Personal Assistants

Intelligent personal assistants which have their own hardware are sometimes referred to as smart speakers. These devices allow users to engage in two-way conversations with the device. Voice activated home automation and available "skills" allow users to quickly get hands-free answers. Device manufacturers employ software engineers and creative individuals to add canned responses, giving personal assistants personalities.
