Hacked and debloated an Echo Dot 2 (local LLM + local Speech recognition)

The GitHub repository "echo-dot-2-playground" by albertoZurini hosts experimental test scripts and tools for the Amazon Echo Dot 2, requiring users to first unlock and root their device. It includes scripts for device I/O testing, debloating, and a custom local voice assistant stack replacing Amazon's cloud services, featuring wake-word detection, speech-to-text using Sherpa-ONNX, and a local LLM engine called llama-server. Proprietary Amazon APKs and libraries are not included and must be extracted by users themselves. The project supports automated testing, manual ADB command testing, and focuses on privacy by enabling offline voice assistant functionality on the Echo Dot 2.
