Speech recognition neural network

Applying neural networks for speech recognition was reintroduced in late 1980s. Neural networks first introduced in 1950 but for some practical problems they were not that much efficient. In the 1990s, the Bayes classification is transformed into the optimization problems, which also reduces the empirical errors Neural Network Architecture. We will begin by discussing the architecture of the neural network used by Graves et. al. However, the architecture of the neural network is only the first of the major aspects of the paper; later, we discuss exactly how we use this architecture for speech recognition A novel system for effective speech recognition based on artificial neural network and opposition artificial bee colony algorithm, International Journal of Speech Technology (2019).

Speech Recognition with Deep Recurrent Neural Networks

forward neural networks have been around for more than two decades [1, 2], it is only recently that they have displaced Gaus-sian mixture models (GMMs) as the state-of-the-art acoustic model. More recently, it has been shown that recurrent neural networks can outperform feed-forward networks on large-scale speech recognition tasks [3, 4] network (RNN) and convolutional neural network (CNN). The core module can be viewed as a convolutional layer embedded with an RNN, which enables the model to capture both temporal and fre-quency dependance in the spectrogram of the speech in an efficient way. The model is tested on speech corpus TIMIT for phoneme recognition and IEMOCAP for. Then around 2012, Deep Neural Networks (DNNs) revolutionized the field of speech recognition. These multi-layer networks distinguish sounds better than GMMs by using discriminative training, differentiating phonetic units instead of modeling each one independently. But things really improved rapidly with Recurrent Neural Networks (RNNs. Neural networks approach the problem in a different way. The idea is to take a large number of handwritten digits, known as training examples, and then develop a system which can learn from those training examples. In other words, the neural network uses the examples to automatically infer rules for recognizing handwritten digits The revolution started from the successful application of deep neural networks to automatic speech recognition, and was quickly spread to other topics of speech processing, including speech analysis, speech denoising and separation, speaker and language recognition, speech synthesis, and spoken language understanding
