The phrases you can say are: Hi How are you doing? What's your name? Are you a real person? How do you think about me? Goodbye! Should I follow TRACK3R? What is a database? What is your favorite food? Can I change the volume on this?
(there's a secret phrase...) Any phrases that are not stored in the database won't work. Oh! And if you want any phrases to be added, put your phrase and answer in the comments!! It's a bit buggy because this is not the full version. The phrases are not case sensitive.
