Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] The principle based on the realization of the present invention is such that for the majority of people, everyone will have multiple states, such as sick state, good state, fatigue state, hunger state, etc. Through our investigation, it is found that people are in different states. The frequency of the sound sent under the state is different, so it is possible to judge the state of people by sound. The present invention is based on this idea to distinguish the frequency of sound by a specific algorithm to obtain the state of people.

Abstract

The invention is applicable to the technical field of audio frequency discrimination, and provides a recommendation method on the basis of sound discrimination. The recommendation method includes acquiring sound which is generated when a user reads specific characters; extracting the sound to acquire a frequency waveform graph of the sound and the time; transforming the frequency waveform graph to obtain a frequency waveform graph in a set time range, and subtracting vectors of the frequency waveform graph in the set time range from vectors of a preset standard frequency waveform graph to obtain vector difference between the frequency waveform graph in the set time range and the preset standard frequency waveform graph; querying a preset mapping table of vector difference and states according to the obtained vector difference to obtain a state corresponding to the user. The recommendation method in a particular implementation mode has the advantage that the physical state of the user can be discriminated according to the sound generated by the user.

Description

technical field [0001] The invention belongs to the technical field of audio discrimination, in particular to a method and system for recommending audio discrimination. Background technique [0002] Sound is a pressure wave: when playing a musical instrument, tapping on a door, or knocking on a tabletop, their vibrations cause the medium—air molecules to vibrate rhythmically, causing the surrounding air to change in density and form a dense and alternating pattern. Longitudinal waves, which create sound waves, persist until the vibration dies away. [0003] Sound is a kind of wave, and frequency and amplitude have become important attributes to describe the wave. The magnitude of the frequency corresponds to what we usually call pitch, and the amplitude affects the magnitude of the sound. Sound can be broken down into a superposition of sine waves of different frequencies and intensities. This transformation (or decomposition) process is called Fourier Transform (FourierTr...
