All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of an embodiment of a wake-up recognition processing method according to the invention is shown, wherein a wake-up recognition processing method is used for a bluetooth peripheral.
As shown in fig. 1, in step 101, in response to the bluetooth peripheral being awakened, establishing a bluetooth transmission channel with the master device, wherein the master device has a voice recognition capability and the bluetooth peripheral does not have the voice recognition capability;
in step 102, first audio data received after waking up is transmitted to the master device in real time via the bluetooth transmission channel.
In this embodiment, for step 101, the wakeup identification processing device responds to that the bluetooth peripheral is waken up, and establishes a bluetooth transmission channel with the host device, where the host device has a voice recognition capability, and the bluetooth peripheral does not have a voice recognition capability, for example, the bluetooth peripheral is a bluetooth headset, the host device is a smart phone, and when the bluetooth headset is turned on, the collected audio is analyzed in real time until a wakeup word of a user is detected, and then the bluetooth transmission channel between the bluetooth headset and the smart phone is established;
for step 102, the first audio data received after waking up is transmitted to the main device in real time through the bluetooth transmission channel, for example, the bluetooth external device is a bluetooth headset, the main device is a smart phone, and after the bluetooth transmission channel is established, the bluetooth headset continuously transmits the audio received after waking up to the mobile phone.
In the scheme of the embodiment, the Oneshot function is completed through the matching of the Bluetooth peripheral and the voice processing service in the main equipment.
Please refer to fig. 2, which shows a flowchart of another wake-up identification processing method according to an embodiment of the present invention, and the flowchart mainly refers to a flowchart of a step further defined by "establishing a bluetooth transmission channel with the master device in response to the bluetooth peripheral being woken up" in step 101 "in fig. 1. Wherein, the bluetooth peripheral equipment possesses the buffer memory ability.
As shown in fig. 2, in step 201, continuously caching the second audio data with a fixed duration, and analyzing whether the second audio data contains a wakeup word in real time;
in step 202, if the second audio data includes a wakeup word, a bluetooth transmission channel with the master device is established.
In this embodiment, for step 201, after the Oneshot function is turned on, the wakeup identification processing device continues to cache the second audio data with a fixed duration, and analyzes whether the second audio data contains a wakeup word in real time; then, in step 202, if the second audio data includes a wakeup word, a bluetooth transmission channel with the master device is established. For example, in a scenario where a user drives a car and goes out, the bluetooth peripheral device continues to cache an audio of a fixed duration until a wakeup word is detected, for example, one cached audio is: remove Beijing West station and use slightly. And the Bluetooth peripheral establishes a Bluetooth transmission channel with the main equipment after detecting the awakening word.
In the scheme of this embodiment, the second audio data with a fixed duration is cached continuously, so that the user instruction can be recognized normally even if the user instruction is in front of the wakeup word.
Please refer to fig. 3, which shows a flowchart of another wake-up identification processing method according to an embodiment of the present invention, and the flowchart mainly refers to a flowchart of steps further defined before step 202 "establishing a bluetooth transmission channel with the master device" in fig. 2.

For example, the bluetooth peripheral may close the bluetooth transmission channel before receiving no audio request from the host device, and may establish the bluetooth transmission channel with the host device only after receiving the audio request from the host device.
In the scheme of the embodiment, the Bluetooth transmission channel between the Bluetooth peripheral and the main equipment is established through the audio request of the main equipment, so that the power consumption of the Bluetooth peripheral after Oneshot is started can be reduced, the standby time is prolonged, and the identification accuracy is obviously improved.

Another example is: quickly available, slightly relaxed, to beijing west station. The small relaxation is a wake-up word, the cache audio is arranged before the small relaxation, and the audio received after wake-up is arranged after the small relaxation. The audio transmitted to the main device by the Bluetooth peripheral comprises cache audio and audio received after awakening.
In the scheme of this embodiment, the audio transmitted to the main device includes the buffered audio and the audio received after awakening, so that the awakening word and the user instruction do not have the sequence, and the voice interaction is more convenient and intelligent.

In the scheme of the embodiment, the audio data transmitted by the Bluetooth peripheral is received, and the voice recognition processing is carried out on the audio data, so that the Oneshot function can be realized by matching with the Bluetooth peripheral.
Please refer to fig. 5, which shows a flowchart of another wake-up recognition processing method according to an embodiment of the present invention, and the flowchart mainly refers to a flowchart of a step defined further by "receiving audio data transmitted by a bluetooth peripheral based on a bluetooth transmission channel established with the bluetooth peripheral" in step 401 of fig. 4.
As shown in fig. 5, in step 501, in response to receiving a wake-up command sent by the bluetooth peripheral, sending an audio request to the bluetooth peripheral;

And the accuracy rate of identification is obviously improved.
The following description is provided to enable those skilled in the art to better understand the present disclosure by describing some of the problems encountered by the inventors in implementing the present disclosure and by describing one particular embodiment of the finally identified solution.
The inventors discovered the defects of these similar techniques in the process of implementing the present invention:
the Bluetooth peripheral collects audio in real time and transmits the audio to the master device through wireless signals, so that the Bluetooth peripheral consumes serious power and cannot stand by for a long time.
The Oneshot function is specifically realized at the main equipment end, so that audio needs to be transmitted in real time through wireless signals, and the power consumption is serious.
The inventors have found in the course of carrying out the invention why the reason is not easily imaginable:
oneshot functions are typically implemented independently on the bluetooth peripheral. The Oneshot function relies on waking up, recognition and semantic understanding. Higher hardware capabilities are required, including CPU processing power, memory size. This results in very high cost and power consumption of the bluetooth peripheral.
Since the present solution requires coordination with the voice processing services of the master device. Voice technology capabilities are required to reach deep into the software development phase of bluetooth peripherals. It is desirable that the practitioner be able to master both the bluetooth peripheral and the voice technology development capabilities.
The technical problem existing in the prior art is solved through the following scheme:
the Bluetooth peripheral is internally provided with a wakeup module for analyzing the acquired audio in real time. Meanwhile, after the peripheral starts the Oneshot function, the audio of fixed time can be cached all the time. And when the awakening event is triggered, the Bluetooth wireless channel is started, and the cached audio and the subsequent real-time audio are transmitted to the main equipment. And the Oneshot function is completed by matching with the voice processing service in the main equipment.
Because the wireless transmission of the audio is started only after a specific awakening event, the power consumption of the Bluetooth peripheral can be obviously reduced, and the Bluetooth peripheral can operate with low power consumption for a long time.
The invention has the technical innovation points that:
the process is described in detail:
the Bluetooth peripheral analyzes the real-time audio, waits for the occurrence of a wake-up event, and synchronously caches the audio of a fixed duration.
And after the wake-up event occurs, the main equipment is informed, the main equipment prepares voice service and requests the peripheral equipment to transmit audio.
The peripheral transmits the cache audio and the subsequent real-time audio to the main device through a wireless Bluetooth channel.
And the voice service in the main equipment processes the acquired audio and is matched with the peripheral equipment to realize the Oneshot function.
In the process of implementing the present application, the inventors have also tried the following schemes:
the difference with the official version is that the Bluetooth peripheral does not increase the audio buffer. And a wakeup function is added on the Bluetooth peripheral, and after a wakeup word is detected, the awakened audio is transmitted through a Bluetooth wireless signal trial. And the Oneshot function is realized by matching with the main equipment. The scheme does not need to transmit audio to the main equipment end in real time to realize complete functions, so the aim of saving power is also fulfilled.
The advantages are that:
the scheme is mature, and the Bluetooth peripheral does not need to be modified greatly.
The disadvantages are as follows:
and the buffer is lacked, so that the front part of audio is lost after transmission, and the effect is not ideal.
Referring to fig. 7, a block diagram of a wake-up recognition processing apparatus according to an embodiment of the invention is shown.
As shown in fig. 7, the wake-up recognition processing apparatus 700 includes: a wake-up module 710 and a transmission module 720.
The wakeup module 710 is configured to, in response to the bluetooth peripheral being woken up, establish a bluetooth transmission channel with the host device, where the host device has a voice recognition capability and the bluetooth peripheral does not have the voice recognition capability; a transmission module 720, configured to transmit the first audio data received after waking up to the master device in real time via the bluetooth transmission channel.
As shown in fig. 8, another processing apparatus 800 for wake up identification is shown, comprising: a receiving module 810 and an identification processing module 820.
The receiving module 810 is configured to receive audio data transmitted by a bluetooth peripheral based on a bluetooth transmission channel established with the bluetooth peripheral;
