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.
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.
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.
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.
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.
