Which type of voice tone is least likely to promote a positive customer experience?

An annoyed or impatient tone is least likely to promote a positive customer experience because it can create a feeling of discomfort or anxiety for the customer. Such a tone may suggest that the representative is not interested in assisting the client or that their concerns are a burden. Customers typically seek a supportive and understanding interaction when they reach out for help, and an impatient tone can easily frustrate them or make them feel undervalued. In contrast, friendly and engaging, neutral and calm, and helpful and reassuring tones all foster a more welcoming atmosphere, encouraging open communication and reinforcing customer satisfaction.
