Tech Terms: Post-Call vs. Real-Time Explained

Voice data is gold in the contact center – but when you can access it, it can change everything.

Whether you’re looking to boost agent performance in the moment or to generate insights after a conversation wraps, transcription plays a key role. But not all transcription happens the same way.

Real-Time vs. Post-Call Transcription: What’s the Difference?

Let’s break down two essential tech terms – Real-Time Transcription and Post-Call Transcription – and explore how smart contact centers use both to drive better outcomes and richer insights.

What Is Real-Time Transcription?

Real-Time Transcription (RTT) converts speech-to-text as the conversation happens.

Think of it as a live feed of the call – using AI-driven tools to enable agents and supervisors to react to what’s being said in the moment.

Why Use Real-Time Transcription?

• Live, In-call Agent Assist: Surface dynamic prompts, product info, or policy guidance instantly
• Escalation Trigger Detection: Flag certain keywords or sentiment shifts in real time
• Compliance Monitoring: Catch script deviations or risky language before it becomes a problem

With Real-Time Transcription, your contact center becomes more proactive, agile, and more responsive to the needs of your customers and your agents.

What is Post-Call Transcription?

Post-Call Transcription delivers a complete transcript after the call ends.

The Post-Call transcript is typically more formatted than its RTT counterpart, and reflects better accuracy due to the presence of full audio context. That accuracy and formatting allows post-call transcripts to better integrate with other business applications, like the ElevateAI Generative AI-powered feature suite.

Why Use Post-Call Transcription?

• QA Review and Coaching: Score calls and give agents actionable feedback
• Voice Data for AI Models: Feed labeled conversations into your training workflows
• Sentiment and Intent Analysis: Run detailed analytics to understand how customers feel and what they need

Post-Call Transcription turns every conversation into a data source you can analyze, optimize, and ultimately, to act on.

Real-Time vs. Post-Call Transcription: Which Should You Use?

Here’s the trick: you don’t have to choose.

Each approach serves a different moment in the customer journey – and just like peanut butter and jelly, they’re even better together.

• Use Real-Time to guide the conversation.
• Use Post-Call to learn from it.

And the smartest CX teams do both.
