Live testing

Use the Keyword Spotting model test to evaluate your model with your microphone before deploying it. The test runs in the browser and lets you tune detection behavior in real time.

To run the test, complete the following steps:

• Test with your microphone — Select the microphone button to start, then say your commands and observe how the model responds in real time. While listening, the test gives you a few seconds to say a command. You can adjust the detection settings while testing.
• Set detection settings — Adjust the threshold and the number of predictions in a row for each command to control detection sensitivity and stability.
• Refine until detection is reliable — Repeat testing and fine-tuning to balance missed detections and false triggers.
• Use the final settings in your application — Once you are satisfied, apply these values in your firmware (C library).
