>Open source real-time translation app for Android that runs locally
Conversation mode:
- When you talk, your phone (or the Bluetooth headset, if connected) will capture the audio.
- The audio captured will be converted into text and sent to the interlocutor's phone.
- The interlocutors' phone will translate the text received into his language.
- The interlocutors' phone will convert the translated text into audio and will reproduce it from its speaker (or by the Bluetooth headset of the interlocutor if connected to his phone).
- Each user can have more than one connected phone so that you can translate conversations between more than two people and in any combination.
>Connect to someone who has the app, connect Bluetooth headphones, put the phone in your pocket and you can have a conversation as if the other person spoke your language.

😤 出国玩一趟，翻译 App 全要联网还要会员。RTranslator 1 万星，安卓完全离线：两人对话同时听、各说各的语言实时互译；连蓝牙耳机说一句对方耳机里就出译文；模型在手机里，没网也能用，录音不上传。 niedev/RTranslator
