Frequently Asked Questions

How accurate is free speech to text conversion?
OpenAI Whisper achieves a 4.2% word error rate on standard benchmarks, which is comparable to professional human transcribers. On clear speech, accuracy exceeds 95% for English and most major languages. Selecting a larger model (Small or Medium) further improves results on accented or noisy audio.
Is this speech to text tool really free?
Yes — local mode is completely free with no account required. Unlike TurboScribe (3 free transcriptions/day) or Otter.ai ($16.99/month after 300 minutes), Whisper Web runs the AI entirely on your device with zero server costs and no usage limits.
Can I use my microphone for speech to text online?
Yes. Click the microphone button to record directly in your browser. Your browser will request microphone permission once. Recording supports clips up to 60 seconds, with transcription starting automatically when you stop. Ideal for dictation, note-taking, and quick voice memos.
Does speech to text work offline without internet?
Yes. After the initial Whisper model download (~40 MB for Base, ~150 MB for Small), speech to text runs fully offline. The model is cached in your browser, so subsequent visits work without any internet connection — unlike cloud services that require constant connectivity.
Is my speech data private and secure?
All processing happens locally in your browser via WebGPU or WebAssembly. Zero audio is uploaded, stored, or transmitted to any server. This makes Whisper Web suitable for confidential content: medical dictation, legal recordings, private meetings, and HIPAA-sensitive workflows.
What languages does the free speech recognition support?
Whisper supports 100+ languages, including English, Spanish, Mandarin, French, German, Japanese, Korean, Arabic, Hindi, and Portuguese. Automatic language detection identifies the spoken language, or you can manually select it for optimal accuracy.
