A lightweight and robust method for blind wideband-to-fullband extension of speech
Jan Büthe, Jean-Marc Valin
Reducing the bandwidth of speech is common practice in resource constrained environments like low-bandwidth speech transmission or low-complexity vocoding. We propose a lightweight…

Very Low Complexity Speech Synthesis Using Framewise Autoregressive GAN (FARGAN) with Pitch Prediction
Jean-Marc Valin, Ahmed Mustafa, Jan Büthe
Neural vocoders are now being used in a wide range of speech processing applications. In many of those applications, the vocoder can be the most complex component, so finding lower…
