How to Transcribe Speech to Text for Free

Need to convert a voice memo, meeting recording, or dictated notes into text? Your browser can do it — no subscription, no upload, no privacy risk.

Why browser-based transcription?

Popular transcription services like Otter.ai, Rev, or Trint require uploading your audio to their cloud servers. This creates several problems:

• Privacy risk — Your conversations, medical notes, or legal dictation sit on someone else's server
• Cost — Most services charge monthly subscriptions or per-minute fees
• Delay — Upload + processing + download takes time
• Account required — You must create an account and accept terms of service

How the Web Speech API works

Modern browsers include a native speech recognition engine through the Web Speech API. Here's what happens:

1. You grant microphone access to the browser
2. Your operating system's speech engine processes the audio (Windows Speech Recognition, macOS Dictation, Android Speech Services)
3. The transcribed text streams back to the webpage in real-time
4. Nothing is sent to Presend's servers — the entire pipeline is local

Supported languages

Language support depends on your browser and operating system. Most systems support:

• English (US, UK, Australia, India)
• French, Spanish, German, Italian, Portuguese
• Japanese, Korean, Chinese (Simplified and Traditional)
• Arabic, Hindi, Russian, Dutch, Polish, Turkish

If a language isn't available, your browser will fall back to the closest supported variant.

Best practices for accuracy

• Use a good microphone — Built-in laptop mics work, but a USB headset or dedicated mic improves accuracy significantly
• Minimize background noise — Quiet rooms produce cleaner transcripts
• Speak clearly — Enunciate and maintain consistent volume
• Pause between sentences — Helps the engine segment text correctly
• Check punctuation — The API inserts some punctuation automatically, but you may need to edit

Limitations

• Firefox does not support speech recognition (only synthesis). Use Chrome, Edge, or Safari.
• Long sessions may timeout after 60 seconds in some browsers. Simply restart if this happens.
• Accents and dialects may reduce accuracy for less common variants.
• Specialized vocabulary (medical, legal, technical) may require post-editing.
