The voice-elements component gives you easy access to the Web Speech API natively supported (as of this writing) only in Chrome. This lets you both read text aloud to the user, and perform basic voice recognition. Users can quickly tire of repetitive spoken prompts, but voice playback might useful for short alerts that incorporate dynamic content such as data coming from your app.
Likes: This supports multiple accents!
Dislikes: None of the other browsers — Firefox, Safari, and IE — currently support the Web Speech API. We still think components like this are an important indication of the sort of power that components can put in anyone's hand.
