Convolutional Neural Network (CNN)-based Automatic Speech Recognition (ASR) systems leverage deep learning architectures, specifically CNNs, to model and transcribe spoken language into text. These systems utilize convolutional layers to effectively capture local temporal and spectral features of speech signals, leading to improved robustness and accuracy in diverse acoustic environments. CNN-based ASR models are often integrated with other neural network components, such as RNNs or transformers, to enhance sequence modeling capabilities.
