Supported Platforms

Target

The Unity WebGL Speech Package is created for Unity version 5.3 or better. This includes support for Unity 2017.X, 2018.X, and 2019.X. This package combines the Unity WebGL Speech Detection and Unity WebGL Speech Synthesis packages. This package was originally created for the WebGL platform and supports other platforms using a Speech Proxy. This package requires a browser with the built-in Web Speech API, like Chrome. Speech detection and synthesis requires an Internet connection. The browser compatibility indicates which browsers have the Speech API implemented. The languages page shows what languages are supported by the Speech API.

FAQ

  • To avoid constant Microphone security prompts, host WebGL builds on secure HTTPS sites. Take a look at the online demos to see how that works.

  • Speech can work on mobile as a WebGL build. Launch the Chrome browser app on mobile and load your WebGL page in the Chrome app.

  • WebGL can take a long while to build. For faster development, try the Speech Proxy. This enables speech in the editor and standalone Windoows/Mac builds without the long wait times.

  • Sometimes the browser speech mechanism can crash. It can happen. If speech stops working, just close all of the browser windows and relaunch which should fix the issue.

Note: In December of 2018, Chrome added a speech restriction that the speak() method can't be invoked until a web page has some user interaction.
