How does the Lingolet ONE differ from other hand-held or in-ear translators in terms of voice translation? (Iflytek, Google pixel buds, pilot, Ili and etc)

Language communication is complex and multi-scene, so there are many different ways of interaction.

For example, the Iflytek Translator II, which costs 2999 RMB, comes with a 4G + WIFi connection, making it more upscale.

Google Pixel Buds, one speaks through a pair of headphones, while the other understands the translated language through a hand-held mobile phone with Google translating APP. The phone you're using needs to support Google Pixel and There is no difference than translation APP.

In-ear Headphones need to share a headset to each other and ask each other to download an App to connect.This type of interaction applies more to acquaintances than to strangers.

Ili Translator supports one-way off-line communication, the advantage is off-line, the weakness is one-way, it is difficult to achieve normal two-way communication.

The above products solve the problem of language communication basically through machine translation. Lingolet ONE uses a combination of machine and human translation to solve the problem of short, complex, professional and emergency conversations. At the same time, the price is reasonable, so that more people can afford and can experience the fun of language technology.
