+
+### Speaking-Focused (most relevant to mic-based learning)
+
+- **companion** — closest to a full "talk to practice" solution out of the box
+- **discute** — purpose-built for speaking practice
+- **ai-english-tutor** — English-specific but demonstrates the tutor pattern
+
+### Infrastructure / Building Blocks
+
+- **speechbrain** — STT/TTS toolkit if building something custom
+- **libretranslate** — self-hosted translation backend
+- **linguacafe** — reading/vocab complement to speaking practice
+
+### Reference
+
+- **awesome-language-learning** — index of more projects worth exploring
+
+## Commercial Apps Worth Knowing About
+
+These can't be cloned but are worth evaluating alongside the open-source options:
+
+- [ChatGPT Voice Mode](https://chatgpt.com) — free-form conversation in any language (needs Plus sub)
+- [Langua](https://langua.io) (~$8-12/mo) — native-speaker-cloned voices, 23 languages, real-time feedback
+- [Talkio AI](https://www.talkio.ai) (~$10-15/mo) — 40+ languages, 134 dialects, pronunciation feedback
+- [Speak](https://www.speak.com) (~$15-20/mo) — structured curriculum, good for beginners
+- [ELSA Speak](https://elsaspeak.com) (~$6-10/mo) — phoneme-level pronunciation analysis (English only)
+
+## The DIY Stack
+
+If none of these fit, the common architecture for a custom speaking tutor:
+
+1. **STT**: [Whisper](https://github.com/openai/whisper) (local or API)
+2. **LLM**: [Claude API](https://docs.anthropic.com/en/docs) or [GPT-4o](https://platform.openai.com/docs) with a tutor system prompt
+3. **TTS**: [OpenAI TTS API](https://platform.openai.com/docs/guides/text-to-speech), [Coqui TTS](https://github.com/coqui-ai/TTS) (open source), or speechbrain
+
+## What Linguists Recommend (2025-2026)
+
+- Massive input first (listening + reading), then speaking practice
+- AI conversation daily for low-pressure reps
+- Human tutor 1-2x/week for nuance
+- Spaced repetition for vocab ([Anki](https://apps.ankiweb.net), etc.)
+- Consistency over intensity
