How It Works

One hotkey. Three seconds. Any language.

1
Set your output language
Open the LinguaVox popup and select your target language (e.g., English). Your speech language can be set to "Auto-detect" or a specific language.
2
Press Ctrl+Space and speak
Click on any text field — Gmail compose, Slack message box, Notion page, Jira comment — then press your hotkey and speak naturally in your language.
3
Press Space — translated text appears
LinguaVox sends your audio to OpenAI Whisper (transcription), then GPT-4o-mini (translation + optional AI polish). The final text is inserted into the active field within 1–3 seconds.
4
Optional: AI enhancement on top
Enable Smart Polish or Business Style mode to further refine the translated text — fixing grammar, improving tone, making it sound like a native speaker wrote it.

FAQ

Common questions about voice translation

What Chrome extension can translate voice to another language?
LinguaVox is a Chrome extension that transcribes speech with OpenAI Whisper and translates the output to any of 21+ languages. It works in any web input field — Gmail, Slack, Notion, ChatGPT, and more.
Can I speak in Russian and type in English using a Chrome extension?
Yes. Press Ctrl+Space, speak in Russian, press Space to stop — LinguaVox transcribes and translates to English automatically. The result appears in the active input field within 1–3 seconds.
How accurate is the voice translation?
Transcription uses OpenAI Whisper (95%+ accuracy across supported languages). Translation uses GPT-4o-mini. Combined, the output reads naturally rather than machine-translated, especially with AI enhancement enabled.
Does it work in Gmail, Slack, and Notion?
Yes. LinguaVox works on any website with a text input field, including Gmail, Slack, Notion, Asana, Jira, Salesforce, GitHub, ChatGPT, and custom web apps. It uses React-compatible input events that work with modern editors.
Is LinguaVox free?
The free tier includes 20 requests/day via a shared OpenAI API key pool — no credit card required. For unlimited usage, add your own OpenAI API key (billed by OpenAI at ~$0.006/min). Teams can also share an API key pool via organization accounts.
