The time-delay neural betwork (TDNN) is widely used in speech recognition software for the acoustic model, which converts the acoustic signal into a phonetic representation. The papers describing the TDNN can be a bit dense, but since I spent some time during my master’s thesis working with them, I’d like to take a moment to try to demystify them a little.

With the Deep Speech network, constructing a new lexicon in Mandarin is unnecessary. Deep Speech uses a deep recurrent neural network that directly maps variable length speech to characters using the connectionist temporal classification loss function [4]. There is no explicit representation of phonemes anywhere in the model, and no alignment ...
Deep Speech Inpainting. Fig.1 Deep speech inpainting framework & training. Learn more about our deep speech feature extractor below.. We developed a deep learning framework for speech inpainting, the context-based retrieval of large portions of missing or severely degraded time-frequency representations of speech. Deep neural networks (DNN) have become increasingly effective at many difficult machine-learning tasks. However, DNNs are vulnerable to adversarial examples that are maliciously made to misguide the DNN's performance. The vulnerability may make it difficult to apply the DNNs to security sensitive usecases.

Since deep learning approaches can automatically learn the representations of data with multiple levels of abstraction, they impact almost every discipline of science and engineering, including the physical , chemical , medical , and biological sciences [5, 6].
Oct 14, 2016 · Typical speech processing approaches use a deep learning component (either a CNN or an RNN) followed by a mechanism to ensure that there’s consistency in time (traditionally an HMM). The deep learning component predicts what’s being uttered, i.e. phoneme , which is frequently based on a single 10ms frame of the input signal.

Ludwig is a toolbox that allows users to train and test deep learning models without the need to write code. It is built on top of TensorFlow. To train a model you need to provide is a file containing your data, a list of columns to use as inputs, and a list of columns to use as outputs, Ludwig will do the rest.
Deep feature losses for denoising were previously proposed in [17, 18], but were explored only for relatively high signal-to-noise ratios (SNRs) for a single task and network, and were not compared to baseline methods using the same transform architecture.
Index Terms: Speech denoising, speech enhancement, deep learning, context aggregation network, deep feature loss 1.

We present an end-to-end deep learning approach to denoising speech signals by processing the raw waveform directly. Given input audio containing speech corrupted by an additive background signal, the system aims to produce a processed signal that contains only the speech content. Recent approaches have shown promising results using various deep network architectures.
Denoising-based approaches: These methods utilize deep learning based models to learn the mapping from the mixture signals to one of the sources among the mixture signals. In the speech recognition task, given noisy features, Maas et al. [2] proposed to apply a DRNN to predict clean speech features.
