Show HN: I built an AI conversation partner to practice speaking languages

https://apps.apple.com/us/app/talkbits-speak-naturally/id6756824177
22•omarisbuilding•1h ago
Hi,

I built TalkBits because most language apps focus on vocabulary or exercises, but not actual conversation. The hard part of learning a language is speaking naturally under pressure.

TalkBits lets you have real-time spoken conversations with an AI that acts like a native speaker. You can choose different scenarios (travel, daily life, work, etc.), speak naturally, and the AI responds with natural speech back.

The goal is to make it feel like talking to a real person rather than doing lessons.

Techwise, it uses realtime speech input, transcription, LLM responses, and tts streaming to keep latency low so the conversation feels fluid.

I’m specially interested in feedback about: – Does it feel natural? – Where does the conversation break immersion? – What would make you use this regularly?

Happy to answer technical questions too.

Thanks

What's different between this and all other 10s of different ones doing the same?

This question maybe formulated too harsh, but it is valuable. There are quite a few similar applications (I think I tried 2 or 3 of them). Some are around for couple of years. What is new / unique in your approach?

I'm curious how the experience is different from using live voice mode in ChatGPT or Gemini?

Cool app. It takes a lot of courage to share here, so well done. I’d definitely highlight a bit more prominently what languages it supports though. The interface is very “Claude” so I’d be keen to hear about:

- How did you go about developing this?

- Was the entire thing vibe coded or just part of it? No shade either way, just curious.

- How long did it take?

- What were some of the harder hurdles to overcome?

- Given the use of AI, what’s your approach to security of your users data? How did you review any generated code?

Duolingo does this, but only for a few languages and it needs some improvement.

I just tried in Portuguese, and it introduces itself as ChatGPT. I was going to ask what can this do that ChatGPT can’t, but no need to answer now I guess.

Did it? It uses an openAI (gpt) model. I should refine the prompt. Thanks for the feedback!

Looks pretty good, the speech pipeline feels noticeably faster than the general-purpose apps I've used for lang conversations. Dead air kills immersion after all
