The Chrome Speech Proxy is a Console application that proxies speech data to the Unity engine. The proxy supports speech detection and speech synthesis. The proxy requires admin or sudo rights to host the HTTP server. The Chrome Browser and Unity communicate with the proxy and the proxy passes data between the Chrome Browser and Unity. The Chrome Browser supports 120+ languages.

• Windows: Download Chrome Speech Proxy Installer (Windows)

• Mac: Download Chrome Speech Proxy (Mac)

• Test your browser for compatibility with the Chrome Speech Demo

• Launch the proxy which should start on the default 5000 port.

• Verify the proxy is running by browsing localhost:5000

• Click Enable user interaction to enable the text-to-speech API.

2 Start Unity and connect

3 Unity proxy management is now able to Launch and Close the proxy

4 Unity proxy management can open and close Chrome Proxy Tab when the proxy is running

The Mac build uses the Mono.framework to launch the proxy.

2 Unzip ConsoleChromeSpeechProxy.zip to a folder

3 Launch the proxy using the Mono.framework in the terminal

"/Library/Frameworks/Mono.framework/Versions/5.0.1/bin/mono32" "ConsoleChromeSpeechProxy.exe"

The Speech Proxy doesn't launch

• The default port 5000 may already be in use. Try a port other than the default and relaunch the proxy.

Detection doesn't seem to be working

• Only one Proxy window should be open at a time. Also make sure no other browser tabs/windows are using the Microphone. With multiple microphone apps open, the browser doesn't know which one to give focus.
