Amazon has integrated its voice assistant, Alexa, with a large language model designed to enhance its capabilities in managing smart homes. This integration aims to improve Alexa’s understanding of conversational phrases, enhance contextual interpretation, and enable the execution of multiple tasks from a single command. However, in the future, some of Alexa’s functions may become paid services.

Alexa’s Large Language Model (LLM) significantly differs from the platforms underlying chatbots like Bard and ChatGPT; it is optimized for voice assistants and smart home management, according to Dave Limp, Senior Vice President at Amazon Devices and Services. The need for significant changes in the voice assistant market has been apparent for some time. While they held great promise when introduced a decade ago, innovation in this field has been slow and incremental. The breakthrough may come with generative artificial intelligence.

Following the release of ChatGPT, tech giants like Microsoft and Google raced to integrate generative AI into most of their services, but they encountered challenges along the way. Therefore, Amazon is taking a cautious approach, especially since Alexa LLM is directly connected to smart homes. It will be gradually introduced as part of a preview program over several months, initially available to users in the United States. Users can apply through their voice assistant by saying, “Alexa, let’s chat.”

Considering the advanced capabilities promised by generative AI for voice assistants, the platform will not remain free indefinitely. In its current form, it will remain free, clarified Dave Limp, but a “superhuman” voice assistant capable of performing complex tasks will become a paid service. Initially, Alexa will improve its understanding of user commands, eliminating the need for extreme specificity. Having to repeat words or assign unique names to smart home devices has been a common source of frustration with voice assistants.

Users will be able to tell the new Alexa that they’re cold, and it will adjust the temperature on the climate control system accordingly. With a command like “Alexa, light this room in Seahawk colors,” the AI will determine the colors of Seahawk helicopters, identify the room’s location, and make the appropriate API requests. The large language model supports over two hundred smart home API endpoints, which, combined with the context of the conversation and the list of smart devices, will enable more efficient control.

Generative AI will help Alexa interpret sequences of commands within a single phrase, allowing users to create scenarios without configuring them in an app. Dave Limp provided an example of a regular scenario he uses at home: “Alexa, every morning at 8 am, turn on the lights and play music in the child’s bedroom to wake him up, and in the kitchen, start the coffee maker.” Such complex scenarios immediately appear in the app as regular commands. Initially, multi-command functionality will work with only a subset of smart home devices, but the list is expected to expand in the future.

Developers of compatible third-party devices will also be able to leverage Alexa’s cognitive functions using tools like Dynamic Controller and Action Controller. These tools will help them issue commands that are not part of the basic voice assistant’s set of commands. For instance, Dynamic Controller will allow the setting of predefined lighting schemes. With multi-color GE Cync bulbs installed in a room, you can give a command like “Alexa, make it look spooky here,” and the system will correctly interpret it without requiring additional setup. Action Controller will assist the voice assistant in responding correctly to statements like “Alexa, the floor is dirty,” prompting a robot vacuum to take action. Amazon noted that companies such as GE Cync, Philips, GE Appliances, iRobot, Roborock, and Xiaomi have already expressed interest in these tools, with more developers expected to join the program in the future.

Integrating the large language model into Alexa is just the beginning of a new phase in the voice assistant’s development. Amazon aims to simplify everyday tasks for users, but further plans have not yet been disclosed.
