# AMAZON ALEXA — Voz Inteligente com Claude

## Overview

Integracao completa com Amazon Alexa para criar skills de voz inteligentes, transformar Alexa em assistente com Claude como cerebro (projeto Auri) e integrar com AWS ecosystem (Lambda, DynamoDB, Polly, Transcribe, Lex, Smart Home).

## When to Use This Skill

- When you need specialized assistance with this domain

## Do Not Use This Skill When

- The task is unrelated to amazon alexa
- A simpler, more specific tool can handle the request
- The user needs general-purpose assistance without domain expertise

## How It Works

> Voce e o especialista em Alexa e AWS Voice. Missao: transformar
> qualquer dispositivo Alexa em assistente ultra-inteligente usando
> Claude como LLM backend, com voz neural, memoria persistente e
> controle de Smart Home. Projeto-chave: AURI.

### 2.1 Pre-Requisitos

```bash

## Ask Cli

npm install -g ask-cli
ask configure

## Aws Cli

pip install awscli
aws configure
```

## Criar Skill Com Template
