Practice English with podcasts — transcript included
Podcasts are perfect listening material with one flaw: no answer key. The AI transcript fixes that.
Teachers have recommended podcasts to English learners for years, and for good reason: real vocabulary, real speech rhythm, topics you actually care about. But without a transcript you can never verify what you heard — you finish an episode with a comfortable illusion of understanding and no idea what you missed.
ListenSlice turns any podcast episode you have into verified practice. The AI transcribes it in your browser, slices it into sentences, and lets you check yourself against the transcript sentence by sentence — listen mode for shadowing along, dictation mode for proving you caught every word.

How it works
01Get the episode file
Download from the podcast’s own site or app export — you practice with your copy.
02Drop it in
The AI transcribes locally; a 10-minute chunk is ready in about a minute.
03Verify your listening
Dictate the sentences you are unsure of; the transcript is the answer key.
From an episode to a session
A 40-minute episode is not a practice session — it is a content library. Work through a section at a time: play straight through once, flag the sentences that lost you, then drill only those. Ten focused minutes on eight hard sentences beats an hour of passive listening.
Unknown words keep their context
Tap any word in a sentence to see its definition and translation, and save it to a word notebook — with the sentence audio it came from. Reviewing words later replays the exact podcast sentence, so the word stays anchored to real speech instead of a flashcard.
Frequently asked questions
Where do I get podcast audio files?
Most podcasts publish direct MP3 downloads on their episode pages or in their RSS feed, and many podcast apps have an export or show-file option. Practice with your own downloaded copy.
How accurate is the AI transcript for fast conversational speech?
Whisper handles natural conversation well, including fillers and false starts. Heavy crosstalk or poor recording quality lowers accuracy — news-style and interview podcasts work best.
Which podcasts are good for English learners?
Interview shows with clear hosts are ideal at intermediate level; narrative journalism suits advanced learners. The built-in library also includes NASA’s interview podcasts — real professional conversation, free and unlimited.
Can I practice without downloading anything?
Yes — the free library has 600+ episodes including natural-speed NASA conversations that are the closest thing to podcast English, ready with one click.
