A customer contacts the company about a billing dispute. The agent mutes the line in order to check three different screens, but after twenty seconds, there is still no response, no acknowledgement and no update, just silence. The customer has no idea whether the call has been lost or whether anyone is looking into their issue.
That period of silence is known as dead air: it refers to a moment of quiet in a live conversation when neither of the two people involved is speaking, and the customer receives no indication that progress is being made. It is normal for there to be a few seconds of natural pause. However, dead air becomes an issue when the silence lasts for such a length of time that the customer begins to suspect the call is not under control, and over the course of thousands of daily interactions, it accumulates to form a noticeable decline in customer experience.
The guide explains the reasons behind dead air, the importance of dead air for contact centre performance, and the measures that reduce it in practice.
What is Dead Air
Dead air refers to a phase of silence that occurs during a live conversation between a customer and an agent, in which neither side is speaking, and the silence is not the result of the call being placed on hold or of the customer being given time to think or reply. It usually takes place because the agent is engaged in a task which the customer cannot see, such as looking up information in a knowledge base, switching between systems, or waiting for an application to load.
How Dead Air Differs from Hold Time
The hold time is made known; the agent tells the customer, who then hears the hold music and realises that the wait is deliberate and has limits. In contrast, dead air is not disclosed: the line remains open, no action takes place on it, and the customer gets no information as to what is happening. It is this lack of explanation that causes dead air to seem more unpleasant than an equivalent length of disclosed hold time.
At what times is it acceptable to be silent?
It isn’t the case that all silence is a problem. It is normal for there to be short pauses while the customer reads back a figure, when the agent is thinking honestly, or after the customer has finished speaking. Silence only becomes dead air when it goes beyond what the situation allows, and the customer is not given an explanation for it.
Common Causes of Dead Air
Dead air is usually the result of a combination of problems relating to the process, the tools, and the workload.
- Agent searching for information that the agent doesn’t have memorised
- Long system response times on CRM, ticketing, or core banking systems
- Manual data entry while the customer waits in line
- Knowledge gaps, especially among new or undertrained agents
- Customer delays, such as locating a document or account number
- Technical issues, including network lag or dropped audio
- Complex queries that require consulting more than one system or team
Why Dead Air Is a Problem
There is a direct and measurable connection between dead air and the metrics that contact centres are designed to optimise.
| Impact Area | Effect of Dead Air |
| Customer Experience | Silence is seen as a sign of inattention or incompetence, even if the agent is actually working on the case. |
| Customer frustration | The more often or for a longer period there is silence, the more likely it is that the situation will escalate or a complaint will be made. |
| Average Handle Time (AHT) | Each second of unproductive silence directly increases the length of the call. |
| First Call Resolution (FCR) | Agents distracted by system navigation are more likely to miss steps, leading to repeat contacts. |
| Agent Productivity | Time spent searching or switching systems is time not spent resolving the issue. |
| Customer Satisfaction (CSAT) | Silence is one of the most frequently given reasons for low satisfaction ratings in the surveys carried out after calls. |
Research that Forrester has carried out into customer effort has shown that the extent to which a customer feels effort during a service interaction is a more reliable predictor of loyalty than exceeding expectations. Dead air directly adds to that feeling of effort.
How to Reduce Dead Air in Customer Conversations
It is mainly an issue concerning operations and the use of equipment, not something that can be solved solely through training.
- Train agents to narrate pauses, so a wait is explained rather than being silent
- Use an AI agent assist to surface information during the call instead of after it.
- Provide instant knowledge retrieval across policies, products, and past interactions in one place.
- Automate repetitive tasks like note-taking and compliance fields instead of manual entry mid-call
- Improve CRM and system integrations to cut the number of screens an agent needs per call.
- Optimise internal processes so agents aren’t left waiting on another team mid-call
How AI Helps Eliminate Dead Air
Instead of asking the agents to speak more quickly or think less, AI gets rid of dead air by eliminating the manual steps that cause it.
- AI agent assists surfaces customer history, prior summaries, and next steps on the agent’s screen in real time, removing the need to search for context manually.
- AI voice agents handle conversational turns end-to-end, using conversational filler to mask processing delays instead of leaving the line silent.
- Conversation intelligence flags where and why dead air is occurring, giving teams visibility into a problem invisible in a standard call log
- Real-time knowledge assistance pulls the relevant policy or account detail into view as the conversation happens.
- Live call guidance prompts agents with next-best-action suggestions, reducing hesitation on unfamiliar queries.
- Automated note-taking removes the need to pause the conversation to type, since notes are generated after the call.
- CRM automation pushes call outcomes into connected systems, cutting live data entry
- Sentiment analysis flags rising frustration, including frustration caused by silence, before it escalates.
- Real-time quality monitoring tracks dead air as a measurable metric across live calls, not just in periodic audits.
Best Practices for Reducing Dead Air
- Keep customers informed during any necessary pause.
- Minimise the number of systems an agent switches between mid-call
- Standardise workflows so agents aren’t improvising under time pressure.
- Automate notes, data entry, and compliance checks
- Monitor conversations regularly, not just through periodic spot checks.
- Review dead air trends by analytics to catch systemic causes.
- Coach agents using specific, AI-surfaced insights over general feedback
How Convozen Helps Reduce Dead Air
The contact centre intelligence platform offered by Convozen is designed with the aim of eliminating the manual delays that lead to dead air. When on a call, agents are shown on their screen summaries of the customer’s conversation, insights into the customer’s mood, and the customer’s preferred way of speaking, so that they do not need to switch tabs in order to access the context. Conversation intelligence, together with real-time analytics monitors dead air and other quality indicators in 100% of the conversations, enabling supervisors to see where silence occurs and the reasons for it.
When it comes to voice AI interactions, Convozen’s system is designed so that the response latency remains at a conversational level, and filler masking is put into action if the processing time would otherwise cause a noticeable pause. The automated generation of call summaries and the integration with the CRM eliminate the need for manual note-taking and data entry, which usually causes a call to become unnecessarily silent, and the AI coaching makes use of the same insights to assist agents in developing habits that gradually reduce dead air.
Frequently Asked Questions
The silence which is not stated during a live call with neither side speaking generally, since the agent is carrying out a task that the customer cannot see.
The system had to be checked manually, the applications took a long time to load, data had to be entered manually, there were knowledge gaps and queries that required information to be checked across multiple systems.
It is normal to have short, natural pauses; only when the silence goes beyond what the situation justifies and is not explained does it become a problem.
It increases the amount of effort that is perceived and the average handle time, and is therefore often quoted as a cause of lower CSAT scores.
By providing agents with information in real time, automating the act of taking notes and entering data, and using conversational fillers to hide the processing delays that occur during voice AI calls.
Convozen provides customers with relevant context and suggests the best next steps during live calls, automatically generates notes and updates the CRM, and applies filler masking when interacting with voice AI.
