Construction method and device of bird sound recognition model, computer device and storage medium

Abstract

The invention relates to the field of sound recognition and discloses a construction method and device of a bird sound recognition model, a computer device and a storage medium. The construction method comprises: acquiring bird sound samples that include sound fragments, wherein each bird sound sample corresponds to one bird name tag; extracting Mel-frequency cepstrum features from the sound fragments to obtain multiple spectrums of the sound fragments; subjecting the spectrums to feature extraction and dimensionality reduction to obtain feature graphs corresponding to the sound fragments; subjecting the feature graphs to voiceprint feature encoding to obtain voiceprint feature vectors; inputting the voiceprint feature vectors into a capsule network for training, and training to acquire abird sound recognition model that includes the trained capsule network. The bird sound recognition model acquired herein is suitable for processing sound fragments containing bird sound and recognizing types of birds.

Description

Technical field [0001] The present invention relates to the field of voice recognition, and in particular to a method, device, computer equipment and storage medium for constructing a bird voice recognition model. Background technique [0002] In nature, human production and life have a very large impact on birds. On the contrary, the living conditions of birds can reflect the state of human living environment to a certain extent. Therefore, it is necessary to establish a monitoring station for birds to obtain the living conditions of birds. [0003] However, many bird monitoring sites are often in unmanned areas, and the monitoring of birds often relies on monitoring personnel to monitor the surveillance video obtained by the monitoring sites. This way of monitoring, on the one hand, has high requirements on the monitoring personnel, on the other hand, it also has high requirements on the monitoring equipment. Therefore, the existing monitoring method is often to record audio d...
