EnglishChunks.guru — speak real English, one chunk a day, scored by open-source AI

Description and use

EnglishChunks.guru teaches English chunks daily with instant pronunciation scoring and phoneme‑level feedback using open-source models, keeping voice data private.

Problem

English learners freeze when speaking because they learn words but not natural phrases; pronunciation feedback usually relies on closed cloud APIs.

Outcome

EnglishChunks.guru enables daily chunk practice with instant pronunciation scoring and phoneme‑level feedback, while keeping voice data private and reducing costs to $7–$11/month.

Workflow

• Learn the chunk and hear three real examples
• Speak the chunk twice and receive a score and sound‑fix tip
• Write three sentences using the chunk and get polished feedback
• Read the sentences aloud and receive a score

Evidence

Many learners know the words but freeze when they have to speak.

The open models do the core job — listening to your voice and coaching you:

The scoring service is Python/FastAPI on one DigitalOcean Droplet (2 vCPU, 4 GB). A score comes back in ~1.1 s on a typical recording.

Your voice never goes to a third-party API. Recordings are scored in memory on my server and deleted immediately.
