Description of drawings
Fig. 1 is the synoptic diagram that voice processing apparatus of the present invention acts in the speech processes process.
Fig. 2 is the circuit diagram of embodiment of the invention voice processing apparatus.
Fig. 3 utilizes voice processing apparatus among Fig. 2 to realize that background music or voice eliminate the synoptic diagram of process.
Embodiment
Following divided data part and control part assign to introduce the speech signal processing device of present embodiment, as shown in Figure 2.
Data division comprises analog to digital conversion (ADC) module (having storer ADC MEM), digital signal processor interface (DSP_IF) module, digital signal processor (DSP), program storage (P-MEM), data-carrier store (X-MEM), input-buffer (In BUFFER), output buffers (Out BUFFER), digital to analog conversion (DAC) module (having storer DAC MEM), and MUX (MUX).In order to represent conveniently, P-MEM, X-MEM, InBUFFER, Out BUFFER unification are used P, X, Y MEM In﹠amp among the figure; Out Buffer frame table shows.Y MEM represents another data-carrier store of DSP, will relate at control section.The digital signal processor interface module can be selected existing product as required for use, and when multi-path voice was imported, the analog to digital conversion module can have a plurality of.
Mike imports MIC IN is transformed to 16BIT through the analog to digital conversion module numerical data ADC OUT; These data are deposited in the input-buffer by the digital signal processor interface module; DSP is by DSP_IF module and each storer and control section communication, instruction fetch from program storage, and the dsp operation instruction of fetching data is with the taking-up of the data in the input-buffer and deposit in the data-carrier store; DSP presses the data processing algorithm operating instruction, and there is another location in the data-carrier store in the data after handling; DSP deposits these data in the output buffers by DSP_IF by given pace; The digital to analog conversion module is taken out output data DSP_IF OUT and it is transformed into simulating signal by the frequency period ground of output sampling rate and outputs to MUX from output buffers; Another road of MUX is input as Mike and imports MIC IN, and be control signal with chip by-passing signal BYPASS, if the BYPASS signal is 0, with the output of digital to analog conversion module output signal DAC OUT as chip, otherwise, Mike is imported the output signal DAC OUT of MIC IN as chip.Its effect is directly to export voice when not needing speech signal processing device work.
Control section comprises that mainly main control interface (HIF) module and power supply open (POR) module that resets.
Main control interface (HIF) module provides the interface of the register in external piloting control coremaking sheet (HOST) visit ADC, DAC and the DSP_IF module, reaches the purpose of each module of control; External piloting control coremaking sheet can carry out bus by the main control interface module and switch, and program or data are downloaded among another data-carrier store Y MEM of P MEM, X MEM or DSP; External piloting control coremaking sheet can also be by the command register block among the main control interface module accesses DSP_IF, and this group register also can be visited by DSP, thereby can realize the communication of HOST and DSP; Power supply is opened and is resetted (POR) module when the 1.8V power supply electrifying, for whole device provides reset signal.
According to the difference of dsp software, this speech signal processing device can be realized all or part of following function: (1) ONE-MIC algorithm: can eliminate ground unrest stably.(2) TWO-MIC algorithm: can eliminate background sound or music.(3) ADD-NOISE algorithm: can add ground unrest or voice.(4) PITCH-SCALE algorithm: can change the intonation of voice, as male voice is become female voice, female voice becomes male voice.(5) DISTANCE-ADOPT algorithm: can adapt to the variation of phonetic entry distance.But, emphasis of the present invention and is indifferent to the concrete treatment scheme of these algorithms on the structure of speech signal processing device.
Be that example is introduced the process of utilizing this device to realize background music or voice elimination with the TWO-MIC algorithm below, as shown in Figure 3.
The TWO-MIC algorithm utilizes a Mike mainly to pick up speaker's voice signal VOICE, and another Mike picks up background sound or music noise NOISE; Acoustic vibration signal becomes analog electrical signal MIC1 IN and MIC2 IN after picking up through Mike, and this two path signal is transformed to digital signal ADC1 OUT and ADC2 OUT respectively through analog to digital conversion modules A DC1 and ADC2; DSP carries out the TWO-MIC algorithm, after voice and noise data are handled, generates clearly noise free data and gives digital to analog conversion module DAC; DAC is simulating signal DAC OUT with digital data converting and gives speaker's mobile phone (MOBILE FOR TALKER); Speaker's mobile phone is passed to obedient person's mobile phone with signal by wireless mode (WIRELESS), and obedient like this person has just clearly heard the speaker's voice through noise remove.
