2021 iFlytek Bird Song Recognition Competition

The Bird Song Recognition Challenge aims to advance automated bird song recognition technology by predicting the bird species present in each test audio clip.

We explored various feature extraction methods and data augmentation techniques, applying image classification algorithms to audio spectrograms. Multiple models were evaluated, including CNN, CNN feature extraction combined with sequence models (LSTM/Transformer), and Vision Transformer. Ultimately, model ensembles were employed to enhance performance.
