Full prompt template: use Gemini API CLI and headless Chrome to test voice features without a mic

_philschmid · x · 2026-11-05

Phil Schmid published the complete prompt template: install npx skills add google-gemini/gemini-skills --skill gemini-api-cli -y, then have an agent test voice/audio features end-to-end without a physical mic. It locates how the app opens microphone capture, generates spoken WAV test files with gemini-api TTS, launches headless Chrome with --use-fake-ui-for-media-stream --use-fake-device-for-media-stream --use-file-for-fake-audio-capture=/abs/path/voice.wav%noloop, clicks the mic button so getUserMedia streams the WAV, and verifies the feature works.
