Lven Instant / Android

Voice to text for Android that stays on your phone.

A bubble over whatever app you are in. Tap it, speak, and Lven Instant types what you said, with the punctuation, into the field you were using. The speech model runs on the phone, so your voice is never uploaded.

Google Play serves 0.9.55; the direct download below is 0.9.56.

Download directly

This is the official direct release build from ClassEve rather than the Play Store channel. Android asks you to approve installation from your browser or file manager.

If you already have Lven from Google Play, uninstall it first — this build installs separately. That clears your local history and taught words, and you sign in again.

The first build below is for arm64 devices; the second is for older 32-bit ARM hardware.

  1. When you open the downloaded file, Android may warn that installs from this source aren’t allowed yet. Tap Settings, turn on Allow from this source, then go back and tap Install.
  2. Open Lven and grant the microphone permission. Enable “display over other apps” if you want the floating bubble, and Accessibility to type into other apps.

Missed one? Turn it on by hand — the permissions screen sits in a slightly different place depending on your phone:

  • Samsung: Settings → Apps → Lven → tap the ⋮ menu (top-right) → Permissions. Grant the microphone permission; “Appear on top” is under Special access.
  • Xiaomi / Redmi / POCO: Settings → Apps → Manage apps → Lven → scroll down to the large Permissions button. Some versions place overlay access under Other permissions; Autostart may help only when the phone stops the bubble.
  • Pixel / OnePlus / Motorola / others: Settings → Apps → Lven → Permissions for microphone access. Overlay access is usually under Special app access → Display over other apps.

Why this build

Why Lven Instant on Android

Most keyboards' microphone buttons send your voice to a server. Lven Instant does not: the model runs on the phone, so it works on a flight, on the subway and anywhere reception is bad, and nothing you say is stored or sent anywhere.

It works across apps. The bubble floats above WhatsApp, Gmail, Chrome, Slack, your notes app and anything else with a text field, and the transcript lands at your cursor. Android's Accessibility service is used for exactly one thing — finding the field that has focus — and the app reads nothing else on screen.

It is the same engine as the desktop builds: measured about six times faster than you speak on consumer-grade hardware with a 3.76% word error rate, and it adjusts itself to your phone's processor. Needs Android 10 or later and a phone with 4 GB of memory, which the app checks before it starts.

One account, five devices. The phone, the laptop and the Linux desktop share it, and it is free.

Dictate in 25 European languages, detected automatically.

FAQ

Common questions.

Does the voice to text work without internet on Android?
Yes. Transcription runs on the phone once the model is installed. Sign-in, the one-time model download and access checks use the network; none of them carry audio.
Does it work in WhatsApp, Gmail and Chrome?
Yes. The floating bubble works over any app with a text field. Grant the Accessibility permission and the transcript is typed into the focused field; without it, the text goes to the clipboard for you to paste.
Should I install from Google Play or the direct APK?
Both are official builds. Google Play updates on its own review schedule, so the direct download can be a version ahead. Pick one and stay with it: the two are signed with different keys, so a Play install updates from Play and a direct install from this page.
What phone do I need?
Android 10 or later and a phone with 4 GB of memory; the app checks before it loads the speech model and tells you plainly if there is not enough. There are two downloads, one for current phones and one for older 32-bit phones.
Does it need an internet connection to transcribe?
No. Transcription runs on your own device. Sign-in and the one-time model download use the network; no audio or text ever does.
Is there a daily limit or a word cap?
No. There is no server in the transcription path, so there is nothing to meter. Dictate all day on every device you link.
What does it cost?
Lven Instant is free: make a ClassEve account, link the app, and use it on up to 5 devices.
