How to Build a Personal Vocabulary Dictionary from Video Transcripts

Generic vocabulary lists are easy to find and hard to remember, because the words come with no story. Words you meet in a video you chose — said by a real person, about something you care about — are far more memorable. The problem is keeping track of them. This guide shows how to build a personal vocabulary dictionary from video transcripts, and how to review it so the words become part of your active vocabulary.

What makes a good personal dictionary

A useful entry contains more than a translation:

The example sentence is the most important part. It shows grammar, typical word partners and tone in a way a definition can't.

Step 1: Save the transcript as a book

1. Extract the video's transcript on the Transcriptly home page in original-language mode.
2. Click Save to My Library. You'll need a free account — that's where your word list is stored.
3. Open the book from your library.

Step 2: Look up words while you read

In the reader, select or tap an English word. A popup shows:

• a definition (from open sources such as Wiktionary),
• pronunciation, shown in IPA where available,
• a Bangla meaning,
• a dictionary example sentence where one is available.

Lookups don't add anything to your list. Read normally and look things up freely; you choose what to save in the next step.

Step 3: Save selectively

Click save on the popup to add the word to your dictionary. Transcriptly records which book the word came from, and each saved word links back to that book, so you can always return to the original context. The example sentence in the popup comes from the dictionary, not from your video — so if the video's sentence is a better example, copy it into the word's note (next step).

Not every unknown word deserves saving. A practical filter:

• Save words you've seen more than once, words you'd like to use yourself, and phrases whose meaning isn't obvious from their parts.
• Skip names, very rare technical terms outside your field, and words you understood easily from context and won't need.

Five to ten words from a ten-minute video is plenty. You can always come back for more.

Step 4: Add your own note

The dictionary page lets you add notes to each saved word. Start by pasting the sentence from the video where you met the word. Then add notes about how the word is used:

• Collocations: "make a decision" not "do a decision".
• Register: formal, informal, slang.
• Contrast: "nuance vs difference — nuance is subtle".
• A sentence of your own using the word.

Writing your own sentence is one of the most effective ways to move a word from recognition to use.

Step 5: Review with spacing

Words are forgotten quickly unless they're reviewed. The dictionary page has a Review Flashcards mode that shows saved words for you to recall, and lets you set each word's status:

• New — not yet studied.
• Learning — you recognise it but aren't confident. Words you save from the reader start here.
• Learned — you can recall its meaning and use it.

A simple routine:

1. Review newly saved words the next day.
2. Review "learning" words every few days.
3. Review "learned" words occasionally — once a week or two — to make sure they stay learned.
4. When you review, try to recall the meaning before revealing it, and say an example sentence aloud.

Filter by status to focus a session — for example, only the words you're still learning — or search your list for a specific word.

Step 6: Meet the words again

Words stick when you meet them in new contexts. After a week or two:

• Rewatch the original video without captions and listen for your saved words.
• Watch a different video on the same topic — topic-specific vocabulary repeats.
• Use the words in writing: a short summary of the video is ideal practice.

Organising a large dictionary

As your list grows:

• Use the source links. Each word links to the book it came from — handy for revisiting all the vocabulary from one documentary before you rewatch it.
• Prune. If a word has been "learned" for months and you use it confidently, it doesn't need regular review.
• Group by theme in your notes — "words for describing change", "academic verbs" — to see patterns.

Example: one video, one session

Say you watch a ten-minute documentary segment on ocean currents. In the transcript you look up fourteen words and save six: circulation, density, upwelling, sink, nutrient-rich and drive. For drive, you paste the video's sentence into the note and add: "here means to cause or power, e.g. wind drives the current". The next day you review the six, and three days later you watch a different ocean video — and recognise four of them without thinking.

Common mistakes

• Saving translations without context. A list of word–translation pairs is the least memorable kind of list.
• Saving too much. Long, unreviewed lists create guilt, not vocabulary.
• Never reviewing. Saving a word is the first step, not the last.
• Only recognising, never producing. Write and say your own sentences.

Frequently asked questions

Do I need an account for the dictionary?

Yes. The word list is stored in your account so it's available on any device. Reading and extracting transcripts doesn't require an account.

Can I look up phrases, not just words?

The lookup is designed for single words (including hyphenated words and words with apostrophes). For phrases, save the key word and write the full phrase in the note.

Does it support translations into languages other than Bangla?

Currently, the word popup shows Bangla meanings for English words. Full transcripts can be translated into other languages with the translation mode on the home page.
