AI Analysis

Voice mode that uses full Claude/GPT-4 instead of lite models; waits minutes, not seconds.

Strengths

•Honest trade-off: rejects real-time voice UX to enable frontier model access (Opus, GPT-4o, Gemini Pro).
•Hands-free multi-turn with VAD, TTS voice choice, and playback controls—feels like a finished product.
•No backend—direct provider API calls from device, so no server costs or data leakage risk.

Weaknesses

•Android-only; no iOS port yet (author explicitly asking for help).
•Latency-first design is niche: mass market wants instant feedback, not five-minute think times.

Post Description

Introducing SlothSpeak: An open-source, bring-your-own-API-keys, mobile app for voice chat with LLMs that prioritizes response quality over latency.

APK file available on GitHub in the releases. Currently only for Android. Is anyone interested in porting to iPhone?

My preferred way to interact with LLMs is talking and listening while I'm walking, biking, driving, etc. The problem with the apps from the frontier labs is that their voice mode prioritizes real-time interactions and so they use watered down models.

Even today with a paid subscription, ChatGPT Voice will tell you there are two r's in strawberry. The answers are also relatively brief and so there is a need to chain together a series of simpler requests when you want to do a deeper dive.

SlothSpeak goes to the opposite end of the spectrum. It might leave you hanging for a few minutes but when it gets back to you, it will be an answer from a state of the art model. You can even do deep research queries to get very long and comprehensive responses.
