Devices with a microphone and screen capable of translating live speech and text.

They support two-way (duplex) translation: you speak — the device translates to the other person, and vice versa.

They feature a touchscreen and several buttons for selecting the language and translation direction.

Size — approximately like an MP3 player or a pocket-sized phone.

Supports dozens — up to around 140 languages (including offline support for ~15–20).

Operating modes: online (with internet) and offline (which is convenient for travel).

Photo translation — some models can translate text in images (e.g., signs, menus).
