To wake up the voice assistant a wake word is necessary. There are several engines to be able to react to a wake word. Raven is the wake word engine we used in our project. After the self-selected wake word has been detected, a command can be spoken.
- Easy setup
- Only three wake word templates need to be set
- Easy to configure
- Good precision with 3-4 syllables long words
- Wake word should not be too short
- A wake word should not sound like common words
