WebSpeech is different from acoustic events, when one considers its phonetic structure. Hence, frame-based speech features may not be suitable for Acoustic Event Classification (AEC). In this paper, a novel method is proposed for the extraction of robust acoustic event specific features from the spectrogram using a left singular vector for AEC. WebLearn how to transform sound signals to a visual image format by using spectrograms. Build a speech classification model that can recognize sounds or spoken words by using convolutional neural networks (CNNs). Prerequisites Basic Python knowledge. Basic knowledge about how to use Jupyter Notebooks. Basic understanding of CNNs.
