" summary

Amazon Alexa works by local wake-word + beamforming to capture audio, sending recordings to cloud STT and NLU that map speech to defined intents and slots; skill backends can run anywhere via HTTPS or AWS Lambda and are developed with tools like the ASK CLI and SDK. There are about 30,000 skills, built-in SSML and audio support, and monetization/account-linking options; the platform gives a free tier (the first million requests free) and developer tooling (simulator, cards, slots, date/number normalization) that demonstrably power real skills.
