Fig. 3: the described speech processes flow chart that is used for the recipient of mobile phone of the embodiment of the invention.
Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
As shown in Figure 1, realizing the content of embodiment 1 of the present invention, can be that the device of the portable terminal by having voice processing effect is realized.
Tone color processing module 12 is used for default and stores the parameter of required audio-frequency information, is called by speech processing module 13;
Voice and picture synthesis module 14 are used for calling corresponding picture when receiving voice.
In conjunction with Fig. 1, by the combination of above-mentioned module, the described function with portable terminal of voice processing effect of the embodiment of the invention comprises:
From the recipient, when the words bell ring, speech processing module 11 is obtained the audio-frequency information that sends from the calling party, tone color control module 12 is used for parameter default and that store required audio-frequency information, speech processing module 13 is used for according to default parameter value the audio-frequency information that sends being put in caller and carries out the adjustment of parameter, voice and picture synthesis module 14 are used for calling corresponding picture, output at last when receiving voice.Wherein, the adjustment to parameter in the speech processing module 13 realizes by calculating audio-frequency information processing unit and control audio information process unit, and is not shown among Fig. 1.
From the calling party, after finishing dialing, speech processing module 11 is obtained calling party's audio-frequency information, tone color control module 12 is used for parameter default and that store required audio-frequency information, speech processing module 13 is used for according to default parameter value the audio-frequency information that sends being put in caller and carries out the adjustment of parameter, output at last.Wherein, the adjustment to parameter in the speech processing module 13 realizes by calculating audio-frequency information processing unit and control audio information process unit, and is not shown among Fig. 1.
And, the step of the parameter adjustment of above-mentioned audio-frequency information is specific as follows: the requirement that changes according to time span on time domain is carried out interpolation to signal or is taken out and cut, transform to frequency domain then, amplitude spectrum and phase spectrum are handled respectively, separate fundamental frequency and formant, and it is carried out independent regulation, the two the influence to this of make-up time length adjustment recovers time-domain signal at last during adjusting.
Wherein, the set-up procedure of above-mentioned fundamental frequency and formant position is specific as follows: a certain frame is carried out the interpolation of data point or take out and cut according to adjusting factor t on time domain; Transform to frequency domain, and be transformed on the polar coordinates, obtain phase spectrum I and amplitude spectrum II by rectangular coordinate; Amplitude spectrum II is extracted envelope, obtain envelope spectrum III, III is carried out convergent-divergent according to adjusting factor t * f on frequency axis, obtain adjusting the envelope spectrum IV of formant position, f represents the fundamental frequency adjustment factor; Point-to-point to amplitude spectrum II divided by envelope spectrum III, obtain composing V, the abscissa of spectrum V is carried out convergent-divergent according to adjusting factor t * p on frequency axis, point-to-pointly then multiply by adjusted envelope spectrum IV, obtain adjusted amplitude spectrum VII, p represents the formant position adjustment factor; To phase spectrum I, launch with the phase difference of consecutive frame, obtain between two frames actual value of phase change on each frequency, this is on duty to adjust factor t * p, then frequency axis is carried out convergent-divergent according to adjusting factor t * p, adjusted phase difference is added up again, obtain the adjusted phase spectrum VIII of present frame; Adjusted amplitude spectrum VII and phase spectrum VIII are transformed to rectangular coordinate, the time domain of remapping.
Independent adjustment is carried out in fundamental frequency and resonance branch position to signal on the above-mentioned frequency domain, fundamental frequency and formant position are separated, the fundamental frequency and the harmonic wave thereof of voice signal both can have been changed, can keep the formant position again simultaneously or the formant position arbitrarily be adjusted the independent change of realization tone color and pitch.
And, by interpolation or take out to cut digital signal realize is resampled, thereby elongate or shorten the time scale of voice, fundamental frequency and the formant position that changes compensated, realize the effect that separately word speed is changed.
After adopting scheme of the present invention, the user can obtain special audio according to the needs of oneself in communication process, can adjust tone color, tone, features such as word speed flexibly.
As shown in Figure 2, when described portable terminal caller was dialled, the method with voice processing effect was as follows:
Step 111 is prepared to phone with mobile telephone;
Step 112 is dialed the other side's cell-phone number;
Step 113 if seek out special sound effect, is then selected Audio Processing, and the words of not selecting Audio Processing are exactly raw tone output;
Step 114 is obtained the parameter of the audio-frequency information of calling party's voice;
Step 115 is carried out parameter adjustment to the calling party's that obtains voice;
Step 116, the special efficacy voice output;
Step 117, end of conversation.
As shown in Figure 3, when described portable terminal receives caller, have the method for voice processing effect:
The raw tone of the calling party's output described in the described step 213 can be through Audio Processing, also can be the normal speech of not passing through any processing.
As seen, embodiment 1 of the present invention and embodiment 2 have realized the processing to voice, make the user can obtain special sound effect, have realized tone color, tone, the adjustment of word speed.
In sum, more than be preferred embodiment of the present invention only, be not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present invention.
