How to Convert Speech to Text for Free

Two kinds of speech to text

Before picking a tool, it helps to know that "convert speech to text" covers two different jobs:

• Live dictation — you speak and the words are typed in real time. Best for writing emails, notes, and messages hands-free.
• File transcription — you already have a recording (a voice memo, an interview) and want the text out of it.

Most free options only do live dictation. A couple can do both. We'll flag which is which as we go.

Method 1: A free browser speech-to-text tool (fastest)

The quickest route needs nothing but a browser tab. A free tool like our Speech to Text tool uses the speech recognition engine already built into Chrome, Edge, and Safari: open the page, click the microphone, allow access, and your words appear as text the moment you speak them.

Why it's the easiest option:

• Nothing to install and no account to create.
• Unlimited and free — the recognition runs through the browser, so there's no per-minute cost.
• Works in 35+ languages — pick yours from the dropdown before you start.
• Copy, download as a text file, or read it back to proofread.
• A built-in on-device mode (see Method 4) covers Firefox, offline use, and existing audio files.

If you'd rather keep your text in a persistent scratchpad as you dictate, the same engine also powers our online notepad, which autosaves what you write.

If you're already writing in Google Docs, it has free speech-to-text built in. Open a document, go to Tools → Voice typing, click the microphone that appears, and dictate straight into the page.

Good for: dictating directly into a document you're already editing. Limitations: it only works inside Google Docs, only does live dictation (it can't open a recorded file), and outputs plain text with no formatting. For getting an existing recording into Docs, see our dedicated guide on audio transcription to Google Docs.

Every modern phone can convert speech to text for free from the keyboard. Tap into any text field, then tap the microphone icon on the keyboard and start talking.

• iPhone: the microphone key sits next to the space bar. Dictation is on by default in most regions.
• Android: tap the microphone on the Gboard keyboard (or your keyboard's equivalent) to use Google's voice typing.

Good for: quick messages and notes on the go. Limitations: it's tied to whatever app you're typing in, and it's live-only — no transcribing a saved recording.

The methods above are quick, but they send your audio to a browser or platform speech service to recognise it. If your notes are sensitive — or you're on Firefox, which has no built-in dictation — an on-device engine is the answer.

Whisper is OpenAI's open speech-recognition model, and it can run entirely inside your browser using WebGPU. Our Speech to Text tool includes a Whisper mode that downloads the model once, then transcribes with nothing leaving your device. Because it processes the full audio rather than a live stream, it's also the best free option for transcribing a recording you already have — just upload the file.

• Works in every modern browser, including Firefox.
• Runs offline once the model has downloaded.
• Nothing is uploaded — your audio and transcript stay on your computer.

Which method should you use?

All four are free. The right one depends on where you're writing and how private the content is.

For most people, a browser speech-to-text tool is the simplest place to start: it's instant, it covers 35+ languages, and it can switch to the private on-device engine when you need it. Reach for Google Docs Voice typing or phone dictation when you're already writing in those places.

Tips for better accuracy

Free engines are surprisingly good, but a few habits make a real difference:

• Use a decent microphone — a headset or earbuds beat a laptop mic across a room.
• Reduce background noise — recognition drops fast with a TV or café behind you.
• Speak at a steady pace — natural, not rushed, and don't trail off at the end of sentences.
• Say your punctuation — "period", "comma", and "new line" work in most dictation engines.
• Pick the right language — set the language to match how you're speaking, including the regional variant.

Frequently asked questions

How do I convert speech to text for free?

The fastest free way is a browser speech-to-text tool: open the page, click the microphone, and your words are typed as you speak. Google Docs Voice typing and your phone's keyboard dictation are also free. None of these require paying or installing anything.

Is speech to text free?

Yes. Modern browsers include a built-in speech recognition engine, so free tools can offer unlimited live dictation at no cost. Open-source models like Whisper can also run for free directly on your device.

Can I convert speech to text without an internet connection?

Yes, with an on-device engine. A tool that runs Whisper locally in your browser transcribes without sending anything to a server, so it works offline once the model has downloaded. Live browser dictation, by contrast, needs a connection because the browser processes the audio through its speech service.

Which is the most accurate free speech to text option?

For clean, close-talking speech, live browser and phone dictation are quick and accurate. For accented speech, background noise, or transcribing an existing recording, an on-device Whisper model is usually more accurate because it processes the full audio rather than a live stream.

Is free speech to text private?

It depends on the engine. Live browser dictation sends audio to the browser's speech service (Google in Chrome, Apple in Safari). An on-device Whisper tool keeps everything on your computer — nothing is uploaded — which is the private choice for sensitive notes.

Bottom line

Converting speech to text costs nothing in 2026. If you want one tool that does live dictation, private on-device transcription, and file uploads in one place, start with our free Speech to Text tool. And if you'd rather your voice notes did more than sit as text — landing structured in Notion, Google Sheets, Docs, or your inbox automatically — that's what SendMyVoice is built for.
