Strong interpersonal skills create trust and emotional comfort.

Verbal Communication Skills

Positive Language

Replace negative expressions with constructive alternatives.

Negative

Positive

“I can’t do that.”

“Here is what I can do for you.”

“You are wrong.”

“Let us review the information together.”

“That is not my department.”

“I will connect you with the right person.”

Tone of Voice

Tone communicates attitude. A calm, warm, and confident tone is usually most effective.

Telephone Communication
