chosen.content: Amazon Alexa is powered by the technology from Amazon's Alexa Voice Service (AVS). AVS provides an interactive voice-controlled software service that powers devices such as Amazon Echo. It uses audio-based recognition technology to detect spoken commands, then processes the data and responds back out loud. Alexa uses speech recognition, natural language understanding, and adaptive speech algorithms to process the data. These algorithms can detect even subtle differences in word pronunciation, and can respond accurately even when there are multiple people speaking or when noise is present. Alexa also continuously refreshes its understanding of user's preferences as it adapts to its environment and new situations.

rejected.content: The technology that powers Amazon Alexa comes from a variety of sources. At its core is the Amazon Device Voice Runtime, or AVS, which is the software that powers the voice recognition and natural language processing (NLP) capabilities. Additionally, Amazon Alexa relies on a combination of cloud services, AI, and machine learning, as well as numerous API integrations with other services and products. Amazon Alexa also utilizes advanced data processing, including deep learning and neural networks, to provide enhanced capabilities such as complex prediction and classification. Finally, Amazon Alexa is enabled by a large array of sensors, including a multi-mic array, motion sensors, an array of ultrasonic detectors, and optical sensors.
