Echo Lite: Voice Changer & Soundboard by Escalera Labs SL

Change your voice and play your own sounds in browser calls. Echo Lite is a free voice changer and soundboard for Firefox, with live AI voices, real-time voice effects and sound clips you choose.

FIND YOUR VOICE

Pick an AI voice, go deep, or sound like a robot. Switch voices while you talk, or use Hear myself with headphones to try a voice before your call.

MAKE THE SOUNDBOARD YOUR OWN

Bring your own sound clips and keep your favorite reactions ready. Preview sounds before sending them, and set separate volumes for what you hear and what the call hears. Make a Situation to pick a fitting reaction from your mix with one click.

GET INTO THE CALL

Open your calling website, open Echo Lite from the browser toolbar and choose Connect site. Keep your usual microphone selected. Already in a call? Refresh the tab and rejoin after connecting.

START FREE

Try Gamer Girl, Deep and Robot, play your own sounds and edit one included Situation without an account. Echo Pro unlocks more voices, custom effects and extra Situation slots. Already have Echo Pro? Sign in with the same Echo account. Paid plans are purchased on Echo's website.

MADE FOR BROWSER CALLS

Echo processes audio on your device and supplies the outgoing audio to the calling website you connect. Echo Lite does not add a system microphone for native apps or games. Calling websites can apply their own speech processing, and AI performance depends on your device. Managed school or workplace devices may restrict installation or microphone access.

YOUR CHOICE

Enable Echo only on the sites you choose. Signing in contacts Echo's account service to check your account and Pro access. Library media you request is downloaded from soundboard.pro and its media service. Optional usage reports stay off until you opt in through Echo Settings; those reports exclude audio, recordings and browsing URLs.

For desktop Firefox 140 or later. Optional usage reports also require Firefox's data permission. Use the extension's own soundboard library and import controls; the soundboard.pro website's Open in Echo handoff is not supported in this Firefox version.
