OPENTALKING_STT_DEFAULT_PROVIDER=dashscope
OPENTALKING_STT_DASHSCOPE_API_KEY=<dashscope-api-key>

Terminal

bash scripts/quickstart/start_mock.sh

/models Verification

Terminal

curl -s http://127.0.0.1:8000/models | python3 -m json.tool

Expected:

{"id":"mock","backend":"mock","connected":true,"reason":"local_self_test"}

Common Errors

Symptom	Action
LLM returns 401	Check OPENTALKING_LLM_API_KEY and OPENTALKING_STT_DASHSCOPE_API_KEY separately.
No browser video	Use a Chromium-based browser and inspect WebRTC/CORS errors.
Port conflict	Run bash scripts/quickstart/start_mock.sh --api-port 8010 --web-port 5180.

Frontend Entry

After the model or backend service is running, use the OpenTalking WebUI:

Terminal

cd "$OPENTALKING_HOME"
bash scripts/quickstart/start_frontend.sh --api-port 8000 --web-port 5173 --host 0.0.0.0

For a remote server, forward your local browser port to the server 5173, then open http://127.0.0.1:5173.
