FAQ

What is Speech to Text?

Speech to Text converts spoken audio to written text using the Web Speech API. Input: microphone audio (real-time). Output: text transcript. Processing: browser-based with Google's speech recognition servers. Requires: internet connection, microphone permission. Use case: dictation, meeting notes, accessibility.

What languages are supported?

Current version: en-US only (hardcoded). Web Speech API supports 50+ languages, but this tool does not expose language selection. For other languages: modify source code or use alternative tools. Accuracy: 95%+ for clear English speech.

How accurate is the transcription?

Accuracy: 95%+ for clear speech in quiet environments. Drops to 80-85% with: background noise, accents, fast speech, technical terms. Best results: speak clearly at normal pace, use external microphone, minimize background noise.

Does it work offline?

No. Web Speech API requires internet connection to send audio to Google's speech recognition servers. Offline mode: not supported. Alternative for offline: use Vosk, Mozilla DeepSpeech, or built-in OS dictation (macOS/Windows).

How long can I record?

No fixed time limit. Continuous recognition supported. Practical limits: browser memory (1-2 hours typical), internet stability. For long recordings: stop every 30 minutes, copy transcript, restart. Auto-stop: may occur after 60 seconds of silence.

Can I upload audio files?

No file upload. Real-time microphone input only. For audio files: play file through speakers while tool records (low accuracy), or use dedicated transcription services (Rev, Otter.ai, Google Cloud Speech-to-Text API).

Which browsers support speech recognition?

Full support: Chrome, Edge, Safari (desktop and mobile). Limited: Firefox (requires flag enable). Not supported: Internet Explorer, older browsers. Check: if you see alert message, browser lacks Web Speech API support.

Is my audio data safe?

Audio sent to Google's servers for processing (Web Speech API requirement). Not stored by this tool. Google may process for service improvement. For sensitive content: use offline alternatives (Vosk, DeepSpeech) or local transcription software.

Pro Tip

💡 Tip: For best accuracy, use an external USB microphone instead of built-in laptop mic. Speak at normal conversational pace (not too fast). Pause briefly between sentences. Avoid background noise (music, TV, other conversations).
