When you speak to Alexa, your voice is sent to Amazon's servers, where it is processed and analyzed. Amazon uses a variety of technologies to understand your voice, including automatic speech recognition (ASR) and natural language understanding (NLU).
ASR is the process of converting spoken words into text. Amazon's ASR system is able to understand a wide variety of accents and dialects. NLU is the process of understanding the meaning of words and phrases. Amazon's NLU system is able to understand a wide variety of commands and questions.
When you ask Alexa a question, it uses its ASR and NLU systems to process your voice and understand your request. It then uses its search engine to find the information you are looking for. If you ask Alexa to control a smart home device, it uses its device control API to send the appropriate command to the device.
Amazon stores your voice recordings in the cloud. This allows you to review your voice recordings and transcripts, and to delete them if you wish. Amazon also uses your voice recordings to improve its ASR and NLU systems.
