Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, the following detailed description of the embodiments of the present application will be made with reference to the accompanying drawings.
Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated object, indicating that there may be three relationships, for example, a and/or B, which may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Before the embodiments of the present application are described in detail, an implementation environment of the embodiments of the present application is described. The voice awakening method is applied to electronic equipment, the electronic equipment can be an intelligent sound box, an intelligent television, intelligent wearable equipment or a terminal and the like, and the terminal can be a mobile phone, a tablet computer or a computer and the like. Taking the electronic device as an example, the terminal may collect external voice data by using the method provided in the embodiment of the present application, identify whether the voice data includes a specific awakening word, and awaken the terminal according to the identification result.
In the related art, only a fixed voice wake-up scheme is generally adopted for voice wake-up in various complex scenes, such as performing voice recognition by a first processor with low power consumption, after the first processor recognizes that the acquired voice data has the appointed awakening words, the second processor with high power consumption is started to perform voice recognition, so that the power consumption of the terminal can be reduced to a certain extent, however, when the electronic device itself is in a high power consumption mode, it is not necessary to consider the limitation of power consumption, more resources should be utilized to improve the performance, because the power consumption caused by the voice wakeup process is very small and almost negligible compared to the power consumption of the electronic device itself, the user experience should be paid attention to in this scenario, if the first processor with low power consumption is first passed through, the wake-up throughput rate is affected due to the limitation of resources and power consumption.
In the embodiment of the present application, in order to solve the problems in the related art, a voice wake-up method capable of balancing power consumption and performance of an electronic device in a complex scene is provided, that is, a voice wake-up method in a multi-scene mixed mode is provided, which is described in detail in the embodiment of fig. 1 below.
Fig. 1 is a flowchart of a voice wake-up method provided in an embodiment of the present application, where the method is applied to an electronic device, and as shown in fig. 1, the method includes the following steps:
step 101: the method comprises the steps of detecting the device state of the electronic device, wherein a plurality of processors are configured in the electronic device, and the power consumption of the processors is different.
The device state of the electronic device may include a screen state and a sound output state, and may also include other device states, such as a memory state and an environmental noise state.
The screen state comprises a screen-off state and a screen-on state. The sound output state includes a state with sound output and a state without sound output. As an example, the sound output status is used to indicate whether a speaker of the electronic device has sound output, i.e. whether the electronic device is playing audio or video-audio.
Among other things, an electronic device may be configured with multiple processors that consume different amounts of power. For example, the electronic device may include two processors with different power consumptions, namely a first processor and a second processor, and the power consumption of the first processor is smaller than the power consumption of the second processor.
Alternatively, the electronic device is also configured with processors of three different power consumptions. For example, the electronic device is configured with a first processor and a second processor, and the second processor includes a first sub-processor and a second sub-processor, the power consumption of the first sub-processor and the power consumption of the second sub-processor are both greater than that of the first processor, and the power consumption of the first sub-processor is less than that of the second sub-processor.
Of course, the electronic device may also include four or more processors with different power consumptions, which is not limited in this embodiment of the application.
Step 102: according to the device state of the electronic device, the power consumption mode of the electronic device is determined, and a processor matched with the power consumption mode of the electronic device is determined from the plurality of processors.
In the embodiment of the application, the electronic device can be divided into multiple different power consumption modes according to the device state of the electronic device, and the different device states correspond to the different power consumption modes. The electronic device is provided with a plurality of processors, different power consumption modes are matched with different processors, and the processors matched with the power consumption modes are sampled in the corresponding power consumption modes to carry out voice wake-up processing.
As an example, if the power consumption mode of the electronic device is divided into two power consumption modes, and the plurality of processors configured in the electronic device include a first processor and a second processor, and the power consumption of the first processor is smaller than the power consumption of the second processor, the power consumption mode of the electronic device is determined according to the device state of the electronic device, and determining a processor from the plurality of processors that matches the power consumption mode of the electronic device may include the following two cases:
In the first case: if the screen state of the electronic equipment is a screen-off state and the sound output state of the electronic equipment is a state without sound output, determining that the power consumption mode of the electronic equipment is a first power consumption mode, and determining the first processor and the second processor as processors matched with the first power consumption mode.
Wherein the first power consumption mode is a low power consumption mode. When the screen state of the electronic device is the screen off state and the electronic device does not output sound, the power consumption mode of the electronic device at the time can be determined as the low power consumption mode, and the first processor and the second processor are determined as processors matched with the low power consumption mode, so that voice recognition is performed through the first processor first, and then voice recognition is performed through the second processor.
As one example, the first processor is a low power processor and the second processor is a high power processor that consumes more power than the first processor. Illustratively, the first Processor is a DSP (Digital Signal Processor), a high-fidelity (high fidelity) chip, a ceva (think) chip, or the like. The second processor may be an ARM (Advanced RISC Machine), an ADSP (Analog Device Instrument DSP, a digital signal processing chip manufactured by american Analog devices corporation), a CM4(Cortex-M4, a processor), or the like.
As an example, the first processor performs voice recognition on the monitored voice data by using a first voice wakeup algorithm to recognize whether a specified wakeup word exists in the voice data; and the second processor performs voice recognition on the monitored voice data by adopting a second voice awakening algorithm so as to recognize whether the designated awakening words exist in the voice data. Moreover, the speech recognition accuracy of the first voice wake-up algorithm is less than the second voice wake-up algorithm.
In the second case: and if the screen state of the electronic equipment is a bright screen state and/or the sound output state of the electronic equipment is a sound output state, determining that the power consumption mode of the electronic equipment is a second power consumption mode, and determining the second processor as a processor matched with the second power consumption mode.
Wherein the power consumption of the second power consumption mode is greater than the power consumption of the first power consumption mode. For example, the first power consumption mode is a low power consumption mode, and the second power consumption mode is a high power consumption mode.
When the screen state of the electronic device is a bright screen state or the electronic device has voice output, the power consumption mode of the electronic device at the moment can be determined as a high power consumption mode, and the second processor is determined as a processor matched with the high power consumption mode, so that voice recognition is directly performed through the high power consumption second processor without passing through the first processor, and the device performance and the awakening passing rate are improved.
In the embodiment of the application, when the electronic device is in the low power consumption mode, the voice monitoring and recognition can be performed by adopting a low power consumption voice awakening scheme matched with the low power consumption mode. If the electronic equipment is switched from the low-power-consumption mode to the high-power-consumption mode, the low-power-consumption voice awakening scheme can be switched to a high-power-consumption voice awakening scheme matched with the high-power-consumption mode for voice monitoring and recognition. If the electronic equipment is switched from the high-power-consumption mode to the low-power-consumption mode, the high-power-consumption voice awakening scheme can be switched to be in voice monitoring and recognition with the low-power-consumption voice awakening scheme. That is, along with the switching of the power consumption mode of the electronic device, the appropriate voice awakening scheme can be switched therewith, so that the electronic device can cope with complex use scenes, and the switching of various voice awakening schemes ensures that the performance of the device is guaranteed and better awakening experience is brought on the premise that the power consumption is acceptable.
As another example, it is also possible to divide the power consumption mode of the electronic device into three power consumption modes, configure three processors having different power consumption in the electronic device, and then determine a processor matching each power consumption mode from among the three processors, respectively.
In one possible implementation manner, the second power consumption mode may include a breaking (barkeln) mode and a high power consumption mode, power consumption of the breaking mode and the high power consumption mode is greater than that of the first power consumption mode, the second processor includes a first sub-processor and a second sub-processor, power consumption of the first sub-processor and power consumption of the second sub-processor are greater than that of the first processor, and power consumption of the first sub-processor is less than that of the second sub-processor, then the power consumption mode of the electronic device is determined according to the device state of the electronic device, and determining, from the plurality of processors, a processor that matches the power consumption mode of the electronic device may include the following three cases:
in the first case: if the screen state of the electronic equipment is a screen-off state and the sound output state of the electronic equipment is a state without sound output, determining that the power consumption mode of the electronic equipment is a first power consumption mode, and determining the first processor and the first sub-processor as processors matched with the first power consumption mode.
Wherein the first power consumption mode is a low power consumption mode. When the screen state of the electronic device is the screen off state and the electronic device does not output sound, the power consumption mode of the electronic device at the moment can be determined as the low power consumption mode, and the first processor and the first sub-processor are determined as the processors matched with the low power consumption mode, so that voice recognition is performed through the first processor first, and then voice recognition is performed through the first sub-processor.
As an example, the first processor performs voice recognition on the monitored voice data by using a first voice wakeup algorithm to recognize whether a specified wakeup word exists in the voice data; the first sub-processor performs voice recognition on the monitored voice data by adopting a second voice wake-up algorithm so as to recognize whether the designated wake-up words exist in the voice data. Moreover, the speech recognition accuracy of the first voice wake-up algorithm is less than that of the second voice wake-up algorithm.
In the second case: if the screen state of the electronic equipment is a screen-on state or a screen-off state, and the sound output state of the electronic equipment is a sound output state, determining that the power consumption mode of the electronic equipment is an interrupt mode, and determining the first sub-processor and the second sub-processor as processors matched with the interrupt mode.
Since the power consumption of each of the first and second sub-processors is greater than that of the first processor and the power consumption of the first sub-processor is less than that of the second sub-processor, the first processor may be referred to as a low power consumption processor, the first sub-processor as a sub-power consumption processor, and the second sub-processor as a high power consumption processor.
When the sound output state of the electronic device is a sound output state, it indicates that the electronic device is playing audio, and at this time, the electronic device can monitor not only the wake-up voice of the user, but also the sound emitted by the electronic device itself, and in this case, the power consumption mode in which the electronic device is located can be determined as an interrupt mode. When the electronic equipment is in the interrupt mode, the first sub-processor and the second sub-processor can be determined as processors matched with the interrupt mode, so that voice recognition is carried out through the first sub-processor firstly, and then voice recognition is carried out through the second sub-processor.
As an example, the first sub-processor performs voice recognition on the monitored voice data by using a third voice wake-up algorithm to recognize whether a designated wake-up word is included in the voice data; the second sub-processor performs voice recognition on the monitored voice data by adopting a second voice wake-up algorithm so as to recognize whether the voice data comprises a designated wake-up word. Moreover, the third voice wake-up algorithm has a voice recognition accuracy less than the second voice wake-up algorithm.
In a third case: and if the screen state of the electronic equipment is a bright screen state and the sound output state of the electronic equipment is a state without sound output, determining that the power consumption mode of the electronic equipment is a high power consumption mode, and determining the second sub-processor as a processor matched with the high power consumption mode.
Wherein the second sub-processor is a high power processor. When the electronic equipment is in a bright screen state and no sound is output, the power consumption mode of the electronic equipment at the moment can be determined as a high power consumption mode, the second sub-processor is determined as a processor matched with the high power consumption mode, so that voice recognition is directly carried out on the second sub-processor with high power consumption instead of the first processor or the first sub-processor, and the equipment performance and the wake-up passing rate are improved.
In the embodiment of the application, when the electronic device is in the low power consumption mode, the voice monitoring and the recognition can be performed by adopting a low power consumption voice awakening scheme matched with the low power consumption mode. If the electronic equipment is switched from the low-power-consumption mode to the interrupt mode, the low-power-consumption voice wake-up scheme can be switched to a second high-power-consumption voice wake-up scheme matched with the interrupt mode for voice monitoring and recognition. If the electronic equipment is switched from the interrupt mode to the high power consumption mode, the secondary high power consumption voice awakening scheme can be switched to be in voice monitoring and recognition with the high power consumption voice awakening scheme. That is, when the electronic device switches between the low power consumption mode, the interrupt mode and the high power consumption mode, the electronic device can switch the matched voice awakening scheme accordingly, so that the electronic device can deal with a complex use scene, and the switching of various voice awakening schemes ensures that the device performance is guaranteed and better voice awakening experience is brought on the premise that the power consumption is acceptable.
Step 103: and performing voice recognition on the monitored voice data through a processor matched with the power consumption mode of the electronic equipment, and performing voice awakening on the electronic equipment according to a voice recognition result.
As an example, if the power consumption modes of the electronic device are divided into two power consumption modes, and the multiple processors configured in the electronic device include a first processor and a second processor, where the power consumption of the first processor is less than the power consumption of the second processor, performing voice recognition on the monitored voice data by using a processor matched with the power consumption mode of the electronic device, and performing voice wake-up on the electronic device according to a voice recognition result may include the following two cases:
in the first case: if the power consumption mode of the electronic equipment is a first power consumption mode, voice monitoring is carried out through the first processor, and if voice data are monitored, voice recognition is carried out on the monitored voice data through a first voice awakening algorithm; and if the voice data is recognized to comprise the appointed awakening word through the first processor, performing voice recognition on the monitored voice data through the second processor by adopting a second voice awakening algorithm.
Furthermore, after the second processor performs voice recognition on the monitored voice data by adopting a second voice wake-up algorithm, if the voice data is recognized to include a designated wake-up word by the second processor, the electronic device can be directly triggered to wake up, or voiceprint recognition can be performed on the voice data by the second processor, and if the recognized voiceprint features are matched with the stored voiceprint features, the electronic device is triggered to wake up.
In the second case: and if the power consumption mode of the electronic equipment is the second power consumption mode, performing voice monitoring through the second processor, and if voice data is monitored, performing voice recognition on the monitored voice data by adopting a second voice awakening algorithm.
Further, after the second voice wake-up algorithm is adopted to perform voice recognition on the monitored voice data, if the voice data is recognized to include the designated wake-up word through the second processor, the electronic device can be directly triggered to wake up, or voiceprint recognition can be performed on the voice data through the second processor, and if the recognized voiceprint features are matched with the stored voiceprint features, the electronic device is triggered to wake up.
As another example, it is also possible to divide the power consumption mode of the electronic device into three power consumption modes, configure three processors having different power consumption in the electronic device, and then determine a processor matching each power consumption mode from among the three processors, respectively.
In a possible implementation manner, if the second power consumption mode includes an interrupt mode and a high power consumption mode, and the second processor includes the first sub-processor and the second sub-processor, performing voice recognition on the monitored voice data by using the processor matched with the power consumption mode where the electronic device is located, and performing voice wake-up on the electronic device according to a voice recognition result may include the following three cases:
In the first case: if the power consumption mode of the electronic equipment is a first power consumption mode, performing voice monitoring through a first processor, and if voice data is monitored, performing voice recognition on the monitored voice data by adopting a first voice awakening algorithm; and if the voice data recognized by the first processor comprises the appointed awakening word, performing voice recognition on the monitored voice data by adopting a second voice awakening algorithm through the second sub-processor.
Further, after the second sub-processor performs voice recognition on the monitored voice data by adopting a second voice wake-up algorithm, if the voice data is recognized to include the designated wake-up word by the second sub-processor, the electronic device can be directly triggered to wake up, or voiceprint recognition can be performed on the voice data by the second sub-processor, and if the recognized voiceprint features are matched with the stored voiceprint features, the electronic device is triggered to wake up.
In the second case: if the power consumption mode of the electronic equipment is an interruption mode, voice monitoring is carried out through the first sub-processor, if voice data are monitored, echo cancellation is carried out on the monitored voice data, and voice recognition is carried out on the voice data after the echo cancellation by adopting a third voice awakening algorithm; and if the voice data is recognized to comprise the appointed awakening word, performing voice recognition on the monitored voice data by adopting a second voice awakening algorithm through a second sub-processor.
Because when the electronic equipment is in the interruption mode, the electronic equipment also outputs sound, and when the electronic equipment monitors the sound through the first sub-processor, the electronic equipment not only can monitor the voice data of a user, but also can monitor the sound data sent by the electronic equipment, so that in order to improve the accuracy of voice recognition, echo cancellation can be firstly carried out on the monitored voice data so as to eliminate the sound sent by the electronic equipment.
In a third case: if the power consumption mode of the electronic equipment is a high power consumption mode, voice monitoring is carried out through the second sub-processor, and if voice data are monitored, voice recognition is carried out on the monitored voice data through a second voice awakening algorithm.
Further, after the third voice wake-up algorithm is adopted to perform voice recognition on the monitored voice data, if the voice data is recognized to include the designated wake-up word, the electronic device can be directly triggered to wake up, or voiceprint recognition can be performed on the voice data through the second sub-processor, and if the recognized voiceprint features are matched with the stored voiceprint features, the electronic device is triggered to wake up.
It should be noted that, in the embodiment of the present application, the manner of triggering to wake up the electronic device includes at least one of triggering the electronic device to turn on a screen, triggering the electronic device to turn on the screen and unlock the electronic device, triggering the electronic device to unlock the electronic device, finding the electronic device, and waking up a voice assistant of the electronic device.
As an example, if the screen state of the electronic device is an off-screen state, the manner of triggering the wake-up of the electronic device includes: triggering the electronic equipment to light the screen, triggering the electronic equipment to light the screen and unlock, searching the electronic equipment, and waking up at least one of the voice assistants of the electronic equipment. If the screen state of the electronic device is a bright screen state, the manner of triggering and awakening the electronic device comprises the following steps: triggering at least one of unlocking the electronic device, finding the electronic device, and waking up a voice assistant of the electronic device.
In the embodiment of the application, the equipment state of the electronic equipment is detected firstly, then the power consumption mode of the electronic equipment is determined according to the equipment state of the electronic equipment, the processor matched with the power consumption mode of the electronic equipment is used for carrying out voice recognition on the monitored voice data, and the electronic equipment is subjected to voice awakening according to the voice recognition result, so that the aim of different power consumption modes is fulfilled, the processors with different power consumption are adopted for carrying out voice awakening recognition and detection, so that the actual use scene of the electronic equipment can be combined, the equipment performance is ensured on the premise that the power consumption is acceptable by switching of multiple voice awakening modes, the power consumption and the performance of the equipment are balanced, and the influence on the voice awakening passing rate is avoided. In addition, the embodiment of the application can automatically identify the mode of the equipment, and balance between power consumption and performance is balanced by combining the characteristics of the equipment. Moreover, the advantages and disadvantages of the low-power-consumption processor and the high-power-consumption processor can be found accurately, a mixed-mode voice awakening scheme is provided by combining the scene characteristics of the equipment, and the problem that the performance of the equipment is limited and the voice awakening passing rate is influenced due to the fixed voice awakening scheme adopted in the related technology is solved.
A voice wake-up method of dividing the power consumption mode of the electronic device into two power consumption modes will be exemplified next. Fig. 2 is a flowchart of another voice wake-up method provided in an embodiment of the present application, where the method is applied to a voice wake-up apparatus, and as shown in fig. 2, the method includes the following steps:
step 201: a device state of an electronic device is detected, the device state including a screen state and a sound output state, the electronic device having a low power consumption processor and a high power consumption processor disposed therein.
Step 202: and if the screen state of the electronic equipment is the screen off state and the sound output state of the electronic equipment is the state without sound output, determining that the electronic equipment is in the low power consumption mode.
Step 203: if the electronic equipment is in the low-power-consumption mode, firstly carrying out voice monitoring through the low-power-consumption processor, carrying out voice recognition on the monitored voice data, and then carrying out voice recognition on the voice data through the high-power-consumption processor.
As an example, voice monitoring is performed through a low-power processor, and if voice data is monitored, voice recognition is performed on the monitored voice data by using a first voice wake-up algorithm; and if the voice data is recognized to comprise the appointed awakening word, performing voice recognition on the monitored voice data by adopting a second voice awakening algorithm through the high-power-consumption processor. And the voice recognition accuracy of the second voice awakening algorithm is greater than that of the first voice awakening algorithm.
Step 204: if the voice data is recognized to comprise the appointed awakening word through the high-power-consumption processor, the high-power-consumption processor continues to perform voiceprint recognition on the voice data, and if the voiceprint recognition is passed, the electronic equipment is triggered to be awakened.
Step 205: and if the screen state of the electronic equipment is a bright screen state and/or the sound output state of the electronic equipment is a sound output state, determining that the electronic equipment is in a high power consumption mode.
Step 206: and if the electronic equipment is in the high power consumption mode, directly performing voice monitoring through the high power consumption processor, and performing voice recognition on the monitored voice data.
As an example, if the electronic device is in the high power consumption mode, performing voice monitoring through the high power consumption processor, and if voice data is monitored, performing voice recognition on the monitored voice data by using a second voice wake-up algorithm.
Step 207: and if the voice data is recognized to comprise the appointed awakening word through the high-power-consumption processor, performing voiceprint recognition on the voice data through the high-power-consumption processor, and if the voiceprint recognition is passed, triggering and awakening the electronic equipment.
In the embodiment of the application, the power consumption modes of the electronic equipment can be divided into the low power consumption mode and the high power consumption mode, when the electronic equipment is switched between the low power consumption mode and the high power consumption mode, the electronic equipment can switch the matched voice awakening scheme accordingly, so that the electronic equipment can cope with complex use scenes, the equipment performance is guaranteed on the premise that the power consumption is acceptable through switching of various voice awakening schemes, and better voice awakening experience is brought.
As an example, a schematic diagram of the voice wake-up scheme that the electronic device switches to match when the electronic device switches between the low power consumption mode and the high power consumption mode may be as shown in fig. 3.
A voice wake-up method of dividing the power consumption mode of the electronic device into three power consumption modes will be exemplified next. Fig. 4 is a flowchart of another voice wake-up method provided in an embodiment of the present application, where the method is applied to a voice wake-up apparatus, and as shown in fig. 4, the method includes the following steps:
