Embodiment 1
[0058] Such as figure 1 As shown, this embodiment provides an intelligent recommendation method based on voiceprint recognition, including the following steps:
[0059] S1: Acquiring the collected sound information and the voiceprint features of the sound signal; in step S1, the collected sound information is preprocessed, and the preprocessing step specifically includes the following substeps:
[0060] S11a: Sampling the collected sound information at equal intervals to obtain sampling information; sampling the analog signal at equal intervals in the time domain, and the sampling frequency of the voice signal is 8-16kHz;
[0061] S12a: discretize the amplitude value of the sampled information waveform to obtain discretized information;
[0062] S13a: Pre-emphasize the discretized information; adopt a first-order pre-emphasis digital filter with 6dB / octave to improve high-frequency characteristics, and its transfer function form is: H(z)=1-μz -1
[0063] In the formula, μ i...
Embodiment 2
[0100] Embodiment 2 discloses an electronic device, which includes a processor, a memory, and a program, wherein one or more processors and memories can be used, and the program is stored in the memory and configured to be executed by the processor, When the processor executes the program, the intelligent recommendation method based on voiceprint recognition in Embodiment 1 is realized. The electronic device may be a series of electronic devices such as a mobile phone, a computer, and a tablet computer.
Embodiment 3
[0102] Embodiment 3 discloses a readable computer storage medium, which is used to store a program, and when the program is executed by a processor, the intelligent recommendation method based on voiceprint recognition in Embodiment 1 is implemented.

Abstract
The invention discloses a voiceprint identification-based intelligent recommendation method. The method comprises the following steps of obtaining collected sound information, and according to the sound information, obtaining a voiceprint feature; matching the voiceprint feature with a stored sample voiceprint feature set, wherein the sample voiceprint feature set is voiceprint features of all legal users of a terminal; performing attribute extraction on the obtained sound information to obtain attribute feature words; and according to the attribute feature words and a user knowledge library,obtaining a user recommendation list, wherein the user knowledge library comprises user interactive data and knowledge information. The invention furthermore provides a voiceprint identification-basedintelligent recommendation apparatus. According to the voiceprint identification-based intelligent recommendation method, voice interactive contents are subjected to attribute extraction and a content list conforming to long-term preferences of users and current actual conditions is generated through a collaborative filtering algorithm by fusing the user knowledge library, so that the usage experience of the users is improved.
Description
technical field [0001] The invention relates to the field of data processing, in particular to an intelligent recommendation method and device based on voiceprint recognition. Background technique [0002] At present, personalized intelligent recommendation systems have been widely used in e-commerce, Internet advertising, mobile Internet and other fields at home and abroad, but the application of intelligent recommendation systems based on voiceprint recognition in the field of smart homes is almost blank. [0003] For smart homes based on voice interaction, users cannot log in through account passwords like traditional mobile phone or PC users. Therefore, the system cannot distinguish between different users of the same device. With voice-controlled smart home products, the time cost of human-machine voice interaction is much higher than that of mobile phones or PCs through peripheral input. Therefore, this requires that in the process of voice interaction between the ma...
