How to Practice Describing Real-World Images for Duolingo

 The Duolingo English Test (DET) has emerged as a widely accepted and convenient alternative to traditional English proficiency exams like IELTS and TOEFL. One of the most unique and challenging components of the DET is the “Speaking Sample” task, which frequently requires test-takers to describe real-world images in a coherent, fluent, and grammatically accurate manner.

Understanding how to prepare effectively for this task is crucial for scoring high in the speaking section. In this guide, we’ll explore the best ways to practice describing real-world images, backed by research-based strategies, scoring tips, and linguistic techniques. Whether you're aiming for university admission, immigration, or employment, mastering this skill can significantly enhance your performance.




Understanding the Task: Describe an Image

In the Duolingo English Test, candidates are often shown a photograph or illustration and asked to speak about it for 30–90 seconds. This exercise assesses the test-taker’s ability to:

  • Interpret visual information

  • Organize and articulate thoughts

  • Demonstrate vocabulary range

  • Maintain grammatical accuracy

  • Display fluency and pronunciation

The images may depict everyday situations, urban or rural scenes, public transportation, markets, classrooms, or social interactions.


Why This Task Matters: Scoring Insights

Duolingo uses automated AI-based scoring, which evaluates responses across various linguistic parameters. For the image description task, the AI primarily assesses:

Criterion

What It Measures

Fluency

Speech continuity and pace

Vocabulary

Word variety and appropriateness

Grammar

Sentence structure, tenses, articles, and prepositions

Pronunciation

Clarity, stress, and intonation

Coherence

Logical organization and transition between ideas

Content Relevance

Relevance of speech to the given image

According to data from Duolingo, test-takers who speak continuously for at least 60 seconds and use diverse vocabulary score significantly higher—often in the 115+ band.


Step-by-Step Approach to Practicing Image Description

1. Start With Observation

Before speaking, train yourself to observe an image critically. Note key elements such as:

  • People and their actions

  • Objects in the foreground/background

  • Mood or tone (e.g., chaotic, peaceful)

  • Environment or setting (urban, rural, indoor, outdoor)

  • Colors, weather, and time of day

Tip: Take 5–10 seconds to scan the image and mentally structure your response.


2. Use the “What, Where, Who, and Why” Framework

Organize your description using these questions:

  • What is happening in the image?

  • Where is the scene taking place?

  • Who are the people involved?

  • Why might the event be occurring?

Example:
"The image shows a group of students sitting in a classroom. It appears to be a high school setting, and the teacher is pointing to a whiteboard. The students look engaged, possibly attending a science lecture."

This approach ensures that your speech is structured and contextually rich.


3. Build Vocabulary Bank by Category

Create word banks under these themes:

  • People: elderly, toddler, adolescent, vendor, customer

  • Places: sidewalk, intersection, cafeteria, lecture hall

  • Activities: conversing, gesturing, observing, participating

  • Emotions: delighted, anxious, curious, focused

  • Objects: whiteboard, stethoscope, briefcase, billboard

According to lexical density research, responses with 30%+ high-level vocabulary are likely to receive a C1 (Advanced) or higher proficiency band.


4. Practice with a Timer and Recorder

Simulate the test conditions:

  • Set a 60–90 second timer

  • Record your responses

  • Replay and analyze: Did you hesitate? Did you repeat words? Was your speech logical?

Fact: According to fluency benchmarks, a speech rate of 100–130 words per minute is optimal for clarity and coherence.


5. Apply Descriptive Language and Transitions

Your goal is to sound natural, not robotic. Use:

  • Adjectives and adverbs: vibrant market, gently walking, densely populated

  • Connectors: Firstly, in addition, meanwhile, as a result, on the contrary

Example:
"Firstly, I notice a group of teenagers playing basketball. They seem to be enjoying themselves under the afternoon sun. In the background, a man is jogging, possibly exercising after work. Overall, the scene portrays a lively park setting."


6. Avoid Common Mistakes

Here are pitfalls to watch for:

Mistake

Correction Strategy

Repeating simple words

Use synonyms or paraphrasing

Speaking too fast or slow

Practice pacing and breathing techniques

Pausing too often

Use filler phrases like “It seems that…” or “I would say…”

Going off-topic

Stay visually grounded in the image context

Grammar mix-ups

Revise tenses, articles, and plural forms regularly


7. Leverage AI-Powered Mock Tests

Practicing in a test-like environment with automated scoring and feedback is critical to improvement. It replicates pressure conditions and helps you:

  • Identify weak areas

  • Track fluency and grammar accuracy

  • Improve pronunciation with AI analysis

  • Gain confidence through real-time evaluation


Additional Tips to Score High in the DET Speaking Section

  • Warm Up with Simple Descriptions: Use everyday photos to describe settings aloud.

  • Use Shadowing Technique: Listen to native speakers describe images and mimic their tone and rhythm.

  • Join Online Speaking Forums or Practice Groups: Peer feedback is invaluable.

  • Review High-Scoring Sample Answers: Analyze what makes them effective.

  • Keep an Image Journal: Describe one image daily and record it for self-review.


Use Official Resources—But Don’t Stop There

While Duolingo provides sample questions, consistent practice across multiple image types is essential. Diversify your sources:

  • Use news photos, travel websites, or real-life images

  • Practice with random scenes from public photo galleries

  • Simulate unpredictable image types to build adaptability
