How to Prepare for the PTE Academic Speaking Section: Describe Image and Retell Lecture

Why These Two Tasks Trip People Up

Let's be honest — the PTE Academic speaking section can feel like a sprint. You're staring at a complicated graph or listening to a fast-paced lecture, and you have just seconds to organize your thoughts before speaking.

The good news? Describe Image and Retell Lecture aren't about creativity. They're about structure. Master the structure, and your fluency and pronunciation scores will follow.

Here's how to prepare for both — no fluff, just what actually works.

Describe Image: The 4-Step Formula

Most test-takers panic when they see a bar chart or process diagram. They try to describe everything at once, stumble, and lose points on fluency.

Stop doing that.

The trick is to use a fixed template. Not a rigid one-size-fits-all script, but a flexible framework that works for any image type.

Step 1: The 2-Second Overview

Start with one simple sentence that tells the examiner what the image is about.

• "This graph shows the number of tourists visiting Australia from 2010 to 2020."
• "The diagram illustrates the process of recycling plastic bottles."

That's it. No extra details yet.

Step 2: Pick 2-3 Key Points

You don't have time to mention every data point. Pick the most obvious trends or features:

• Highest and lowest values
• Major increases or decreases
• The beginning and end of a process

Keep your language simple: "The highest point was…", "There was a sharp rise in…", "This is followed by…"

Step 3: A One-Sentence Conclusion

Wrap up by stating the overall trend or purpose.

• "Overall, the number of visitors increased significantly over the decade."
• "In summary, the recycling process involves five main stages."

Step 4: Speculate (Optional but Powerful)

If you have time, add a quick prediction or reason.

• "This increase might be due to cheaper flights."
• "This process helps reduce waste."

Here's how that flow looks visually:

Practice this flow until it feels automatic. When you're in the exam, you won't have time to think about what to say. You'll just fill in the blanks.

Retell Lecture: The Note-Taking Framework

Retell Lecture is harder for most people. You can't see anything — you just hear a 60-90 second recording, and then you have to summarize it.

The biggest mistake? Trying to write down every word. You can't. The recording is too fast, and your handwriting is too slow.

Instead, use a simple note-taking system. Here's what to jot down:

• Topic — What is the lecture about? (e.g., "climate change effects on agriculture")
• Purpose — Is the speaker explaining, arguing, or describing? (e.g., "argues that rising temperatures reduce crop yields")
• Key Points — 2-3 main ideas the speaker emphasizes (e.g., "rice production down 10%", "droughts in India", "new drought-resistant crops")
• Example or data point — One specific detail if you catch it
• Conclusion — How does the speaker end? (e.g., "concludes that adaptation is urgent")

When it's your turn to speak, use your notes to rebuild the lecture in your own words.

A strong retell sounds like this:

"The lecture was about the impact of climate change on global agriculture. The speaker argued that rising temperatures are already reducing crop yields, especially rice production in Asia. They mentioned droughts in India as a key example. The speaker concluded that investing in adaptation is urgent."

Notice the structure: topic → purpose → key points → example → conclusion.

That's your retell template. Memorize it.

Practice Smart, Not Hard

Here are three practical exercises that will improve your score faster than any generic PTE Academic speaking tips you'll find online:

1. Voice record yourself daily. Use your phone. Pick a random graph or a YouTube short lecture (2-3 minutes). Describe it or retell it. Listen back. You'll immediately notice where you hesitate or mumble.

2. Master your transition words. Words like "firstly," "in addition," "however," and "as a result" help you sound fluent and organized. Practice using them without thinking.

3. Focus on pronunciation, not accent. Clear pronunciation matters. Accent doesn't. Don't try to sound British or American. Speak clearly at a natural pace.

The Bottom Line

Describe Image and Retell Lecture are intimidating, but they follow predictable patterns. Learn the pattern, practice it until it's automatic, and you'll walk into that exam room with confidence.

Don't memorize every word. Memorize the structure.
