SayHi: AI Voice Translator

Two people, two languages, one phone between you. SayHi listens, translates and speaks. Translation runs on your device with downloadable language packs, so once a pack is installed you can translate without data. No account, no ads, no SayHi servers.

🚀 GET STARTED
1. Pick your language and theirs
2. Download the two language packs — a minute on Wi‑Fi
3. Put the phone between you, tap your microphone and talk
4. Hand over the conversation: the other person taps their own microphone to reply

🗣️ TWO-WAY CONVERSATION
• Two language cards facing each other, each with its own microphone
• Just talk naturally — the latest line lights up as it is recognized and translated
• Your words appear in the other person's language and are read aloud with your phone's text-to-speech voice
• Tap the swap button to flip the two languages instantly
• Set "My language" and "Their language" once in Settings, and every conversation starts with the right pair

📵 TRANSLATE WITHOUT DATA
• Download a language pack once, keep it as long as you like
• Translation runs 100% on your phone once the pack is installed
• Translate on a plane, in the subway, or abroad without roaming
• Speech recognition and read-aloud use the speech services built into Android. On many phones they also work offline when the offline speech language is installed — check your phone's speech settings before you travel

💬 LIVE CAPTION MODE
• One-way bilingual captions for meetings, lectures and videos
• Set the phone down, let it listen to the room, and read along in your language

🎙️ MEETNOW — MEETING RECORDER
• Records in the background and builds a full conversation transcript with translations
• Keeps going when you leave the app or turn the screen off; a notification shows how many sentences have been transcribed
• Pause when there is a break and resume into the same transcript
• Start it straight from the MeetNow tile in your quick settings shade
• Transcripts are saved to history so you can review them any time

🌏 59 LANGUAGES
• Vietnamese, English, Japanese, Korean, Chinese, French, German, Spanish, Thai…
• Pair any two languages — Vietnamese with Japanese, Spanish with Korean
• Each language is a small pack; keep only the ones you need
• Search the language list, see which packs are downloaded, and delete a pack you no longer need to free up space

⌨️ TYPE & LISTEN
• Too loud — or too quiet — to speak? Type to translate
• Prefer not to type? Tap the voice input button and dictate into the text box
• Tap any sentence to hear it read aloud
• Copy a sentence, or send it to another translator app on your phone for a second opinion

🔊 SPEECH SETTINGS
• Turn automatic read-aloud on or off after each sentence
• Adjust the speaking speed so the other person can follow
• If your phone has no voice installed for a language, SayHi stays quiet rather than reading it in the wrong accent

🔒 PRIVATE BY DESIGN
• No SayHi servers, no account, no ads, no analytics SDK
• Conversation history lives only on your phone
• Turn history saving off in Settings, or clear it all in one tap
• SayHi never uploads or syncs your history anywhere

🎨 MAKE IT YOURS
• Pick your favorite accent color, light or dark theme
• A minimal design that keeps the focus on the conversation

💡 GOOD TO KNOW
• Language packs are downloaded once over the internet; after that, translation works offline
• Voice input covers the languages your phone's speech service supports; any of the 59 languages can be typed
• SayHi needs the microphone to hear you; it asks before it listens
• While MeetNow is recording it holds the microphone, so stop it before you start a face-to-face conversation
• Quick, natural sentences translate best — pause briefly between speakers

Install SayHi, download your two languages, and start talking — it takes a minute.
