How Zahvox works in Brazil
Chrome and Edge can show live text when built-in speech recognition is available. Browsers without that feature, such as Firefox, use record-then-transcribe: speak, press Stop, and wait for the result. Microphone access, a compatible device, an internet connection, and service availability are required; behavior varies by browser and platform. To start, open /tool in a supported browser and grant microphone permission. With built-in recognition, text can appear as you speak. With the fallback, press Stop and wait for the transcript. Review and edit the result — Zahvox is a writing surface, not a multi-speaker meeting recorder.
With built-in browser speech recognition, audio may be sent to the browser vendor's speech service. In browsers without that feature, such as Firefox, Zahvox records up to five minutes and sends the audio through its transcription endpoint to an AI provider after you stop. The current tool does not save recordings or transcripts to a Zahvox account or database. Provider processing and retention follow their own policies; this is not an offline or device-only service. Avoid sensitive or confidential information. You can copy the final text or download it as a plain text file.

Language and accent support in Brazil
Language options to try: Portuguese (Brazil), English (US).
The menu offers 21 language and regional options, including Urdu, Hindi, Arabic, French, German, and Brazilian Portuguese. Select a language in the tool, not in your browser settings. Recognition quality and availability vary by service and platform; a menu option is not an accuracy guarantee. Accuracy varies with the recognition service, language, accent, microphone, and background noise. Zahvox has not published a measured accuracy score. Review names, numbers, punctuation, and important details before using the transcript.

Zahvox vs. voice-to-text alternatives available in Brazil
Brazil users have three main options for turning voice into writing today. None of them are wrong — they just solve different problems. Here is an honest comparison so you pick the right tool for the job.
| Tool | Best for | Cost | Signup |
|---|---|---|---|
| Zahvox | Solo writing — emails, notes, drafts | Free core tool | Not required |
| Built-in OS dictation | Typing into any app quickly | Free with your OS | System account |
| Browser-based free tools | Similar solo writing use | Free | Varies |
| Paid meeting transcription | Multi-speaker meeting notes | Subscription | Account required |
Zahvox's honest edge is the writing surface — a clean workspace built for editing what you just said, with zero signup and zero install. For multi-speaker meeting notes, use a dedicated meeting tool. See a longer breakdown on the alternatives and compare pages.
FAQ — Voice-to-text in Brazil
Does Zahvox work in Brazil?
Yes. Zahvox is fully available across Brazil. The free web tool works in Chrome on Android and Windows, plus Edge and Safari, with no signup and no local install required.
Can I dictate in Portuguese with Zahvox?
The menu offers 21 language and regional options, including Urdu, Hindi, Arabic, French, German, and Brazilian Portuguese. Select a language in the tool, not in your browser settings. Recognition quality and availability vary by service and platform; a menu option is not an accuracy guarantee.
Is Zahvox LGPD compliant in Brazil?
Do not assume this tool is certified compliant or that online dictation exempts you from privacy laws. For professional use, assess local requirements, consent, and provider policies. Avoid confidential or sensitive data. With built-in browser speech recognition, audio may be sent to the browser vendor's speech service. In browsers without that feature, such as Firefox, Zahvox records up to five minutes and sends the audio through its transcription endpoint to an AI provider after you stop. The current tool does not save recordings or transcripts to a Zahvox account or database. Provider processing and retention follow their own policies; this is not an offline or device-only service. Avoid sensitive or confidential information.
Is voice-to-text accurate?
Accuracy varies with the recognition service, language, accent, microphone, and background noise. Zahvox has not published a measured accuracy score. Review names, numbers, punctuation, and important details before using the transcript.
Does voice-to-text work offline?
The current tool requires an internet connection for recognition. Neither built-in recognition nor the record-then-transcribe fallback is advertised as an offline mode.
Is my voice data private when using an online voice-to-text tool?
With built-in browser speech recognition, audio may be sent to the browser vendor's speech service. In browsers without that feature, such as Firefox, Zahvox records up to five minutes and sends the audio through its transcription endpoint to an AI provider after you stop. The current tool does not save recordings or transcripts to a Zahvox account or database. Provider processing and retention follow their own policies; this is not an offline or device-only service. Avoid sensitive or confidential information.
What is the difference between voice-to-text and dictation?
Dictation is a broad term for speaking your writing. Voice-to-text is the technology that converts speech into written characters. Zahvox is a voice-to-text web tool built for writing — not for transcribing meetings with multiple speakers.
Do I need to install anything to use Zahvox?
No. Zahvox runs entirely in your browser. Open the tool page, grant microphone access once, and start speaking. There is nothing to install, no signup, and no download for the current free experience.
Which browsers support voice typing?
Chrome and Edge can show live text when built-in speech recognition is available. Browsers without that feature, such as Firefox, use record-then-transcribe: speak, press Stop, and wait for the result. Microphone access, a compatible device, an internet connection, and service availability are required; behavior varies by browser and platform.
Can I add punctuation by voice?
Yes. Say the punctuation word — for example, 'comma', 'period', 'question mark', or 'new line'. Different browsers handle punctuation commands slightly differently, so a quick edit pass at the end is normal for polished writing.
Is Zahvox really free?
The current tool is free to use with no signup or card. Built-in recognition can pause or stop during a session. The record-then-transcribe fallback allows up to five minutes per recording and is subject to service availability and request limits.
How is Zahvox different from Google Voice Typing or Apple Dictation?
Built-in OS dictation is a system feature that types into any app. Zahvox is a dedicated writing surface with editing tools, one-click copy, and download — plus a clean workspace for polishing the draft, not just capturing it.
How is Zahvox different from Speechnotes or Otter.ai?
Speechnotes is the closest browser-based free alternative. Otter.ai is a paid meeting transcription tool with speaker labels and account storage. Zahvox is a free, no-signup writing surface — best for solo writing, not multi-speaker meetings.
Can I export or download the transcribed text?
Yes. You can copy the text with one click or download it as a plain text file directly from the tool. The current tool does not offer saved transcript history; copy or download your draft before closing the tab.
Does Zahvox work for meetings with multiple speakers?
No. Zahvox is built for one voice — your writing. For multi-speaker meeting transcription with speaker labels, use a dedicated meeting tool. Zahvox provides a workspace for your own draft, without speaker labels.
