Abstract
The utility model provides a Bluetooth device with voice wake-up. The Bluetooth device includes an audio capture unit (1), a Bluetooth communication unit (4), a voice wake-up processing unit (2) and a main control unit (3); an output end of the audio capture unit (1) is connected to an audio input end of the voice wake-up processing unit (2); an input end of the Bluetooth communication unit (4) is connected to an output end of the main control unit (3); an output end of the Bluetooth communication unit (4) is connected to an input end of the main control unit (3); and a control output end of the voice wake-up processing unit (2) is connected to a controlled input end of the main control unit (3). According to the utility model, simply through a specific voice command, a certain specific operation can be achieved, such as actions to answer or initiate phone voice recognition.
Description
Technical field
The utility model relates to a kind of blue-tooth device waking up with voice, belongs to voice awakening technology at the application apparatus in bluetooth field.
Background technology
Hands free applications framework agreement HFP based in Bluetooth Communication Technology, allows bluetooth equipment can control phone in this agreement, as answer, hang up, rejection, phonetic dialing etc., it has defined audio frequency net gate way (AG) and two roles of hands-free assembly (HF).AG is the gateway device of audio frequency input and output.Typical audio frequency net gate way mainly contains bluetooth cellular phone; HF refers to the equipment that can receive and dispatch audio frequency remote control AG, and typical hands-free assembly mainly contains bluetooth earphone and bluetooth vehicle-mounted hand free device.The combination that current Bluetooth technology and voice wake up is all to say that voice wake module is placed on AG, user sends phonetic order to HF, HF records and recording is carried out to compressed encoding processing, audio frequency after coding sends to AG by Bluetooth communication protocol and holds, at AG end to the audio frequency recovery of decoding, again the voice after recovering are sent into voice wake module and carry out identifying processing, then existing audio coding mode mostly is lossy compression method, after coding is decoded again, voice quality can change, and affects wake-up effect.
Utility model content
The purpose of this utility model is to improve a kind of mode that can wake up by voice and substitutes the button control mode of blue-tooth device in the past, only need by a specific phonetic order, can realize some concrete operations, such as realizing one, answer or start the actions such as mobile phone speech identification.
In order to realize above object, the utility model has adopted following technical scheme: a kind of blue-tooth device waking up with voice, comprise audio collection unit, bluetooth-communication unit, voice wake up process unit, main control unit, the output of audio collection unit is connected with the audio input end of voice wake up process unit, the output of bluetooth-communication unit input and main control unit is connected, the output of bluetooth-communication unit is connected with the input of main control unit, being connected by control input end of the control output end of voice wake up process unit and main control unit.
Preferably, this main control unit adopts the main control chip of the operation basic controlling logic of having the ability, and this main control chip is single-chip microcomputer, ARM chip or M0.
Preferably, this voice wake up process unit adopts the processed voice of having the ability to wake the processor of algorithm up, and this processor is M0 or DSP.
As shown from the above technical solution, audio collection unit in the utility model is for gathering extraneous sound, audio collection unit is processed the Speech input collecting in voice wake up process unit, if predefined specific sound instruction, a signal being waken up of voice wakeup unit output is to main control unit, main control unit is received after the wake-up signal of voice wake up process unit output, be converted into certain Bluetooth communication command to bluetooth-communication unit, thereby complete corresponding control.
Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail.
As shown in Figure 1, a kind of blue-tooth device waking up with voice, comprise main control unit 3, its Bluetooth communication input is connected with the output of bluetooth-communication unit 4, its Bluetooth communication output is connected with the input of bluetooth-communication unit 4, and its voice wake-up signal input is connected with the wake-up signal output of voice wake up process unit 2 simultaneously.
As shown in Figure 1, the output of audio collection unit 1 is connected with the input of voice wake up process unit 2.What audio collection unit 1 was used is common recording circuit
Described audio collection unit 1, the audio analog signals collecting is converted into digital signal, again by digital data transmission to voice wake up process unit 2, voice wake up process unit 2 is received after audio digital signals, by preset phonetic algorithm Treatment Analysis, if find that the feature of the special sound instruction that phonetic feature is preset with it conforms to, represent to have triggered voice wake-up signal, this preset phonetic algorithm is existing phonetic algorithm, can use existing comparatively ripe phonetic algorithm, also can use news to fly IVW3.0 voice and wake algorithm up, voice wake up process unit 2 adopts the digital processing units such as DSP, for example, adopt the digital processing units such as M0 or DSP, or directly embed algorithm in main control unit, master control processing unit 3 is exported to by this signal in voice wake up process unit 2, otherwise be considered as invalid phonetic feature.
Described main control unit 3 is received after the wake-up signal from voice wake up process unit 2, can define arbitrarily the meaning of this signal, is translated into a kind of specific Bluetooth communication instruction, exports to bluetooth-communication unit 4 and completes specifically and perform an action.
The not detailed disclosed part of the utility model belongs to the known technology of this area.
Although above the illustrative embodiment of the utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of embodiment; to those skilled in the art; as long as various variations appended claim limit and the spirit and scope of the present utility model determined in; these variations are apparent, and all innovation and creation that utilize the utility model design are all at the row of protection.
