Lectures in a Second Language: Transcripts and Terms

Why lectures are harder than everyday conversation

Many students who manage well in shops, flatshares and social life still find lectures exhausting. The reasons are specific, which means they can be tackled one by one.

You can't interrupt. In conversation you can ask someone to repeat themselves; in a hall of two hundred, you rarely can.
Academic register uses longer sentences, more abstract nouns and careful hedging.
Each discipline has its own terms, and everyday words take on narrow meanings: significant in statistics, stress in engineering, culture in microbiology.
Lecturers vary in speed and accent, and the accent you learned may not be the one you hear at the front of the room.
You are listening, reading slides and writing notes at the same time, all in your second language, which divides attention more than it does for native speakers.
Jokes, asides and references to local institutions assume background you may not have.

It is common for the first weeks of a course to be the hardest, with comprehension improving as you learn your field's vocabulary and your lecturers' speaking habits. The workflow below speeds that up.

Before the lecture: build the terminology list

Most of a lecture's difficult vocabulary is predictable. It is in the reading list, the slides if they are posted in advance, the textbook glossary and last year's materials. Fifteen minutes with those before class turns many unknown terms into recognized ones.

Keep one running list per course with these columns:

Term: Written exactly as the course uses it, including abbreviations.
Definition: In the language of instruction, using the course's own definition rather than a general dictionary's.
First-language equivalent: Your own language's term, so you can connect it to what you already know.
How it sounds: Stress, a pronunciation note, or how an acronym is spoken.
Source: The slide, reading or lecture timestamp where you met it.

The pronunciation column matters more than most students expect. You may know a term perfectly from reading and still not recognize it spoken, because the stress falls somewhere unexpected or because an acronym is said as a word rather than as letters. Hearing a term once in the recording and noting how it sounds closes that gap.

Recording the lecture: ask first

Recording is a permission question before it is a technical one. Check your institution's policy, ask the lecturer, and remember that many universities already record lectures through a lecture capture system, though downloading those recordings may or may not be allowed. Some students arrange recording through a disability or student support office. The full discussion of permission, sharing and recording laws is in AI transcription for students, so it is not repeated here.

After the lecture: transcript first, translation only where you got lost

The transcript lets you revisit the lecture at reading speed, which is often much easier than listening speed in a second language. The translation is a tool for the hardest passages, not a replacement for the original.

During the lecture, write the clock time in your notes whenever you lose the thread. If the lecture started at 10:05, a note saying 10:32 points to minute 27 of the recording.
Afterward, read the original transcript at those points first. Often the problem was one word you didn't catch, and the text shows it immediately.
If a passage is still unclear, read the translated transcript for those lines, then go back to the original and find the words that carried the meaning. Add new terms to your list.
Use the original transcript to get spellings of terms you heard but couldn't write down, so you can look them up in the textbook.
Don't study from the translation. Machine translation can render technical terms inconsistently or wrongly; see translating technical terms for why.

Turning the corrected understanding into structured notes is a separate step, covered in lecture video to study notes.

Listening for the lecture's signposts

Lecturers mark the structure of a talk with recurring phrases. Recognizing them gives you a map of the lecture even when the details escape you, and searching the transcript for them is a quick way to find where each section begins. In English, for example:

Sequence: first of all, the second point, moving on to.
Emphasis: the key thing here is, this will come up again, make sure you understand.
Contrast: however, on the other hand, whereas.
Example: for instance, take the case of, imagine that.
Hedging: it seems that, arguably, there is some evidence that. These matter, because they tell you how strongly to state the claim in your own work.
Digression and return: as an aside, anyway, back to.
Summary: so, to sum up, the main takeaway is.

Every language of instruction has its own set. Collecting your lecturers' versions, with a timestamp for each, is one of the most useful short lists you can build in your first month.

A fluid mechanics lecture in German

Suppose an engineering student from Vietnam is in her first semester at a German university. Before a 90-minute fluid mechanics lecture, she adds twelve terms from the posted slides to her list, including Druckverlust (pressure loss) and Reynolds-Zahl. During the lecture she writes down the clock time three times when she loses track. Afterward she transcribes the recording with a Vietnamese translated transcript for 90 credits (9¢). At the first marked point, the German transcript alone shows she had missed Reynolds-Zahl because she had only ever read it, never heard it. At the second and third, she needs the Vietnamese lines to follow a derivation, then returns to the German to note the phrasing.

The whole follow-up took about 40 minutes, not a second viewing of 90. She read three passages closely instead of rewatching everything, added nine terms with pronunciation notes, and learned one signpost phrase her lecturer used before every key equation.

A weekly routine for one demanding course

Before each lecture, skim the slides and readings and update the terminology list.
During the lecture, keep notes brief and write the clock time when you get lost.
On the same day, transcribe the recording, adding a translated transcript if you want one.
Read the original transcript at each marked point; use the translation only where the original still doesn't make sense.
Relisten to just those minutes of audio to connect the text to the sound.
Once a week, read the term list aloud, so you can say the words in seminars as well as recognize them.
Before a seminar or office hours, prepare one question that uses the new terms.

Start with the one course you find hardest. Doing this for every course at once is more than most students can sustain.

Trade-offs and limits to keep in mind

Time. Reviewing transcripts adds work each week, so prioritize the courses where you lose the most.
Dependence. A transcript safety net can make it tempting to stop listening hard in class. Treat the live lecture as the main event and the transcript as backup, and aim to need it less as the term goes on.
Equations and code. Spoken mathematics comes out as words, such as "x squared over two", so take notation from the slides.
No speaker labels. Student questions and the lecturer's answers run together in the transcript.
Accents. Recognition can be weaker for some accents, much as your own listening is; speech recognition and accents explains why.
Mixed languages. Lecturers in many countries drop English technical terms into lectures in another language, and the spoken language is detected automatically, so such passages can come out inconsistently.
Recording isn't always allowed, especially in small seminars where people share personal views.
Universities usually have academic language support, such as language centers and writing centers. Transcripts complement that support rather than replacing it.

How mydubly helps with second-language lectures

mydubly works on lecture recordings you already have on your device, either video (MP4, MOV, WebM, MKV, M4V) or audio (MP3, WAV, M4A, AAC, OGG, FLAC), up to 2 hours per file. Transcript mode returns a plain transcript, a timestamped transcript and SRT and VTT subtitles in the lecture's language, which is detected automatically, plus an optional translated transcript in another of the 21 supported languages. It costs 1 credit per minute with a 5-credit minimum per file, so a 90-minute lecture costs 90 credits (9¢).

The video file stays on your device; only compressed audio is uploaded, and it is deleted within 30 minutes of the job finishing. mydubly can't fetch recordings from a lecture-capture link, and it works on finished files, so it offers no live help during the lecture itself. Slides and anything written on the board are not translated, because only speech is processed. The video to text page lists formats and languages, and the lecture translation page covers translating whole lectures.

Start with this week's hardest lecture

Pick the lecture where you got lost most often, build a short term list from its slides, and transcribe the recording with video to text. Work only through the passages you marked. After three weeks, compare how many times you write a clock time in your notes; that number is a practical measure of progress.

Frequently asked questions

Will relying on transcripts slow down my listening progress?

It can, if the transcript replaces listening rather than supporting it. Keep listening hard in the lecture, use the transcript only for the moments you marked, and relisten to those minutes after reading them. Many students find they need the transcript less each month as their field vocabulary grows, which is the outcome to aim for.

Should I take notes in my first language or the language of instruction?

Mixing is common and often practical: quick notes in whatever language is fastest for you, with key terms always written in the language of instruction. Exams, essays and seminars will use those terms, so writing them in the original from the start saves you translating back later.

Can I get the lecture slides translated as well?

Not with mydubly, which processes speech only and does not translate slides, documents or text in the picture. Use a document translation tool for slide files if your course allows it, and check terms against the course's own definitions. Translating on-screen text in videos covers options for text that appears in recordings.

What if my lecturer has an accent I find hard to follow?

Exposure helps more than anything: recordings of that lecturer, listened to repeatedly, train your ear to their particular sounds. Reading the transcript while relistening to a few minutes speeds this up. If recognition also struggles with the accent, check doubtful lines against the slides, and consider asking the lecturer whether written notes are available.

Can I use a translated transcript when writing an assignment?

Use it to understand the material, then write in your own words in the language of the assignment. Copying translated lecture text into submitted work is plagiarism, and quoting the lecturer needs a citation from the original wording. Course policies on translation and AI tools differ, so check yours before relying on them.
