Zephyr Flow

Turn speech into text on your Android phone with Zephyr Flow. Dictate notes and messages, transcribe audio files, or scan printed text with your camera. Speech recognition and OCR run on your device after the initial model download. No Zephyr account, ads or subscription.

DICTATE AND COPY
Use the microphone on Home or the optional floating bubble. Dictate into a selected text field with confirmation, or keep the result on the clipboard for manual pasting. Dock the bubble at the edge or hide it when you do not need it.

Basic mode gives you a fast transcription. On phones that pass the on-device check, Smart and Refined can correct or polish your words, and Instant translate can turn speech into your chosen target language. Dictation supports 25 spoken languages.

SPEAK LESS WITH INPUT BOOSTER
Save a reusable text and recall it with a short spoken phrase. Input Booster works with Basic dictation too and asks for confirmation before insertion. Use it for a standard reply, a template or a signature. Add names, acronyms and specialist terms to your personal dictionary, and use voice commands for lists, headings and emphasis.

TRANSCRIBE AUDIO AND SCAN TEXT
Import an audio file, edit its transcription and export documents. Scan signs, menus and printed pages with your camera, then copy the recognized text. On compatible phones, translate scanned text locally or listen with an installed offline voice.

YOUR TEXT STAYS UNDER YOUR CONTROL
Zephyr keeps encrypted history on your device for up to 14 days. Google Drive backup is optional: it can save settings, dictionary, Input Booster and usage totals in the app's private Drive space. Text history backup is a separate option, off by default. Voice processing stays local.
