The Neural Network (NN ) based Speech Synthesis System We can immediately see some familiar file and directory names, like doc for documentation, egs for examples, src for source code, etc.įirst things first, we should always start investigating new code with the README file: $ cat README.md $ cd $ lsĬOPYING CREDITS.md doc egs INSTALL LICENSE misc README.md src test tools Résolution des deltas: 100% (734/734), done.Įasy as that! Now let’s take a peek into what we just downloaded. Remote: Total 1515 (delta 0 ), reused 0 (delta 0 ), pack-reused 1514 Like good open-source software, the Merlin toolkit is hosted on GitHub and can be easily downloaded (cloned) with a single line of code: $ git clone Merlin is free software, distributed under an Apache License Version 2.0, allowing unrestricted commercial and non-commercial use alike. Merlin comes with recipes (in the spirit of the Kaldi automatic speech recognition toolkit) to show you how to build state-of-the art systems. The system is written in Python and relies on the Theano numerical computation library. It must be used in combination with a front-end text processor (e.g., Festival) and a vocoder (e.g., STRAIGHT or WORLD). Merlin is a toolkit for building Deep Neural Network models for statistical parametric speech synthesis. Here is a nice, concise description of the toolkit quoted directly from the official CSTR Merlin site: More specifically, I will show which files are required by scripts, which files are generated by scripts, and how the main demo script run_demo.sh proceeds from data preparation to training to synthesis.

However, I won’t get into any of the algorithms behind DNNs or speech synthesis. In addition to showing and explaining the commands needed to install and run Merlin, I will also take some time to show how the scripts work and dive into the file structure expected by Merlin. In the following, I will display all the commands needed to (1) install Merlin from the official GitHub repository as well as (2) run the included demo. This post is a short introduction to installing and using the Merlin Speech Synthesis toolkit.
