic products, connects a filter rectifier circuit to the speaker output interface of the voice module, converts the originally output voice information into an electrical signal, and then directly inputs it into the microphone input interface of the voice module. The sound processing unit in the voice module judges whether there is a problem with the module's voice output and input link based on the input electrical signal. In this way, there is no need for an external microphone and speaker, and no manual participation, while avoiding mutual interference between modules when multiple modules are tested at the same time. The test efficiency and test accuracy of the voice module are improved.
[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
