Extracting acoustic features of user request voice data: firstly, carrying out voice recognition on voice data requested by a user to obtain a recognition text of the voice data requested by the user; specifically, the acoustic feature is generally a spectrum feature of voice data, and is used to express timbre information of a user, and in the prior art, the acoustic feature of the user may be expressed by the following features, and the embodiment of the present invention is not particularly limited herein: PLP (Perceptual Linear Predictive coefficient) features, FilterBank features, MFCC (Mel-Frequency Cepstral Coefficients) features, and the like.
Subsequently, the existing speech recognition method is used to perform speech recognition on the user request speech data (the specific extraction method is the same as the prior art, and the embodiment is not specifically limited herein), so as to obtain a corresponding recognition text. Further, according to the recognition text of the user request voice data, extracting the semantic features of the user request voice data by utilizing the prior art; the semantic features are used for representing semantic information of the user request voice data, and specifically can be represented by word vectors or sentence vectors of the user request voice data recognition text; the sentence vectors may be obtained by adding Word vectors of each Word in the recognized text and then averaging, the Word vector extraction method is the same as that in the prior art, for example, a Word2Vec technology is adopted to extract the Word vectors of each Word in the recognized text, and this embodiment is not limited specifically herein.
The user attribute features corresponding to the user request voice data are attribute information used for describing the user's own special attribute, and can be the gender, age, occupation and the like of the user. Taking age as an example, the attribute of sexual age is children, young, middle-aged and old, or under 10 years old, 10 to 30 years old, and over 30 years old. When various user attribute features are extracted specifically, the acoustic feature extraction is directly carried out according to user request voice data, specifically, a pre-constructed user attribute feature is utilized to determine model determination, the model is input into the acoustic feature of each user request voice data, and the acoustic feature is output as an attribute feature value of a user; taking the attribute characteristics of the user as age as an example, the input of a preset model is voice request data of the user, and the output of the model is a specific age attribute value, namely young, middle-aged or old (under 10 years old, 10 to 30 years old or over 30 years old); the present embodiment is not particularly limited herein. The user attribute feature determination model is generally a neural network model in a deep learning method, such as a deep neural network model, a convolutional neural network model, and the like, and the specific construction method is the same as that in the prior art and is not described in detail herein; the present embodiment is not particularly limited herein.
The speaker characteristics corresponding to the user request speech data are speaker information used for characterizing the user, and in order to prevent the user from influencing speaker characteristic extraction due to different channels or environmental phonemes, the specific speaker characteristics can be obtained by any means in the prior art, which is not specifically limited in this embodiment. In the following embodiment, two speaker characteristics, namely a TV-vector characteristic and a CNN-driver characteristic, are extracted by respectively using the fully variable factor analysis method and the deep neural network in the prior art.
The Gaussian mixture-generic background model (GMM _ UBM) is a mainstream method for obtaining speaker characteristics. GMM _ UBM utilizes a Gaussian function to fit the characteristics of each person when speaking, and takes the problem of insufficient voice data quantity into consideration, a small amount of data of the speaker is self-adapted through a Universal Background Model (UBM) to obtain a target speaker model; a certain section of voice of a certain speaker can be represented by a mean value super vector M; the method for analyzing the all-variable factor comprises the steps of projecting the mean value super vector M to an all-variable space T, and obtaining the all-variable factor w representing information of a speaker, namely i-vector characteristics without distinguishing a speaker space, a channel space and a residual error space, wherein M is a UBM mean value vector; the i-vector feature includes not only speaker information but also channel information and residual information, and therefore channel compensation is required. Because the embodiment is an automatic recommendation process, namely an unsupervised process, a Principal Component Analysis (PCA) technology is adopted immediately, high-dimensional data is projected to low-dimensional data, and a projection which can represent the original high-dimensional data most in the sense of minimum mean square error is searched; and finally, obtaining the speaker characteristic vector TV _ ivctor under the full-variable factor analysis method.
In the embodiment, a deep learning method, namely, a Convolutional Neural Network (CNN) is adopted to extract CNN-driver characteristics, the network input is the frequency spectrum characteristics (such as FBank characteristics) of voice data of a speaker, the network output is the characteristic vector representing speaker information, the obtained characteristic vector is subjected to dimensionality reduction by adopting PCA, and the speaker characteristic vector CNN-driver under the deep learning method is obtained after principal components are extracted.
On the basis of the above specific embodiments of the present invention, a content recommendation method is provided, where the interactive recommendation feature further includes a feature of whether to use recommended content.
It should be noted that, when the current target user uses the intelligent device for the first time to make a voice request, since the intelligent device has not requested the voice data recommendation content for the current user, the recommendation content characteristic of whether the user uses the intelligent device is null. In addition, after the current target user finishes recommending content for at least one time, the user category of the current target user in the recommendation knowledge base can be dynamically adjusted according to the recommendation content of whether the current target user uses the intelligent device or not, that is, the distance between the current user request voice data and the cluster center of each type of user request voice data in the recommendation knowledge base is recalculated according to the recommendation content of whether the current user uses the intelligent device or not, so as to obtain a new cluster category of the current user request voice data, and more appropriate content is recommendable to the current target user according to the category to which the newly calculated current user request voice data belongs.
On the basis of the above specific embodiment of the present invention, a content recommendation method is provided, which further includes: and adding the user category of the target user, the interactive recommendation characteristics extracted from the sample voice request data of the target user, the corresponding recommendation content of the target user and the corresponding relation among the three into the recommendation knowledge base.
