Free AI Speech & Translation Tools in Your Browser

UMARIX AI Speech & Translation gives you five free tools that work entirely in your web browser: text to speech, speech to text, live audio transcription, language translation, and subtitle translation. You do not need to install an app, create an account, or upload a file to a server to use them. Open a tool, allow microphone access only when a tool asks for it, and get a result you can copy or use right away.

Start with a real task. A teacher can turn lesson notes into spoken audio for listening practice, then dictate the next lesson plan instead of typing it. A student can translate a short paragraph for homework and check the wording carefully, rather than trusting a machine translation blindly. A video creator can translate a short SRT subtitle file cue by cue and keep the original timing intact. A podcaster can draft show notes by speaking them aloud, then edit the transcript into clean text. Each tool page explains what it can and cannot do before you press a button, because browser tools have real limits and this site does not hide them.

The most important limit is browser support. Text to speech uses voices installed on your device, so the voice list changes from one computer or phone to another. Speech to text and live transcription use the browser speech recognition feature, which works best in Chrome and may not work at all in other browsers. Translation uses the free MyMemory public API, which can be slow or rate-limited during busy periods, and machine translation can still make mistakes with idioms and technical terms. Audio transcription on this site works with live microphone input only: a recorded file cannot be transcribed by browser speech recognition, so this site shows that limit clearly instead of inventing a transcript. If a tool cannot do something, its page says so and suggests the honest alternative.

To get the best results, use a quiet room, a close microphone, and short, clear sentences for speech tools. For translation, keep passages short, use simple sentences, and review names, numbers, and key instructions before you publish or send them. For subtitles, test a few cues first, check the timing in your video player, and then translate the rest. All five tools are free, work without signup, and keep your work in your browser wherever the tool design allows it.

Frequently asked questions

Do I need an account to use these tools?

No. Every tool on this site works without signup.

Why does speech recognition not work in my browser?

Speech recognition is a browser feature, not a feature of this website alone. Chrome supports it most widely; other browsers may not support it at all.

Are translations accurate?

Machine translations are useful for everyday meaning but can be wrong. Check important text, especially names, dates, instructions, and legal wording.

Do you upload my audio or text?

Text to speech and speech tools run through your browser. Translation requests go directly from your browser to the free MyMemory API for that request only. This site does not store your tool inputs on its own server.
