Description
Technical Field

Background
With the advent of voice human-computer interaction interfaces, more and more products are required to interact with intelligent voice. The intelligent voice interaction products in the current market are all products based on wifi, but wifi power consumption is large, and portability is poor. Moreover, the development of smart phones has formed a portable computing center. Therefore, an intelligent voice interaction product which relies on the Bluetooth technology to realize portability can be an important development trend. And the traditional mode of transmitting voice between the Bluetooth and the mobile phone is the classic Bluetooth mode, so that the problem of frequent switching of the classic Bluetooth mode of the mobile phone can be caused, and the experience is poor.
The Audio transmission of the classic bluetooth is realized by two bluetooth profiles, HFP (Hands-free Profile) and A2DP (Advanced Audio Distribution Profile, bluetooth Audio transmission model protocol). HFP is used in a telephone call scenario featuring real-time two-way voice communication, while A2DP is used in a listening stereo music scenario featuring one-way audio push. The two bluetooth audio communications occupy the classic bluetooth channel and in the current implementation are switched from one to the other depending on the scene. Therefore, the current voice requirement of the bluetooth audio product is to perform voice data acquisition by switching the mode from the A2DP scene listening to songs to the HFP scene, which has two problems, 1, establishing a new system link requires time, and needs to wait for approximately 2 seconds, which is very poor in experience. 2, the voice data needs to be collected and transmitted immediately after a collection instruction is sent, and the former data is lost due to the old mode switching mode. Since the access mode of the smart voice of the old handset is accessed by HFP of the classic bluetooth, the A2DP mode is used when music is played. When a smart voice input requirement is initiated during music playing, the mode needs to be switched from the A2DP mode to the HFP mode, and the time for the mobile phone and the bluetooth terminal to establish HFP switching needs to be close to 2 seconds. And old implementation mode can't gather pronunciation and upload data when establishing the bluetooth connection, waits for 2 seconds the link to be established, and this 2 seconds's pronunciation data is not gathered, so produce the data loss, and experience the not good condition.
A new speech processing technique is needed to address the deficiencies of the prior art.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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.
An embodiment of the present invention provides an intelligent voice system, and referring to fig. 1, which is a structural block diagram of the intelligent voice system provided in the embodiment of the present invention, and the intelligent voice system includes a bluetooth terminal 1 and an intelligent device 2; the Bluetooth terminal 1 comprises a microphone array 101, a voice preprocessing device 103, a first transmission device 102 and a playback device 104; the intelligent device 2 comprises a second transmission device 201 and an intelligent processor 202; the first transmission device 102 comprises a first BLE communications device 2021 and a first A2DP communications device 1022, and the second transmission device 201 comprises a second BLE communications device 2011 and a second A2DP communications device 2012; the voice preprocessing device 103 is connected to the microphone array 101, and is configured to preprocess a first audio signal acquired by the microphone array 101 and send the preprocessed first audio signal to the second BLE communication device 2011 through the first BLE communication device 1021; the playback device 104 is connected to the first A2DP communication device 1022 for receiving a second audio signal transmitted by the second A2DP communication device 2012 through the first A2DP communication device 1022. While the first A2DP communication device 1022 is in second audio signal transmission with the second A2DP communication device 2012, the first BLE communication device 1021 is in first audio signal transmission with the second BLE communication device 2011.
The intelligent device is an intelligent mobile phone, a tablet personal computer, an intelligent television or an intelligent set top box. The following description will be made in detail by taking a mobile phone as an example.
Specifically, when the mobile phone terminal is connected to a bluetooth terminal (e.g., a bluetooth sound box) in an A2DP mode and plays a song, the mobile phone terminal performs a communication connection with a first A2DP communication device of the bluetooth terminal through a second A2DP communication device to transmit the song (i.e., the second audio signal) of the mobile phone terminal to the bluetooth terminal, and the song is played by a playback device of the bluetooth terminal, where the connection established between the two devices is an A2DP protocol. When the Bluetooth terminal receives a voice control request, namely a first audio signal, the first audio signal is not required to be sent to the mobile phone end through classical Bluetooth transmission at the moment, but data transmission is carried out through a BLE channel, and a first BLE communication device of the Bluetooth terminal is connected with a second BLE communication device of the mobile phone end after preprocessing the first audio signal and sends the first audio signal to the mobile phone end. Because the BLE Bluetooth mode does not conflict with the classic Bluetooth transmission, when the multi-array microphone receives the first audio signal, the first audio signal can be directly transmitted through the BLE channel without waiting for the switching of the classic mode Bluetooth transmission protocol.
The embodiment of the present invention is specifically described below with a specific example, when the mobile phone end is connected to the bluetooth terminal and the bluetooth terminal plays a song in the mobile phone, the connection is established between the mobile phone end and the bluetooth terminal through the A2DP transmission device, the second audio data is transmitted, the audio data is unidirectionally transmitted from the mobile phone end to the bluetooth terminal, and the playback device of the bluetooth terminal decodes the audio data and plays the audio data. At this time, when the user sends a voice instruction to the bluetooth terminal: the voice command is a first audio signal described in the embodiment of the present invention, and at this time, when the multi-array microphone of the bluetooth terminal receives the voice command, since the voice preprocessing device of the bluetooth terminal cannot recognize the voice command, the voice command needs to be transmitted to the mobile phone end or the voice cloud server for recognition processing, so that the bluetooth terminal immediately sends the voice command to the second BLE communication device of the mobile phone end through the first BLE communication device of the bluetooth terminal after performing voice preprocessing through a BLE protocol established between the mobile phone end and the bluetooth terminal, after the intelligent processor of the mobile phone end processes the first audio signal, the instruction is fed back to the bluetooth terminal, and the bluetooth terminal receives the instruction to start playing the song of dunlijun. During the whole BLE transmission and feedback command, the A2DP protocol connection is still established and not terminated, that is, the song is still playing. It will be appreciated that if the voice command is a relatively simple command, for example: playing, stopping, increasing the volume, reducing the volume, answering the call, hanging up the call and the like, and directly carrying out identification processing by the Bluetooth terminal. Only voice commands are complex, such as: please help me find where the nearest gasoline station is? Today is the weather? And when the instruction is received, the instruction needs to be transmitted to a mobile phone end or a voice cloud server for processing.
The invention provides another embodiment, when the intelligent processor at the mobile phone end cannot meet the requirement of voice recognition processing, the voice recognition function of the voice cloud server 3 needs to be further used, the embodiment of the invention further comprises the voice cloud server on the basis of the system, and the voice cloud server is in remote communication with the intelligent equipment and acquires the first audio signal sent by the intelligent equipment for processing the first audio signal. And data transmission is carried out between the voice cloud server and the intelligent equipment through a wireless network. According to the size of the voice calculation amount, generally, simple voice processing can be completed at the mobile phone end intelligent processor, the voice recognition function application of most front-end equipment can be met, and the voice processing can be completed by using the voice cloud server under the condition that the mobile phone end intelligent processor cannot meet the operation or processing.
According to the embodiment of the invention, the microphone array is an analog microphone array or a digital microphone array, and usually the microphone array comprises 1-8 microphones, which is a standard far-field voice acquisition configuration, and usually 2 microphones are used to form the microphone array, and only 1 microphone may be used in some quiet situations.
In another embodiment of the present invention, the voice pre-processing apparatus further comprises:
a wake-up device 1031 connected to the microphone array for waking up the voice preprocessing device and the first transmission device;
a noise reduction device 1032 connected between the microphone array and the first transmission device, for performing noise reduction processing on the acquired audio signal;
a beam forming device 1033 connected with the microphone array for enhancing the voice collection in a specific direction;
an echo cancellation device 1034 connected between the noise reduction device and the first transmission device, and configured to perform echo cancellation processing on the acquired audio signal.
In order to provide further advanced speech processing, as shown in fig. 2, the speech preprocessing unit 103 further comprises a wake-up unit 1031 connected to the microphone array 101 for waking up the speech preprocessing unit 103 and the first transmission unit 102. The voice preprocessing device 103 further includes a noise reduction device 1032 connected between the microphone array 101 and the first transmission device 102 for performing noise reduction processing on the acquired audio signal. The voice preprocessing device 103 further includes a beam forming device 1033 connected to the microphone array 101 for enhancing the voice acquisition in a specific direction by the microphone array 101. The voice pre-processing device 103 further comprises an echo cancellation device 1034 connected between the noise reduction device 1032 and the encoding device 1035, and configured to perform echo cancellation processing on the acquired first audio signal. The awakening device is used for voice signals collected by a microphone array, determining an algorithm for starting voice awakening according to energy or characteristics (zero crossing point detection, spectrum analysis and the like) of human voice, comparing input voice with a maximum likelihood algorithm of a large batch of training sequences in advance, determining whether the voice input is an awakening word, and starting subsequent processing if the voice input is the awakening word. The beam forming device 1033 is used for determining the input direction of the sound signal relative to the microphone array according to the time delay and phase difference of the voice data of each microphone when the multi-microphone voice is input, and determining the parameter of the noise reduction device according to the information. The noise reducer 1032 strengthens or weakens signals in different directions according to noise reduction parameters of a beam forming algorithm or a preset noise reduction directional diagram curve, and highlights the signal strength in the latest direction. Meanwhile, according to the frequency spectrum difference of human voice and environmental sound (periodic noise, music) and the difference of time domain correlation, the signal is processed in frequency domain or time domain, and the human voice is extracted and enhanced from background sound or noise. When the playback module exists, the echo cancellation device 1034 adds the predetermined or predicted transfer function to the decoded data, and cancels the reflected part of the sound emitted from the loudspeaker in the data collected by the microphone, so as to obtain the clean voice without echo.
It can be understood that, when the voice pre-processing device has insufficient computing power and is not suitable for performing the above processing, the wake-up device, the noise reduction device, and the beam forming device may be disposed in the smart device 2 for processing, so as to reduce the computation of the voice pre-processing device 103. The smart device further includes: the awakening device is used for awakening the voice preprocessing device and the first transmission device; the noise reduction device is used for carrying out noise reduction processing on the acquired audio signal; and the beam forming device is used for enhancing the voice acquisition in a specific direction. The above apparatus may be provided in an intelligent processor of an intelligent device.
According to another aspect of the embodiments of the present invention, an embodiment of the present invention further provides a voice processing method for an intelligent voice system, which directly implements a function of returning voice without performing bluetooth service switching on an original bluetooth audio path of A2DP, and implements non-delay voice acquisition.
The embodiment of the present invention is implemented as follows, and a speech processing method in an intelligent speech system, as shown in fig. 3, includes the following steps: (S101) a microphone array of the Bluetooth terminal acquires a first audio signal and sends the first audio signal to a voice preprocessing device; (S102) the voice preprocessing device transmits the first audio signal to intelligent equipment through a BLE transmission protocol after preprocessing; (S103) the intelligent equipment processes the first audio signal and then returns a control signal to the voice preprocessing device.
The first audio signal is transmitted to the intelligent device through a BLE transmission protocol, and the second audio signal is transmitted to the Bluetooth terminal through an A2DP protocol by the intelligent device.
The following description will be made in detail by taking a mobile phone as an example.
Specifically, when the mobile phone terminal is connected to the bluetooth terminal in the A2DP mode and plays a song, the mobile phone terminal performs communication with the first A2DP communication device of the bluetooth terminal through the second A2DP communication device to transmit the song (i.e., the second audio signal) of the mobile phone terminal to the bluetooth terminal and play the song by the playback device of the bluetooth terminal, and at this time, the connection established between the two is the A2DP protocol. A microphone array of the Bluetooth terminal acquires a first audio signal and sends the first audio signal to a voice preprocessing device; the voice preprocessing device transmits the first audio signal to a mobile phone end through a BLE transmission protocol after preprocessing; and the mobile phone end intelligent processor identifies the first audio signal and then returns a control signal to the voice preprocessing device, and the voice preprocessing device acquires the returned control signal and then controls the Bluetooth terminal according to the first audio signal. When the Bluetooth terminal receives a voice control request, namely a first audio signal, the first audio signal is not required to be sent to the mobile phone end through classical Bluetooth transmission at the moment, but data transmission is carried out through a BLE channel, and a first BLE communication device of the Bluetooth terminal is connected with a second BLE communication device of the mobile phone end after preprocessing the first audio signal and sends the first audio signal to the mobile phone end. Because the BLE Bluetooth mode does not conflict with the classic Bluetooth transmission, when the multi-array microphone receives the first audio signal, the first audio signal can be directly transmitted through the BLE channel without waiting for the switching of the classic mode Bluetooth transmission protocol.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
