  • Why and how

Base speech recognition on hitting a volume threshold (eg. 50%) instead of words

Although it is dependent on a game mechanic that requires a simple timed binary input rather than multiple choices, relying solely on a volume threshold reduces the vocal requirements to simply being able to make a voluntary sound, so even non-verbal players are able to trigger the action. It also significantly reduces development costs, as speech recognition algorithms are not required.
