Consistently making sales relies as much on doing the small things well as it is does doing the big things. One of the "little" things a salesperson can do to improve their ability to make sales is to improve their tone of voice.
Research shows that up to 38% of communication relies on the tone of voice of the person speaking. Since people buy things from people they trust, then having an authoritative tone of voice will help you to build that trust far more frequently than focusing exclusively on the the words you say. It doesn't matter how great your product or service is, what matters is how great your prospect thinks your product or service is. If you can't communicate that effectively, people won't buy from you.
Improve your tone of voice, improve your ability to sell.
