Webdio superresolution or frequency bandwidth extension. Early methods were based on the source-filter model of speech pro-duction and exploit DNNs to estimate the upper frequency envelope [3]. Inspired by the early success in image super-resolution [4], end-to-end audio-based solutions were pro-posed, based on wave-to-wave UNet [5], WaveNet [6 ... Web3. Speech Bandwidth Extension using DNNs 3.1. Spectral expansion using DNN Figure 1 shows a flow chart of our method. The proposed model is a four-layer feedforward DNN, including an input layer, two hidden layers and an output layer. In Figure 1, the dashed ar-row indicates the training phase while the solid arrow indicates the reconstruction ...
