9.1Voice Interface Testing

Voice-driven features (Siri Shortcuts, Google Assistant actions, in-app voice commands) require a different testing approach. You are not testing a visual interface -- you are testing a natural language understanding (NLU) pipeline that converts spoken words into structured intents and entities.

The core challenge: speech-to-text produces variable transcriptions. The same spoken phrase may be transcribed differently depending on accent, background noise, microphone quality, and the speech recognition model version. Your application must handle this variability.
