Handling customers over the phone is far from easy. Agents must be prepared to handle customer questions on various topics, often with little time to prepare between calls. This means they need to have extensive product knowledge and quick-thinking skills. The complexity amplifies when considering that a staggering 71% of customers today anticipate tailored and personalized interactions.

However, even experienced agents sometimes struggle to find the right information when faced with an unfamiliar or complex inquiry. This is where Call Whisper comes in. It gives agents key customer data before or during a call through screen pops, voice recordings, or real-time coaching from a manager that only the agent can hear.

Let’s understand call whisper in-depth, including how it works and why you must invest in call whispering!

Expert Advice

"If you want to strengthen your business presence in Australia, one key strategy is to secure a local phone number. Local numbers give your business a more localized and trustworthy image, which can be crucial in building customer trust and loyalty. They also make it easier for customers in a specific region to reach out to your business, leading to increased conversions and sales. "

What is a Call Whisper?

Call Whisper is an innovative call center technology that empowers agents with the right information at the right time during customer interactions. It uses audio feeds, screen pops, and real-time coaching to silently provide agents with customer data and suggested responses without the customer hearing. This equips agents to have more personalized, effective conversations that drive greater first-call resolution, customer satisfaction, and employee productivity.

There are two main types of call whisper functionality:

  • Standard Call Whisper: Gives agents key customer information like account data or IVR selections through screen pops or pre-call recordings. This lets them prepare right when the call starts.
  • Live Call Whisper: A supervisor listens in real-time and whispers coaching tips and suggested responses directly to the agent as the call happens. This enables personalized guidance at the moment the agent needs it most.

How does Call Whisper Work?

Call whisper works with other call center software features, like call barging, call routing, and auto dialer tools. Here’s a step-by-step process on how the call whisper works.

How does Call Whisper Work?

  1. Agent receives a call: When an agent receives an incoming call, the system’s AI or a supervisor can activate a call whisper feature.
  2. AI-powered whisper: Using speech recognition and NLP, Call Whisper’s AI automatically generates relevant whispers to the agent based on call context and historical interactions.
  3. Supervisor’s input: The manager looks at the list of active calls and selects the one they want to supervise. If required, they provide the agent instructions, tips, or information without the caller hearing anything.

It is worth noting that the exact working process of the call whisper feature depends on the platform you use, call volume, or the number of available managers. However, the steps mentioned above are the most common course of action.

What is the Difference Between Call Whispering and Call Monitoring?

Call whispering provides real-time assistance and guidance to agents during calls to improve their performance. In contrast, call monitoring is a broader function used for various purposes, including quality control and performance evaluation, often without direct interaction with the agent during the call.

1. Purpose

Call whispering is primarily used to provide real-time assistance and coaching to a call center agent during a live call with a customer. The agent can receive guidance or information without the customer hearing it. It’s meant to improve the agent’s performance and help them handle the call more effectively.

On the other hand, call monitoring is a broader feature that allows supervisors or managers to listen in on calls in real time or review recorded calls. This helps in quality control, training, compliance, and performance evaluation. It may or may not involve providing immediate feedback to the agent.

2. Agent Awareness

In call whispering, the agent knows they are receiving assistance or coaching during the call. They can hear the whispered instructions or see messages on their screen.

Agent Awareness

However, in call monitoring, the agent may not be aware that their call is being monitored, especially if it’s done for quality control or training purposes. The monitoring is typically for evaluation rather than immediate assistance.

3. Use Cases

Call whispering enhances agent performance by providing real-time support for challenging or complex calls. It helps agents handle calls more effectively, especially if they are relatively new or require assistance with specific issues.

On the other hand, call monitoring is used for various purposes, including quality assurance, compliance checks, training, and performance evaluations. It can also assess overall call center performance and customer interactions.
