If you heard the voice would you believe or would you commit? I guess it depends what the voice said and even how it was heard? For that voice could be misunderstood as being the one when it was a Demon or even a psychotic episode. How could you know if you were the only one who heard and would you dare ask others if they ears, minds and souls were listening as well? Would you respond to the voice or be too afraid to comment. Maybe it all depends not only what is said and how it is said but also how it makes you be. If this voice makes you a better person in your life and the life of others then listening /following should be the path that you take but if that voice does the opposite then it’s best to close those ears and seek professional help.
