On-device wake-word ('hands-free') detection in iOS

Scowld has a hands-free mode: say the companion's name and it starts recording. The wake detection runs on-device using the Speech framework, and nothing is sent anywhere until a command actually starts recording.

The UX lesson: a good wake word makes a voice app feel like a conversation instead of a walkie-talkie. The tradeoffs (false triggers, missed phrases) are real and documented.
