TL;DR
Last updated: April 2025
An audio to quiz generator is an AI tool that listens to a spoken audio recording, transcribes what was said, and automatically creates multiple-choice quiz questions from the content. Instead of replaying a lecture recording multiple times and writing your own test questions, you upload the audio file and receive a ready-to-take quiz in under a minute.
Shinyu.ai's free audio quiz generator is built for students who record lectures on their phone, download podcast episodes for study, or receive audio course material. Upload any clear spoken audio and the AI identifies the key topics, facts, and concepts discussed — then builds targeted multiple-choice questions that test genuine comprehension of the recording.
The quiz generator works best with clear spoken audio where the speech is the main content. Educational recordings with distinct topics, definitions, and explanations produce the most accurate quiz questions.

Many students record lectures on their phone or laptop — but replaying a recording passively is one of the least effective revision strategies. You hear the same information again without actually testing whether you retained it. Research by Roediger & Karpicke (2006) found that active recall — testing yourself with questions — produced 50% better long-term retention compared to passive re-listening or re-reading.

MP3, WAV, M4A, OGG, FLAC, and AAC are all supported. MP3 and M4A are the most common formats for lecture recordings and podcast downloads. Files up to 50MB are accepted on the free plan, which covers most recordings up to 45-60 minutes.
The AI first transcribes the spoken content of your recording using speech recognition, then analyses the transcript to identify key facts, definitions, and concepts. It then creates multiple-choice questions with plausible distractors — wrong answers that are similar enough to the correct answer to genuinely test your knowledge.
The free tool supports audio files up to 50MB, which covers recordings of approximately 45-60 minutes in standard MP3 format. For longer recordings, try splitting the audio or sign up for a Shinyu.ai account which supports larger files.
Accuracy is highest for clear speech recorded in a quiet environment with minimal background noise. Lecture recordings made from a phone or laptop in a classroom work well. Heavy accents, overlapping speakers, or poor microphone quality will reduce transcription accuracy and may affect question quality.
Yes — educational podcast episodes work well as a quiz source. Download the episode as an MP3, upload it here, and the AI generates questions from the spoken content. Best results come from interview-style or documentary podcasts with clear factual content.
The YouTube to Quiz tool works with any public YouTube URL — no file download needed. The Audio to Quiz tool works with locally saved audio files in MP3, WAV, M4A, and other formats. Use YouTube to Quiz for online video content and Audio to Quiz for recorded lectures, downloaded podcasts, or voice memos.
Gemini AI supports transcription in 50+ languages including English, Hindi, Spanish, French, German, Mandarin, and many more. Quiz questions are generated in the same language as the spoken content in your recording.
