5. ALEXA IS AMAZON’S CLOUD-BASED VOICE SERVICE.
▸ Alexa can be accessed from either Amazon or 3rd Party
hardware or apps.
▸ Alexa is linked to one or more Amazon accounts.
▸ Echo is to Alexa as iPhone is to Siri
▸ Alexa is not really part of AWS

6. ALEXA IS A CONSUMER PRODUCT & BRAND
▸ Users know they’re talking to Alexa and they already have
a ‘relationship’ with her.
▸ Alexa knows who a user is as they have linked their device
to their amazon account.

7. ALEXA HAS SKILLS
▸ The Alexa service has a number of built in features, such as
shopping lists, jokes, alarms, general knowledge etc.
▸ 3rd parties can then create skills (apps) to provide
additional functionality on the Alexa platform
▸ Every Alexa device is able to access the full range of skills
▸ A skill doesn’t know which device accessed it just the user
account.
