Learning and careers decision
Elispeak
A technical user can build a useful, narrow replacement (real-time practice + basic feedback) using existing ASR and LLM APIs and prior-art repos, but reproducing Elispeak's polished curriculum, tuned pronunciation models, and product polish would be larger effort.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Elispeak alternatives, with the arithmetic →
What a replacement has to do
- User speaks into the app → audio is transcribed → system analyzes pronunciation/grammar and returns actionable feedback → user repeats corrected utterance and progress is recorded.
What it still won’t have
- Polished curriculum, topic catalog and UX polish
- Proprietary pronunciation-analysis models and tuned scoring
- Mobile app and cross-device polish
- Marketing, brand and user acquisition
- Instructor/teacher features and classroom flows
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal web-based AI English speaking tutor using Next.js for the frontend, Node.js/Express for the backend, PostgreSQL for storage, and WebRTC/getUserMedia for audio capture. Core features in scope: topic selection, real-time audio capture and upload, ASR integration (call a cloud speech-to-text API), a simple feedback engine that compares transcripts to expected answers and returns grammar/pronunciation hints, repeat/retake flow, minutes/quota accounting, user auth, and a dashboard showing per-session progress. Out of scope: mobile native apps, advanced pronunciation phoneme-level alignment, paid subscription billing integration, and a polished curriculum. Include error handling for network and ASR failures, automated tests for backend endpoints, and Docker deployment scripts for hosting.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
