In the following, by being further detailed to the unlocking terminal equipment in this example embodiment and using starting method.
In step s 110, a unlock voice signal is received under the screen lock state of the terminal device.
In this example embodiment, after the terminal device owner lights the screen of terminal device, unlock voice can be issued
Signal, and then the terminal device can obtain unlock voice signal by audio collection modules such as microphones.
Step S120, content of text information, the vocal print feature information of the unlock voice signal are obtained.In addition, in this hair
In other bright exemplary embodiments, it can also obtain in the unlock voice signal and assist in identifying other letters such as characteristic information
Breath.For example:
Such as one section of the user's typing voice " open sesame " for unlock, terminal device is got for unlock
After " open sesame " this section unlocks voice signal, speech recognition can be carried out, identifies content of text information " open sesame "
This four words.Such as one section of the user's typing voice " I will see video " for unlock, terminal device is got for unlocking
" I will see video " this section unlock voice signal after, speech recognition can be carried out, identify that " I will see content of text information
This five words of video ".For example, one in deep neural network model, Hidden Markov Model, gauss hybrid models can be passed through
Kind or a variety of models carry out speech recognition to each unlock voice signal, obtain corresponding text information.For example, can lead to
It crosses Hidden Markov Model to model timing information, after a state of given Hidden Markov Model, passes through maximum
It is expected that the methods of value-based algorithm is modeled based on probability distribution of the gauss hybrid models to the speech feature vector for belonging to the state；
After modeling successfully, then speech recognition can be carried out to unlock voice signal, obtain corresponding content of text information.
" open sesame " and " I will see video " this section unlock in voice signal, and vocal print feature information includes tone, vibration
Width, loudness etc.；About the extraction of vocal print feature information, will illustrate in following step S130.
Step S130, the vocal print feature information is matched: if the vocal print feature information and prestore vocal print spy
Sign matching, then go to step S140；Otherwise, step S170 is gone to.
In this example embodiment, described to carry out matching to the vocal print feature information may include step S131 to step
S134.Wherein:
In step S131, after training speech signal pre-processing, mel-frequency cepstrum coefficient is extracted as training characteristics
Vector.It prestores password for example, can repeatedly read first in this example embodiment by user first and repeatedly reads second to prestore
Password obtains training voice signal, then carries out the pre- places such as preemphasis, framing, adding window and end-point detection to training voice signal
Reason；Then, Fast Fourier Transform (FFT) is carried out (for example, making quick Fu to the signal of adding window to pretreated trained voice signal
In leaf transformation), obtain spectrum distribution information, and take absolute value to the frequency spectrum and obtain amplitude spectrum.The amplitude spectrum is set to pass through packet
The filter group of multiple Gaussian band-pass filters is included, and calculates the logarithmic energy of each Gaussian band-pass filter output；Gauss filter
Wave device both ends be gradually decay and be it is symmetrical, each subband of trained voice signal and its adjacent sub-bands can be retained
Relevant information reduces distortion.Bring the logarithmic energy of each Gaussian band-pass filter into discrete cosine transform, extraction obtains
The mel-frequency cepstrum coefficient.Certainly, it in other exemplary embodiment of the present invention, can also calculate by other means
The mel-frequency cepstrum coefficient of voice signal is trained, does not do particular determination to this in the present exemplary embodiment.
In step S132, using self-adaptive kernel Fuzzy C-Means Cluster Algorithm, each training feature vector is gathered
Alanysis prestores vocal print feature described in obtaining.
The self-adaptive kernel Fuzzy C-Means Cluster Algorithm of the present embodiment can divide the set of each training feature vector
For multiple subsets；It, can be compared with specifically, the phonetic feature of user is mapped to high-dimensional feature space by using kernel function
Useful feature is differentiated, extracted and amplify well, expands the difference between mode class, and the speaker for improving Short Time Speech knows
Other performance.Meanwhile according to the width of the adaptively selected Gaussian kernel of the dispersion degree of data set, do not need to go through a large number of experiments
Determine suitable value.Moreover, in each cluster iterative process, according to the distribution situation adaptive updates of current cluster centre
Gaussian kernel width provides different flexible abilities to characteristic in higher dimensional space, is conducive to find in more preferably cluster
The heart avoids fall into local optimum to a certain extent.
In step S133, after the unlock speech signal pre-processing, extract described in the conduct of mel-frequency cepstrum coefficient
Vocal print feature information.The step is similar with step S131, is carried out in quick Fu to pretreated unlock voice signal
Leaf transformation obtains spectrum distribution information, and takes absolute value to the frequency spectrum and obtain amplitude spectrum；Make the amplitude spectrum by including more
The filter group of a Gaussian band-pass filter, and calculate the logarithmic energy of each Gaussian band-pass filter output；It will be each described
The logarithmic energy of Gaussian band-pass filter brings discrete cosine transform into, and extraction obtains the mel-frequency cepstrum coefficient.Therefore not
It repeats again.
In step S134, calculates the vocal print feature information and prestore the distance between vocal print feature, and according to described
Vocal print feature information described in Distance Judgment prestores whether vocal print feature matches with described.
