There are a number of ways messages can be sent from Alexa's application. Alexa can deliver messages to a recipient's Alexa application, as well as to all supported Echo devices associated with their Amazon account. Alexa can send typed messages only from Alexa's app. If one sends a message from an associated Echo device, it transmits as a voice message. Alexa cannot send attachments such as videos and photos.
I have 3 Echo's and each one is now unplugged. If you go to the Alexa app and choose your device ---> settings and then history you'll find a long list of recordings the echo has made while secretly listening into your home. I had no idea this was happening and I find it very creepy. Nobody was using the wake word, etc. It just listened in and then recorded bits of conversation. I'm getting rid of them.
In the actual Settings section of this menu, you can customize your Alexa experience further. You can manage Amazon Shopping notifications, adjust what content you want in your daily flash briefing of the day’s headlines, and choose what sports teams you care about for your sports update. You can also enter in your home or work address to get traffic updates for your daily commute, and sync with your calendar (Gmail, Outlook, or iCloud) to know what’s up next on the day’s schedule.
The flash briefing skill submission process provides the steps to submit descriptive information about your skill and configure one or more feeds for each skill. You can then test your skill in your Alexa-enabled device and provide additional information about how you handle customer data and privacy. Once you've provided this information, you can submit your flash briefing skill for certification and use by customers.
From that point on, simply plug in the Echo device into a regular 110V. wall outlet, it comes with a plug in adapter. There are no batteries in this device, although some have them. A NOTE HERE" YES, YOU CAN UNPLUG IT WITHOUT IT LOSING ITS BRAINS AND REQUIRING REPEAT SET UP. So though not specified anywhere I read it evidently has some on board nonvolatile memory built in that will allow this. ( i spent several research sessions attempting to find this out, and finally had to bite the bullet and just try it. ) I moved it from one room location to another and within a few seconds it greeted me and said it was operational. NOW I AM ONLY AN OLD GUY WITH PRETTY GOOD HEARING ABILITIES YET, (NOT EXACTLY AN AUDIOPHILE ) BUT WITH DOLBY DIGITAL SOUND, THIS IS ONE NICE SOUNDING SPEAKER SYSTEM,
By default, Echo devices use “Alexa” as their wake word. While the device is constantly listening, it only starts tracking and analyzing what you say next after it hears “Alexa.” It then pulls up the relevant results. However, if, say, someone in your house is already named Alexa, you can change the wake word to something else: Amazon, Echo, or Computer.
