With reference to Fig. 2, the embodiment of the present application provides a kind of living broadcast interactive method, comprising the following steps:
S201, speech recognition is carried out to the voice data of the main broadcaster of direct broadcasting room.
When it is implemented, the audio data of acquisition is sent to server by main broadcaster's client, by server to audio data It is handled, the voice data of main broadcaster is therefrom got in audio data, speech recognition is carried out to the voice data of main broadcaster.Specifically Ground, can be by removing the mute part in the audio data that main broadcaster's client acquires to VAD technology, to extract the language of main broadcaster Sound data.
When it is implemented, speech recognition can be carried out in the following way:
Whether first way is based on acoustic feature matching process, identify in the voice data of main broadcaster comprising being used to indicate The voice messaging for opening prize drawing specifically comprises the following steps: with reference to Fig. 3
S301, sub-frame processing is carried out to the voice data of the main broadcaster of direct broadcasting room, obtains several speech frames.
Specifically, sub-frame processing is carried out in voice data to main broadcaster, i.e., it is pre- the voice data of main broadcaster is cut into several If the sound bite of length, each sound bite is known as a speech frame, usually has between adjacent speech frame overlapping.
Specifically, sub-frame processing can be carried out to voice data by way of adding Hamming window, obtains several speech frames. By taking Fig. 4 as an example, long can choose of the window of Hamming window is 25 milliseconds, and it is 10 milliseconds that two frame window of front and back, which moves, and overlapping portion is 15 milliseconds, Then the length of each speech frame is 25 milliseconds, there is 15 milliseconds of overlapping part between two neighboring speech frame.
S302, acoustic feature extraction is carried out to each speech frame, obtains the corresponding acoustic feature vector of each speech frame.
When it is implemented, carrying out acoustics to each speech frame obtained by step S301 according to the physiological property of human ear The corresponding signal waveform of each speech frame is converted into a multi-C vector by feature extraction.It is extracted in above-mentioned steps S302 Acoustic feature vector can be the acoustic feature of any one following type: LPCC (Linear Predictive Cepstral Coding, linear prediction residue error) feature, filter FilterBank feature, MFCC (Mel-scale Frequency CepstralCoefficients, mel cepstrum coefficients) feature, PLP (Perceptual Linear Predictive, perception Linear prediction) feature.
S303, the corresponding acoustic feature vector sum of voice data for calculating main broadcaster are used to indicate the voice messaging for opening prize drawing Similarity between corresponding acoustic feature vector.
When it is implemented, being used to indicate the voice messaging (i.e. prize drawing enabled instruction) opened and drawn a lottery can unify to set, i.e., Each main broadcaster is all made of identical prize drawing enabled instruction, can also its proprietary prize drawing enabled instruction by main broadcaster's sets itself.Example Such as, prize drawing enabled instruction can be " starting to draw a lottery " or " starting prize drawing " etc..
Specifically, the corresponding acoustic feature vector of prize drawing enabled instruction can be extracted in the following way, and main broadcaster prerecords The corresponding voice data of prize drawing enabled instruction carries out sub-frame processing to the corresponding voice data of prize drawing enabled instruction, obtains several A speech frame carries out acoustic feature extraction to this several speech frame, obtains the corresponding acoustic feature vector of each speech frame, will Obtained acoustic feature vector is stored as the corresponding acoustic feature vector of prize drawing enabled instruction.It should be noted that step The type of the type for the acoustic feature vector that rapid S302 is extracted acoustic feature vector corresponding with prize drawing enabled instruction is consistent.
When it is implemented, main broadcaster can be determined by DTW (Dynamic Time Warping, dynamic time consolidation) algorithm The corresponding acoustic feature vector of voice data corresponding acoustic feature vector sum prize drawing enabled instruction between similarity.
If S304, similarity are more than preset threshold, the voice messaging for recognizing and being used to indicate and opening prize drawing is determined.
When it is implemented, preset threshold can be by those skilled in the art according to practical application request and similarity algorithm Accuracy factor simultaneously combines practical experience to determine, is not construed as limiting herein.
The second way carries out speech recognition to the voice data of main broadcaster, obtains speech recognition result (i.e. text data), It whether is determined in the voice data of main broadcaster based on speech recognition result comprising being used to indicate the voice messaging opened and drawn a lottery.
