Isolait – Voice Isolation

Hear one person in a noisy room. Lock onto a single voice at a loud restaurant or family dinner and filter out the rest — live, on-device, in your headphones.

Isolait helps you hear one person in a noisy room. It locks onto a single voice — at a loud restaurant, a family dinner, a busy meeting — and filters out the chatter, clatter, and other speakers around it. Live, on your iPhone, through your headphones.

WHY ISOLAIT Most amplifier and listening apps make the whole room louder, or remove background noise but can't tell one person's voice from another's. Isolait can. Lock onto the person you want to hear and their voice comes through clean — in real time, entirely on your device. Nothing is uploaded to isolate your audio.

HEAR ONE PERSON IN A NOISY PLACE

1. Put in your headphones. Any pair works: AirPods, other Bluetooth earbuds, or wired.
2. Point your iPhone toward the person you want to hear.
3. Tap Voice Lock to lock onto their voice. Made for noisy restaurants, cafés, family dinners, parties, meetings, and lecture halls — and for anyone who finds conversation hard to follow once a room gets loud. A parent who struggles at the dinner table can save the family's voices once and relock in a tap.

VOICE LOCK Real-time isolation of one speaker's voice. Voice Lock follows the person's voice itself, not just where the phone is pointed, so it can stay on them while other people nearby are talking. Lock onto anyone in seconds, or save their voice profile to relock instantly next time.

SAVED VOICES Build a library of voice profiles for the people you talk to most — family, coworkers, interview subjects — so isolating their voice is instant.

DIRECTION MODE Target a voice by where it's coming from, not just what it sounds like — useful when several people are talking at once. Also records a session with a live transcript, just like Voice Lock.

TRAVEL MODE Point your phone at someone speaking another language and hear a live translation, hands-free. An experimental two-way Conversation Mode lets each of you speak your own language, with both sides translated live. Free to use every day.

STUDIO Import a video or audio file, or film right in Isolait, then run on-device AI Clean Up to strip background noise. Turn on Transcribe for a speaker-labeled transcript you can translate and export with the cleaned-up audio or video.

IDENTIFY SPEAKERS Built for podcasts and interviews: Isolait labels who's speaking in a multi-person recording. Saved Voice Profiles are labeled by name; everyone else is "Speaker 1," "Speaker 2," and so on. Transcription stays on-device by default; an optional Enhanced Transcription setting offers more complete, off-device recognition for a specific recording when you choose it.

RECORD, CLEAN UP, TRANSLATE & EXPORT Record an isolated session with a live, speaker-labeled transcript. Clean it up, translate it into 20+ languages, or both — then export audio (or video) and transcript together.

PRIVATE BY DESIGN Voice isolation and cleanup always run on your iPhone. No account, no login, no uploads to hear the person in front of you.

Isolait is a listening tool, not a medical device or a hearing aid, and is not a substitute for professional hearing care.
