Text To Speech From Wwise

Overview

This sample demonstrates how to generate WAV files using text-to-speech from Wwise directly.

Demonstrates:

• WAAPI ak.wwise.core.object.get
• WAAPI ak.wwise.core.audio.import
• Text to Speech using Windows Powershell and SpeechSynthesizer
• Wwise Command Add-ons

Requirements

• Wwise 2019.2.x or more recent
• Python 3.6 or more recent
• waapi-client python library
• Windows 10 and Windows Powershell

Setup

1. Install python 3.6 or more recent

2. Install python dependencies:

   py -3 -m pip install waapi-client

3. Create the Add-ons folder under %APPDATA%\Audiokinetic\Wwise

4. Unzip the git repository under: %APPDATA%\Audiokinetic\Wwise\Add-ons

   Note: ensure the Commands and waapi-text-to-speech folders are directly located under the Add-ons folder.

5. Restart Wwise or run the command Command Add-ons/Reload

How to use

1. Create a Sound SFX or Sound Voice object in the project.
2. Type some text in the Notes field.
3. Right-click the object, and select Generate Text-to-Speech.

How it works

The source code is located in main.py.

This script is using WAAPI and the Command Add-ons system. It will retrieve the selection from executed command and generate a WAV file for each selected Sound objects using Windows text to speech. The WAV files will be automatically imported in the project with WAAPI.
