Language learning is a fascinating and rewarding hobby, especially in our current era of technological advancement. As both a language learner and a mobile app developer, I couldn’t ignore the itch to build my own language learning app: NativePal.

To truly know a language means being able to speak it, write it, use grammar correctly, and understand spoken conversation. In this talk, I’ll walk you through the technical solutions powering those skills, including:

Text-to-Speech: How can you generate natural, emotionally expressive audio in both popular and obscure languages, without sounding robotic or breaking the bank?

Speech-to-Text: How do you accurately understand what the user says and provide meaningful, personalized feedback?

Grammar feedback: Can AI be trusted with grammar correction, especially for less commonly taught languages?

Localisation: What does it take to support 50+ languages, including RTL scripts, realistically and maintainably?

... and more!

This talk will provide deep technical insights and practical takeaways for anyone building (or dreaming of building) a language learning app or interested in the underlying technologies.
