FAQ
Answers to the most common questions. Anything else, just ask via support.
You listen once and answer questions in recording order. Instead of returning only a total, ListenSlice maps each answer to a listening process such as speech decoding, exact-detail recognition, paraphrase mapping, distractor control, retention, or question tracking, then opens a targeted practice prescription. The current short baseline gives a direction, not an official IELTS band score.
Nothing is uploaded by default. Transcription (Whisper, via WebGPU) runs entirely in your browser, so your audio never leaves your device — that's what makes it safe to practice with materials you own. The only exception is optional cross-device sync of your progress and notebook (never the audio itself), and an opt-in Pro audio backup you turn on yourself.
The 769 free library episodes open instantly — they come pre-sliced, so you start practicing with zero wait. When you upload your own file, Whisper transcribes it in your browser first; a 10-minute file typically takes a minute or two, one time, then it's saved for instant resume.
Free covers the whole 769-episode library (unlimited), 3 of your own uploads a month up to 15 minutes each, dictation scoring, sentence playback, and a few daily AI-tutor questions. Pro ($4.99/mo or $39 lifetime) unlocks unlimited uploads and length, pitch-preserved speed control, the full daily AI-tutor allowance, subtitle/transcript export, and audio backup.
Yes. Every sentence has a built-in AI tutor, right in the practice canvas — ask why you couldn't catch a phrase, how the grammar works, or what an expression means, and get a compact, listening-focused answer in your own language. It's a multi-turn chat, so you can keep following up. Free accounts get a few questions a day; Pro unlocks the full daily allowance.
Your own MP3, WAV, M4A, AAC, or OGG files — practice tests, podcasts, lectures, audiobooks — plus a free library of 769 graded episodes: slow VOA news, natural-speed audiobooks and full-cast drama, NASA conversations, and human-narrated Wikipedia articles, sorted by CEFR level (A2–C1).
ListenSlice uses Whisper large-v3, which handles US, UK, Australian and other English accents well. Library episodes are transcribed and sentence-aligned ahead of time for clean playback boundaries; and since you're checking your own typing against the reference, you're learning from the audio itself, not depending on a perfect transcript.
