Doppler's Futuristic Earbuds Sound Great. They Also Speak Spanish

AI-powered voice interfaces have given rise to a new class of devices competing to supplant our phones. There are friendly wireless speakers in our kitchens and helpful digital passengers in our cars. Among the most promising are in-ear computers--wireless earbuds that operate as always-on, voice-controlled Internet communication gateways. We humans already wear headphones everywhere, and in the long stretches when we're not barking at Siri, we're listening to music or podcasts. But if the idea of in-ear computers is going to take off, the companies that make them have to figure out what happens when you shut off Spotify.
