Abstract
Disclosed is a convenient anti-noise speech recognition electronic installation, comprising a speech recognition handler (1), a speech information memorizer (2) connected with the speech recognition handler in both ways and a microphone input (3) connected with the speech recognition handler in one way. In particular, a controlled gain control circuit (6) is provided between the microphone input (3) and the speech recognition handler (1). The installation not only can satisfy recognition the rate of whispering speech command inputting in quiet environment, but also can insure loud speech command inputting in noisy environment is not in high distortion. The convenient anti-noise speech recognition electronic installation can simultaneously suppress noise in the noisy environment and can enhance recognition rate of the speech command.
Description
Technical field
The utility model belongs to a kind of electronic installation that utilizes speech recognition technology to operate, and belongs to the electronic installation of may command input signal gain especially.
Background technology
In the daily life, speech recognition technology has been widely used in electronic installation, conveniently to use and to raise the efficiency.But speech recognition technology is higher to environmental requirement, and neighbourhood noise can directly influence the quality of phonetic entry, thereby the discrimination of influence input voice command.The very high mobile phone of popularity rate for example, just because its applied environment complexity, the discrimination of phonetic entry is too low and be difficult to accept for the user in noisy environment, makes the application of its speech recognition technology limited.The speech recognition electronic installation all adopts direct input method to transmit voice command in the prior art, and therefore debugging gain and signal to noise ratio (S/N ratio) in quiet environment change into that voice command will be flooded by noise in the noisy environment; And look after the noisy environment tuning parameter, change in the quiet environment signal and be difficult to identify the efficient voice order again a little less than too.
Summary of the invention
The utility model is to overcome the electronic installation that above-mentioned the deficiencies in the prior art part proposes a kind of adjustable gain.Its beneficial effect is both can satisfy the discrimination of importing voice command in the quiet environment softly, in the time of to need can guaranteeing in noisy environment big vocal input voice command again, unlikelyly causes that too big distortion suppresses noisy neighbourhood noise simultaneously, improves the discrimination of voice command.
The purpose of this utility model can realize like this:
Design, a kind of convenient anti-noise type speech recognition electronic installation of manufacturing comprise the voice message memory and the unidirectional microphone input that is connected of voice recognition processor and two-way connection with it; Especially also be provided with controlled gain between described microphone input and the voice recognition processor and adjust circuit.
Description of drawings:
Fig. 1 is the theory diagram of the utility model convenient anti-noise type speech recognition electronic installation;
Fig. 2 is the circuit diagram of described electronic installation.
Embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
A kind of convenient anti-noise type speech recognition electronic installation comprises that voice recognition processor 1 reaches the voice message memory 2 and the unidirectional microphone input 3 that is connected of two-way connection with it; Especially also be provided with controlled gain between described microphone input 3 and the voice recognition processor 1 and adjust circuit 6.
Among some embodiment, it can be automatic gain control circuit that described controlled gain is adjusted circuit 6, adopts the electronics mode, and ride gain is adjusted the gain of circuit.
Among other embodiment, described controlled gain is adjusted circuit 6 can comprise double-pole double site type keyswitch K and the damping resistance that is connected with its contact; Judge ambient conditions by the operator, adopt the open and close of manual adjustment K switch,, adapt to the needs of varying environment to be switched on or switched off damping resistance, and simple in structure, suitable.
Described convenient anti-noise type speech recognition electronic installation also comprises the loudspeaker output 4 that links to each other with described voice recognition processor 1, broadcasts Query Result, for the user provides friendly operation interface.
Described convenient anti-noise type speech recognition electronic installation also comprises the keyboard circuit 5 that links to each other with described voice recognition processor 1.This keyboard circuit is provided with " identification key " starter gear as speech recognition; Number of digital key etc. is set simultaneously as auxiliary input, means as a supplement under the situation of inconvenient phonetic entry are as the input of telephone number and other information.
In the practicality, described identification key links with described K switch, and the user can press still locking " identification key " according to current environmental selection, and ride gain is adjusted circuit 6.Press " identification key " back during quiet environment and decontrol, then the anti-noise K switch is not closed, and attenuator circuit 6 is not worked; Loud environment can be locked " identification key ", and then anti-noise K switch closure is started working attenuator circuit, and the user can press close to microphone input media 3 and roar order or the name that will discern.Voice are delivered to voice recognition processor 1 after 3 inputs of microphone input media are amplified; In voice recognition processor, carry out analog to digital conversion and retrieval voice message memory 2 contents, compare; Information in the voice message memory both can be prefabricated, also can start the junior scholar by " training study key ".Result according to comparison can obtain or information similar consistent with voice command, and carries out corresponding action by voice recognition processor 1.Electronic installation described in the utility model can be used for the voice telephone number book, also can be used for the telephone set of phonetic dialing.
