DET Interactive Listening: Listen and Complete, Listen and Respond and Summarize the Conversation

Interactive Listening puts you inside a short university conversation on the Duolingo English Test (DET). You listen to a scenario (the background to the situation), complete three or four sentences about it, then take part in the conversation by choosing your replies, and finally write a short summary. One conversation in every test is between two students, another between a student and a professor, on everyday university topics: asking for help or advice, planning study, asking for information, making requests.

The three parts and their timing

Part	What you do	Number	Time	Scoring
Listen and Complete	listen to the scenario; type the missing part of 3–4 sentences about it	3–4 per scenario	shared 6 min 30 s	partial credit: meaning counts, spelling does not
Listen and Respond	hear the other person; choose the best reply from options	5–6 per scenario	(same 6 min 30 s)	right or wrong for each turn
Summarize the Conversation	write a summary of the conversation	1 per scenario	75 seconds	writing criteria: content, coherence, grammar, lexis

The first two parts share one timer of 6 minutes 30 seconds; the summary has its own 75 seconds. Expect two scenarios (Duolingo’s 2026 guide says two or three). Listen and Complete and Listen and Respond count toward Listening. The summary counts toward Writing, and its content also counts toward Listening, because it shows whether you understood.

Since July 2025 the scenario is heard, not read, and you can replay it as many times as you like, even during Listen and Respond (scroll up). The timer keeps running while you replay. Each line from the other speaker in Listen and Respond plays only once.

Part 1: Listen and Complete

You hear something like this scenario:

You are a first-year student. You missed last Thursday’s statistics lecture because you were sick, and the assignment based on it is due on Monday. You decide to visit Professor Lee during her office hours to ask what you should do.

Then you complete sentences:

The student missed the lecture because ________.
The assignment is due ________.
The student goes to see the professor during ________.

Good answers: they were sick / on Monday / her office hours.

Rules that help, from Duolingo’s help center:

Paraphrasing is fine, and some questions need it. he was ill is as good as they were sick.
Minor spelling, punctuation and grammar errors do not matter if the meaning is right.
Write just enough. Too much or too little lowers the score. on Monday is right; on Monday, which is in four days, so the student is worried is too much.

Most students spend less time here than on Listen and Respond. Aim for about a minute.

Part 2: Listen and Respond

Now you are in the conversation. Sometimes you speak first and must choose how to start; sometimes you listen first. A worked turn:

Professor Lee: Hi, come in. What can I do for you?

A. Hey! What’s up? I need the lecture stuff.
B. Hello, Professor Lee. I’m in your Thursday statistics class. I missed last week’s lecture because I was sick, and I wanted to ask how to catch up.
C. Hello. I would like to know about the history of statistics.
D. Hello, Professor Lee. I’m in your Thursday class. I need an extension on the assignment until next month.

Answer: B. A is too informal for a professor. C ignores the scenario. D asks for something the scenario never mentioned and adds information. Duolingo lists exactly these reasons for wrong options: they do not fit the scenario, do not match what the other person said, use the wrong words or pronouns, are too formal or informal, or add or leave out information.

Professor Lee: I’m sorry to hear that. The slides are online, but the assignment uses a method I only explained in class.

A. Then could you recommend a chapter or a classmate’s notes I could use?
B. Great, so I don’t need to do the assignment.
C. The slides are not online, I checked.
D. I’m feeling much better, thank you.

Answer: A. It responds to the problem she just raised. B misunderstands; C contradicts her; D answers a question nobody asked.

After each choice you see a green tick or a red cross. If you were wrong, read the correct answer: the conversation continues from it, and it tells you what comes next.

Part 3: Summarize the Conversation

You have 75 seconds. Write in full sentences, not bullet points, in the first person (I…) or the third person (A student…). Cover the situation, the main points and how it ended. Using words from the conversation is allowed.

A model summary (about 60 words) for the conversation above, assuming the professor suggested a chapter and offered a short meeting:

A student who missed a statistics lecture because of illness visits Professor Lee to ask how to catch up before Monday’s assignment. The professor explains that the slides are online but do not include the method used in the assignment. She recommends reading chapter four and offers a short meeting on Friday to answer questions, and the student agrees.

Why it works: it says who and why (situation), what the problem was (main point), and what happened at the end (outcome), with linking words (but, and) and no list formatting.

A practical template you can adapt: [Who] talks to [whom] about [problem]. [Person] explains/suggests [main point]. In the end, [outcome].

How to use the 6 minutes 30 seconds

Listen to the scenario once, fully. Then answer Listen and Complete; replay only for a missing detail.
In Listen and Respond, read all options before choosing. Check tone, the speaker’s last words and the scenario.
Save 30–60 seconds at the end to read back through the conversation on screen. That is your summary plan.

Common mistakes

Choosing the most “polite” option automatically. Overly formal replies to a classmate can be wrong too. Match the relationship.
Choosing a reply that adds new facts. If the scenario did not mention an extension, the right answer will not ask for one.
Writing a whole paragraph in Listen and Complete. Short, exact phrases score best.
Writing the summary as notes. Bullet points and fragments lose coherence and grammar points.
Forgetting the ending. A summary that stops at the problem misses the outcome.

How to improve

Listen to real university situations: office-hour role-plays, student podcasts, advice videos. Notice how students ask for things politely.
Learn request and response phrases: I was wondering if…, Would it be possible to…, That makes sense, Could you clarify…
Practice 75-second summaries of any short conversation you hear, typed, with a timer.

The typing speed you build in Listen and Type helps here, and the summary is one of the writing tasks described in DET writing tasks.

Practice Interactive Listening in the Nomto room

The Interactive Listening drill in the Nomto DET room plays an original scenario, then runs all three parts with the shared 6:30 timer and a separate 75-second summary. Your choices are marked at once, and the summary gets a review with corrections and a model version. A free account includes 10 reading and listening items and 1 written answer reviewed by AI.

Common questions

How many times can I listen to the scenario? As many times as you want, but the timer keeps running.

Can I replay what the other speaker says in Listen and Respond? No. Each line plays only once.

Does spelling matter in Listen and Complete? No, as long as the meaning is right.

How long should my summary be? There is no word count. In 75 seconds, three or four full sentences that cover situation, main points and outcome are realistic.
