Hi all,
There are many language-learning apps, but almost none that focus on improving conversational Hindi for kids. Made this web app for my nephew, based in Singapore, with the idea of having a 24×7 companion to practice his Hindi, given he rarely gets to speak Hindi with his friends. 20Mn+ Indian families live abroad, and I am sure many parents have experienced their children not getting enough conversational Hindi practice outside the home or in classes.
The stack involves STT+LLM+TTS with latency optimizations built in. There is also a correction module which highlights all the mistakes that the kid has made after 4 back-and -forths with the tutor. Going through this project also highlighted how far we still are when it comes voice AI latency for Indic languages. Finally settled with Google Cloud STT(surprisingly the best fit despite every new startup claiming their STT is best), used Llama-70b hosted on Groq(super fast) and Elevenlabs for TTS(the best expressivity). Tried multiple other providers across the stack but didn’t find their latencies coming through for Indian languages.
The app allows parents to view the kids’ conversation history and analytics. Will solidify the Analytics section basis the feedback from users on the main conversational feature.
Looking for feedback on the core premise of the app:
1. Does the flow of the conversations feel right?
2. Parents: would you pay for this?
Will soon be sharing the Github repo for this; the stack can be extended to multiple Indian languages and catered to different age groups. Will be sharing a detailed writeup soon on my experience with difference voice API providers, latency optimizations and design choices.
Thanks!
