FAQ
Frequently asked questions
Answers to the most common questions. Anything else, just ask via support.
What audio formats does ListenSlice support?
ListenSlice supports all major audio formats including MP3, WAV, M4A, AAC, OGG, and more. You can directly upload podcasts, audiobooks, YouTube audio, or any audio files containing English speech.
How long does audio processing take?
Processing time depends on your audio length and device performance. Typically, a 10-minute audio file takes 1-2 minutes to process. All processing happens locally in your browser, protecting your privacy without server wait times.
Are there any limitations in the free version?
The free version can process audio files up to 15 minutes long, with a limit of 3 files per month. Upgrading to Pro removes these restrictions, supporting unlimited audio length and processing frequency.
What device and browser requirements are needed?
ListenSlice requires a modern browser with WebGPU support. We recommend using the latest versions of Chrome, Edge, or Firefox. For optimal performance, use a device with a dedicated GPU. Mobile devices are supported but may process slower.
How do I practice dictation with ListenSlice?
Upload your audio, switch to Dictation mode, and work through it sentence by sentence: listen (replay as many times as you need), type what you hear, then hit Check. You'll see a word-by-word comparison and an accuracy score, so you know exactly which words you're missing. 20-30 minutes daily is the fastest way to improve listening.
What kind of audio is best for improving English listening?
You can upload any audio! Podcasts, audiobooks, TED talks, and news are great for focused practice. ListenSlice supports MP3, WAV, M4A, and more, making it easy to transform your favorite content into learning material.
Is this AI audio slicer free for language learners?
Yes! The free version allows language learners to process 3 audio files per month, up to 15 minutes each. Dictation mode and sentence-by-sentence playback are included for free — perfect for trying the intensive listening method.
Can I use ListenSlice for IELTS or TOEFL listening practice?
Absolutely — that's what it's built for. Upload your own practice test audio (e.g. Cambridge IELTS recordings you own), and ListenSlice slices it into sentences for dictation drills. Since files are processed locally in your browser and never uploaded, practicing with your own copyrighted materials is completely private.
Is my privacy protected while I practice English?
Yes, 100%. All AI processing (WebGPU + Whisper) happens locally in your browser. Your audio never leaves your device. We prioritize your privacy so you can focus on learning how to improve English listening skills without worry.
How accurate is the AI transcription for different accents?
ListenSlice uses the advanced Whisper AI model, providing over 95% accuracy for various English accents (US, UK, Australia, etc.). It's a highly reliable way to improve your comprehension of diverse speech patterns.
