Amazon first introduced Echo Spatial Perception (ESP) to its first-party Echo devices almost two years ago. ESP ensures that only the echo device closest to you in your home responds, and it is ideal if you have multiple echo devices. While Amazon has attempted to extend this feature to third party devices, most Alexa-enabled devices do not support ESP. Amazon changes it today and moves ESP to the cloud.
The change means that every Alexa enabled device can now support ESP without any software changes. Cloud-based ESP will also include improved accuracy for noisy environments, making Alexa more accurate on understanding commands and questions. The biggest advantage is that all Alexa enabled devices will now work together more intelligently in a multi-device environment.
While Amazon has solved this specific limitation for third-party Alexa devices, the company still has limitations on how multiple devices work together. Alerts, timers, and reminders are still limited to every Alexa device they are on, and we hope that Amazon is working on a more intelligent way to manage these on multiple devices.
