Better voice dial

Does anyone know a better voice dial up system. I have an s3 and the voice dial sucks. I use to touch my blue tooth it would say "say a command". I could say "dial" it would say "say the name or number" . It worked every time, understood me, was easy to use, and and I loved it. This s3 or the android system is worthless. Is it me or does someone have a suggestion? It's becoming law for hands free calling when driving. Phones I used 10 years ago were better than this thing.
