6 AI engines with smart routing. Dynamic Island waveform.PiP floating translation.Conversation & Lecture modes. Apple Translation free offline. Your voice stays on device
Language shouldn't be a wall between you and the world.
Every moment you can't speak up is a connection missed.
SayVox carries your voice across languages — speak, and be understood.
——
Conversation Mode — Face to Face, Naturally
Press record and speak your language. SayVox recognizes, translates, and reads it aloud to the other person — instantly. They reply, and it's translated right back. You speak English, they speak Japanese, but you're having a real conversation.
No typing, no waiting. It's like having an invisible interpreter by your side. Asking for directions, ordering at a restaurant, chatting with friends abroad — just speak.
——
Lecture Mode — Understand Every Word
Turn on Lecture Mode and let SayVox listen to the foreign language around you. Speeches, classes, news, broadcasts — translations appear line by line on your screen, like subtitles.
Put on your headphones and the translated audio goes straight to your ears while the phone's microphone keeps capturing the live sound. Just focus on understanding — SayVox handles the rest.
——
6 AI Translation Engines
SayVox integrates six world-class AI translation engines, unlocked progressively with your subscription:
Qwen — Specialized in CJK languages, outstanding Asian language performance
Gemini — Google's latest large language model
GPT-4.1 — OpenAI's flagship translation engine
DeepSeek V3 — High-performance deep reasoning engine
Gemini Flash — Lightning-fast, millisecond-level translation
Claude Haiku — Anthropic's precise semantic understanding
Smart Routing automatically selects the best engine based on your language pair, text length, and engine load. No manual switching needed — SayVox makes the best choice for you.
——
Apple Translation Built-in — Free, Offline, Instant
Even without internet, Apple's built-in translation works instantly. It doesn't use your subscription quota, doesn't need a connection, and doesn't upload any data. Your most reliable translation backup, always ready.
——
Picture-in-Picture Translation (PiP)
Switch to another app without interruption. PiP mode presents translation results in a floating window — translate while checking maps, browsing information, or messaging. Effortless multitasking.
——
Conversation History
Every conversation is saved automatically. Review your translations anytime, with export support for meeting notes or travel journals.
——
Haptic Feedback
Recording start, translation complete, language switch — SayVox uses 6 carefully designed haptic patterns so you can feel the app's status without looking at the screen.
——
Supported Languages
繁體中文, English, 한국어, 日本語, 简体中文

Privacy First
Your voice belongs to you alone. SayVox uses Apple's on-device speech recognition — your audio never leaves the device. AI translation only sends the recognized text, never the original voice.

AI translation results are for reference only and may not be perfectly accurate.
