Audio and podcasting decision
Glossa.live
A competent engineer can build a useful, single-language or limited-multi-language replacement using open-source projects and hosted speech/translation APIs, but reproducing Glossa's full product (voice cloning, 100+ polished languages, integrations, and scale) is larger and operationally heavier than a one-person project.

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 Glossa.live alternatives, with the arithmetic →
What a replacement has to do
- Capture live audio → perform real-time ASR → translate text into target language(s) → (optional) synthesize translated audio → stream captions and audio to web clients.
What it still won’t have
- Voice cloning feature (requires trained/specialized TTS models and licensing)
- Biblically-trained model nuance (specialized training data and curation)
- Polished integrations (OBS, ProPresenter iframe/webhook prebuilt connectors)
- 24/7 phone support and SLA-backed reliability
- Scale-infra for many simultaneous streams and unlimited listeners
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal real-time church translation service using Node.js (or Python) backend, Postgres, Redis, and a React web client. In scope: 1) ingest audio via WebRTC or RTMP, 2) chunk and forward audio to a hosted streaming ASR API (or Whisper running in a GPU instance), 3) call a translation API for streaming target-language text, 4) optional TTS per-language using a hosted TTS API, 5) deliver captions and audio to listeners via WebSocket/SSE with a simple React UI to choose language and start/stop streams. Out of scope: multi-tenant billing, voice cloning, enterprise integrations, and mobile native apps. Include error handling for network/audio failures, basic logging, automated tests for the audio ingestion and translation pipelines, and deployment scripts (Docker Compose or Kubernetes manifests) with cost estimates for required cloud GPU/CPU instances and API usage.

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.
