Setting up an audio input to control in game characters

Hey, i’m working on a small scale project and wanted to find out if it is possible to tweak the input controls so that rather than using left and right to control a characters direction, using real world sound through a microphone to play. For example, when the user inputs a command such as saying “Right” the character would travel right. Just looking if this is at all possible and or complicated to set up. For a real world example, looking to achieve something similar to the video game Yasuhati.
Thanks

You would probably need a software library for speech recognition. Then you can import it in your project and wrap it with your own UE4 classes.
