//Limitations[edit]
Purchasing merchandise or digital media such as songs, by commanding Echo to buy the song, does require manual intervention—through an alternate user interface—to complete the purchase. Echo has demonstrated hit-or-miss results when asked common questions that users would expect better answers to. Echo sometimes confuses certain homophones.[27]
The current location of the device is set to Seattle (Amazon headquarters) by default and must be changed manually, but can only be set to a location within the USA. This is different from smartphone-based voice assistants that can get the actual location via built-in GPS locators. This restriction can lead to undesired or seemingly "wrong" results for questions that imply the location such as "What is the weather" (around here) or "Set an alarm for 10:00am" (local time here). There are several attempts to circumvent the USA only restriction, particularly by users in Europe and Australia. One such workaround is to set the Echo to a timezone that is exactly 12 hours difference from the local time. For example, if the current time in London is 11:30am, the user can set Echo to Hawaii Standard Time, which would be 11:30pm. This would enable Echo to report the correct time. There are two undesirable effects with using this method. One is the incorrect AM/PM notation and the second is the incorrect date. Another more sophisticated workaround is by manipulating the data that is transmitted and received by Amazon's servers as described by user "stonewater" on the unofficial Amazon Echo forum.[28] This method produces accurate and desirable results. However, it requires technological know-how with the aid of Request Maker for Chrome to accomplish the task.
Interaction and communication with Echo is currently only available in English.//
