Stenograf: Speech to Text

Turn speech into text and translate conversations on your phone. Stenograf is a voice recorder with live transcription, speaker labels and timestamps. Search saved recordings, read what was said, and export a transcript or the audio.

Use your phone's microphone to record discussions, interviews or lectures. Transcription and translation run on your device after the required models are downloaded. The Android app is free and requires no account or in-app purchase.

RECORD AND READ
Start a recording with one tap. Follow the transcript as you speak, then open it later in Records. Speaker labels and timestamps make conversations easier to follow. Teach Stenograf familiar voices so it can show saved names when the voice match is clear. Speaker analysis continues through longer recordings.

TRANSLATE SPEECH
Choose a source and target language for conversation translation. The app offers English, Spanish, French, German, Italian, Portuguese and Russian. With connected headphones and a supported offline voice, hear spoken translations privately. Otherwise, read the translated text on your phone.

KEEP YOUR RECORDS USEFUL
Search saved recordings and translations. Save a transcript as Markdown or save the audio to a folder you choose. Manage audio storage and keep your transcripts after audio cleanup.

OPTIONAL VOICE CONTROLS
Start Assistant to listen for “Hey Soniqo, start recording” and “Hey Soniqo, stop recording” while the app is open. Assistant is experimental and marked Beta. It stays off until you start it. Exit or leave the app to stop listening. Recognition can miss a command, so check the recording state.

WORK OFFLINE AFTER SETUP
Choose a model download source on first launch and download the speech models. Once the required models and translation languages are prepared, recording, transcription and translation work on your phone without an internet connection. Initial speech model downloads total approximately 1.3 GB; translation languages download separately.

CONNECT TO YOUR DESKTOP
Optionally pair with Stenograf on your desktop to send phone recordings over your local network. A desktop is not required to record, transcribe or translate on Android.

Transcription, translation and speaker matching can make mistakes. Check important wording and speaker labels against the recording.

Requires Android 10 or later.
