A few years ago, right after high school, I decided to try to make a simultaneous translation app for Android as a side project, it took longer than expected (about 2 years) and I had to make a lot of compromises (I had to use Google's API and therefore make users use a developer key because at the time there were no free solutions for speech recognition and translation that had good quality). At the end of university, I decided to pick it up again and finally, using OpenAi's Whisper for speech recognition and Meta's NLLB for translation (with both running locally on the phone), I managed to make it free and totally open-source (as it was meant to be from the beginning). The app is still in beta, so I would love your feedback. For now, the app is not in the Play Store, to install it download the apk on the GitHub releases and open it: https://github.com/niedev/RTrans...

A friend of mine has been looking for a tool like this for language learning. I’m excited to share this with them!

I admire the clean design and user-friendly interface. It makes using the app feel intuitive right from the start.

I can't wait to use this at family gatherings! No more awkward moments trying to translate Grandma’s stories!

I saw similar features in other apps, but the local processing really sets this apart. It feels like a step in the right direction for privacy-focused tools.

! it looks like a fantastic resource for anyone looking to overcome language barriers.

The idea of real-time translation running locally on the device. It really enhances privacy and usability, especially when traveling.

I recommend RTranslator for instant translation on Android. This open-source app works offline, ensuring privacy.

Congrats on the launch! It looks fantastic. How many languages are supported at the moment?

@luca_martino1 Impressive launch! Your app's seamless language translation with Bluetooth headphones is brilliant. At InterWiz, we revolutionize hiring with AI avatars conducting interviews for any time, anywhere convenience. How do you see your app enhancing remote team collaborations across different languages?

This sounds super useful! Just checked it out briefly but looks very promising. Great job and good luck with the beta!

Congrats @luca_martino1! This is an incredible achievement and truly a game-changer in the world of translation apps. Your journey from high school side project to a fully functional, open-source app using cutting-edge technologies like OpenAi's Whisper and Meta's NLLB is nothing short of inspiring. The ability to have real-time conversations in different languages with total privacy is revolutionary. I can't wait to try it out and provide feedback. Kudos on making such a valuable tool available for free to everyone! 🚀🎉

Congratulations on building and finally launching a simultaneous interpreting app! It's incredible that you've gone free and open source by utilizing OpenAI's Whisper for speech recognition and Meta's NLLB for translation - both running natively on your phone. It's really impressive to have seamless conversations with others using a Bluetooth headset, especially with the offline functionality and complete privacy protection. @luca_martino1

Congrats on the launch, @luca_martino1! 🎉 This is a game-changer for real-time communication and breaking down language barriers. The journey you took from a high school project to a fully functional app is truly inspiring. Combining OpenAi's Whisper with Meta's NLLB to make it both free and open-source is a commendable feat. Can't wait to try it out and see how it enhances conversations with people speaking different languages. Wishing you all the best in this beta phase and looking forward to seeing it on the Play Store soon! 🚀👏

I’m a simple man, I upvote open source softwares. Btw, so you use device side translation? It’s a breakthrough if you can provide high quality translation from the device side. Wish you success!

Congrats on the launch! 🚀 The ability to have real-time conversations through Bluetooth headphones with seamless translation is incredible! Love the focus on offline functionality and privacy!
