# How can I get voice recognition features into the Unity Game Engine? [closed]

How can I get voice recognition features into the Unity Game Engine? Is there a plug-in or a framework (hopefully freeware) that I could use? If so, do you have any ideas on how to install it? Also, how much of a problem would there be with background noises in the game interfering with the voice inputs into the game? Are there any examples of games on the market that use this? (besides for Spain 3D for the Torque Game Engine).

• All FOSS free-text transcription systems are generally terrible. Almost certainly not worth the effort it will take unless you are willing to shell out \$ to work with someone like Nuance. – coderanger Mar 29 '11 at 20:13
• @coderanger: Free-text transcription is hardly the only use of voice recognition, and probably least likely to be necessary in games. – user744 Mar 29 '11 at 20:34
• Sure, but if you know enough about speech recognition to build your own language model, you probably wouldn't be asking on here :-) – coderanger Mar 29 '11 at 22:42
• This may have been closed, but the answers could be misleading as of Unity 5.4. If you're targeting windows alone, you can make use of the UnityEngine.Windows.Speech namespace. KeywordRecogniser and DictationRecogniser are the two classes of interest. – zcabjro Nov 10 '16 at 9:41
