Specifically, the spectrum showing different frequency components of a sound is called a sound power spectrum, and there are three basic forms in terms of identifying timbre features: the instant power spectrum reflects the energy state of each frequency at a specific moment of the voice; the short-time power spectrum is a spectrogram of energy between two time points in the speech stream of one or more syllables along with frequency distribution; the long-term power spectrum is represented by the average probability of different spectral components in speech, which can be expressed as a long-term average spectral density. In this embodiment, if the real-time power spectrum, the short-time power spectrum, or the long-time power spectrum of the sound signal of the sounding body is different, the sounding body is considered to be a different sounding body.
Specifically, a voiceprint recognition technology may be used, in which a voiceprint recognition is performed by converting a voice signal into an electrical signal and then using a computer, and if the voiceprint features extracted based on the voice signal are different, the sound-producing body is different. By utilizing the voiceprint recognition technology, the accuracy of obtaining the sounding body can be further improved.
In another embodiment, the infrared device in the hearing device can also be combined to identify the sound-producing bodies around the user. For example, the infrared device of the hearing device recognizes that five different objects are around, and further, the microphone of the hearing device acquires sound signals of the five objects; if the sound signal of the object is detected, taking the object as a sound producing body; if the sound signal of the object is not detected, the object is not used as a sound producing body.
In this embodiment, a plurality of sound producing bodies are accurately obtained through a tone recognition algorithm, so that it is ensured that the target sound producing body can be correctly selected.

acquiring a target position selected by a user;
acquiring sounding bodies in the target orientation from the plurality of sounding bodies;
if one sounding body exists in the target position, taking the sounding body as the target sounding body; alternatively, the first and second electrodes may be,
if a plurality of sounding bodies exist in the target position, obtaining a distance mode selected by a user in advance, and determining the target sounding body based on the distance mode selected by the user in advance.
6. A directional localized listening method as claimed in claim 4 or 5, characterized in that said step of determining said target sounding body based on a distance pattern preselected by said user comprises:
acquiring the intensity of a plurality of sounding body sound signals;
calculating and obtaining the distance between the sounding body and the user based on the strength of the sound signal;
and if the distance between the sounding body and the user is within the distance range corresponding to the distance mode selected by the user in advance, taking the sounding body as the target sounding body.
7. The directional localized listening method of any one of claims 1-5, wherein said step of obtaining a plurality of sound-producing volumes within an identifiable range of said hearing device comprises:
obtaining sound signals of the sound-producing bodies each within the recognizable range;
and identifying the sound signals by using a tone identification algorithm to obtain a plurality of sounding bodies.
8. A computer program product, comprising a computer program which, when being executed by a processor, carries out the steps of the directional localized listening method according to any one of claims 1-7.
9. A computer storage medium, characterized in that the computer storage medium has stored thereon a directional listening method program, which when executed by a processor performs the steps of the directional listening method according to any one of claims 1-7.
10. A hearing device comprising a memory, a processor and a directional localized listening method program stored on said memory and executable on said processor, said processor implementing the steps of the directional localized listening method according to any one of claims 1-7 when executing said directional localized listening method program.
