Despeect

A GUI and debugging tool for the Speect TTS library.

Introduction

What is DeSpeect?

DeSpeect is a graphical interface for Speect [Meraka Institute (2008-2013)], a library for the creation of vocal synthesis systems, which facilitates the inspection of its internal state during its execution and the writing of tests for its functionality.

Getting Started

Prerequisites

Speect Prerequisites

• git (minimum version 2.14.1)
• curl ( minimum version 7.55.1)
• ANSI C/ISO C90 GCC compiler (minimum version 5.0)
• CMAKE (minimum version 2.8)
• SWIG (minimum Version 3.0.10)
• libxml2-dev (minimum version 2.9.4)
• python-dev (minimum version 2.7.14)

Despeect Prerequisites

• Unix / Unix-like OS (DeSpeect has only been tested on Ubuntu 16.04 LTS)
• CMAKE (minimum version 2.8)
• ANSI C/ISO C90 GCC compiler (minimum version 7.0)
• Qt 5.9.0

Installing

You can run DeSpeect in two different ways, according to your needs:

1. Developer build

• Clone or download the repository
• Execute the build.sh script in the root directory

This will install Speect, create a build for DeSpeect in DeSpeect/build/ and run the related tests.

1. User build

• Clone or download the repository
• Execute the Installer.sh script in the root directory
• Select a destination folder for the installation

This will install Speect and create a build for DeSpeect, without running any test.

Running the tests

The tests for DeSpeect are implemented through the Google Test framework and they are run at every build by Travis CI.
In order to run the tests locally, you need to perform a developer build which runs the tests automatically. Once you have installed the application, you can run the related tests by entering the build directory (DeSpeect/build/) and using either the ctest or unit_tests commands.

Usage

Running the application

You can run DeSpeect in two different ways, depending on how decided to install it:

1. Developer build
   • Enter the bin directory through the DeSpeect/build/bin/ path
   • Start the application executing the main file

1. User build

• Enter the root install directory
• Start the executable called DeSpeect

Example - Visualizing the graph

In order to visualize a Speect internal graph, you just need to load a .json voice file clicking on the Load Voicebutton in the main window (sample voices are stored in the SpeectInstaller/voices/ directory), and subsequently execute Speect through the Run All or Run Step button. Notice that Run All will execute all the utterance processors, while Run Step will only run the first utterance processor (see Speect docs. The following is a detailed sample procedure of how to visualize a graph:

1. Start the application
2. Click on the Load Voice button
3. Open the file corresponding the SpeectInstaller/voices/cmu_arctic_slt/voice.json path (if you opted for a dev install) or DeSpeectInstall/Test/cmu_arctic_slt/voice.json (if you opted for a user install)
4. Select the desired utterance processors in the homonymous sidebar
5. Click the Run step button in order to execute the utterance processors list step by step, or click Run all in order to execute the whole list

Built with
