Lucy vs SayHi Translation App
SayHi (by Amazon) is a voice-first translation app that excels at real-time spoken conversation. Speak in your language, and SayHi translates and speaks the result aloud — making it feel like having an interpreter in your pocket. How does this voice-focused approach compare to Lucy's visual, food-focused translation?
SayHi's Voice-First Approach
SayHi does one thing exceptionally well: voice-to-voice translation. Tap the microphone, speak naturally, and SayHi translates and speaks the result in the target language. The other person taps, responds in their language, and you hear the English translation. It's as close to real-time interpreting as a phone app gets.
Backed by Amazon's language technology, SayHi's speech recognition and synthesis are polished. The app is free, ad-supported, and supports a wide range of languages.
The Missing Sense: Vision
SayHi's critical limitation for travellers is the complete absence of camera translation. You cannot point SayHi at a menu, a sign, a label, or a ticket machine. In travel, visual translation is arguably more important than voice — you encounter written text constantly (menus, signs, schedules, labels) but have spoken conversations less frequently.
This isn't a criticism of SayHi's quality — it's a limitation of its scope. SayHi chose to excel at voice. Lucy chose to excel at visual translation with travel context. They're complementary tools.
When Voice Matters Most
Voice translation shines in specific travel moments: asking for directions when you're lost, communicating with a taxi driver, having a brief conversation with a local. These moments are important and stressful. SayHi handles them well.
When Vision Matters Most
Camera translation dominates the rest of travel: every restaurant menu, every street sign, every train timetable, every museum placard, every ingredient label. Lucy reads them all, adds context, and flags allergens. For the volume of translation a traveller actually needs, visual translation with Lucy covers more ground.

Our Verdict
SayHi and Lucy represent two different philosophies: SayHi is ears and mouth (voice in, voice out), while Lucy is eyes and brain (camera in, context out). For spoken conversation — haggling at a market, asking directions, chatting with a local — SayHi is fast and natural. For reading menus, understanding food, identifying allergens, and visual translation — which is what travellers need most — Lucy is in a different category entirely. The ideal travel kit includes both: SayHi for speaking and Lucy for seeing.
