SEATTLE — Alexa has already made herself at home in kitchens and living rooms. Now Amazon is trying to get her in your ears. And on your face. And in your bathroom.

And maybe — someday — on your dog.

In a flurry of announcements on Wednesday, Amazon unveiled the latest additions to the growing list of products tied to the company’s Alexa voice assistant. The devices expand the options for places in the home where Amazon has already found success, while advancing the company’s hopes of getting Alexa to stay with users all day, everywhere they go.

The new products with Alexa built in include earbuds, glasses, a ring, and a tiny device for spaces like bathrooms and garages. A new dog collar tracks a pet so an owner can find its location with a smartphone.

To help keep devices connected to the internet, Amazon also unveiled Amazon Sidewalk, a low-bandwidth network that could connect smart devices across a city by piggybacking off neighbors’ devices.
