Final answer:
The sales associate's communication with a phone customer is best projected through voice tone and clarity.
Step-by-step explanation:
The sales associate's communication with a phone customer is best projected through voice tone and clarity. When communicating over the phone, body language and facial expressions are not visible, so the sales associate needs to rely on their voice tone and clarity to effectively convey their message and establish a positive connection with the customer. By using a professional and friendly voice tone, the sales associate can create a pleasant experience for the customer and ensure clear communication.
