Trying It Out:

• Open TTSTest folder/project in Unity3D
• Change build setting to iOS
• Have an iOS device attached ( doesn't build for simulator by default)
• Build!
• Change iOS dev team id, provisioning & signing
• Tap the screen once it prompts
• It will speak a quote from HAL9000

Features:

• Lets you know when it starts speaking.
• Lets you know when it finishes speaking.
• Lets you know when it reads a specific word of the text.

See the TTSTest.cs class in TTSTest Unity3D project for details.

Index of Significant Locations:

• TTS_seriously_eralp.mov

  Video recording demo of the compiled Unity3D project on iOS

• /TTSTest

  Unity3D project containing the Plugin and the test implementation scene

  • Contains Scenes/TTSTest.unity scene. Which has the example implementation of the plugin

  • TTSTest object in hierarcy has c# script TTSTest.cs implementing the plugin and displaying test GUI

  • TTS/TTSPlugin prefab (also in hierarcy) has TTSPlugin.cs the Unity3D side of the plugin.

  • Files under TTS/Plugin/TTSPlugin, TTSPlugin.h & TTSPlugin.h are the native iOS side code of the implementation.

  • Actual files are here, the ones in Unity3DTTSPlugin xcode project are just relatively symlinked. The reason not being the other way is explained below.

• /Unity3DTTSPlugin

  XCode project for developing & testing the native plugin files

  • Running native iOS project will trigger the class responsible for doing the synthesis, for testing.

  • TTSPlugin.h & TTSPlugin.h are not actual files in this project but they are symlinked from unity project. Not the other way to avoid problems when building unity project

Notes:

• Generated XCode project is not provided since its mostly intermediate code

• The XCode project Unity3DTTSPlugin is not generated game code from Unity3D. It's used for developing the native side of the plugin

• Folder TTSTestXCode is ignored since its used for development in generating the intermediate Unity3D iOS XCode project.
