Embodiment Construction

[0025] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

[0026] A voice-based animal recognition method applied to a mobile terminal, the steps comprising:

[0027] a. Collect voice samples of several animal species, extract the sound wave characteristic parameters of each voice sample to establish a voiceprint model, and form a voiceprint database;

[0028] b. Obtain the animal voice signal to be analyzed, and separate at least one source signal from the animal voice signal by using monophonic voice separation technology;

[0029] c. Extract the voiceprints of each source signal and match them with the voiceprint models of each animal species in the voiceprint database;

[0030] d. Record the animal species corresponding to the successfully matched source signal.

[0031] Further, the step a of collecting voice samples of several animal species includes...

Abstract

Disclosed are a method and a device for identifying animals based on voice. The method includes acquiring voice samples of a plurality of animal species, extracting sound wave feature parameters of each voice sample to build vocal print models so as to build a vocal print database; acquiring to-be-analyzed animal voice signals, and using single track voice separation to separate at least one source signal from the animal voice signals; extracting vocal print of each source signal, and matching the vocal print with vocal models of various animal spices in the vocal print database; and recording animal species corresponding to successfully matched source signals. By using mobile terminals such a mobile phone to monitor animal voices around a user and voice spectral analysis, sound wave feature parameters of animal voices are extracted to be matched with models in the database, and accordingly animal species and quantitative distribution of animals around can be identified, and outdoor danger can be avoided. In addition, the device is interesting and fun to operate.

Description

technical field [0001] The invention relates to a mobile terminal with voice recognition function, in particular to a voice-based animal recognition method and device. Background technique [0002] Human beings have human language, and they can hear their voices to know them, because some voice characteristic parameters such as pitch and timbre in everyone's voice are difficult to change. Animals also have animal languages, and different animals make different calls. Each species and each individual of each species has its own unique call characteristics. For example, the calls of cats can be easily distinguished by human ears. and the barking of dogs. For the species that people are familiar with, the species can often be easily identified by the human ear, but it is difficult to identify the unfamiliar species, and the human ear has limited hearing and is easily affected by subjective cognition. [0003] When people are in the wild environment, sometimes they need to be ...
