A cautionary tale: Echo starts recording when it hears the "wake" word ('Alexa' or 'Amazon'), but it can mistake other words or parts of speech for a wake word (for example, consider how close the phrase "he likes her" is to "Alexa"). Browsing through the history I have found snippets of conversations that Echo had no business listening to, and which the recorded subjects certainly did not wish to send to Amazon.
