A High-Fidelity Digital Extension of Human Identity
ECHOME is an elite, open-source framework designed to clone and automate a user's cognitive and behavioral identity across three fundamental pillars: Mind, Voice, and Action. Built for the modern AI/ML engineer, it provides a 100% local, zero-cost, and private-by-default alternative to cloud-based personality and agent systems.
ECHOME transitions from a high-precision psychometric assessment into a Jarvis-grade autonomous intelligence layer. It doesn't just assist; it mirrors your decision patterns, communication style, and technical judgment.
A high-fidelity Computerized Adaptive Testing (CAT) system built on Graded Response Models (GRM).
- Dimensionality: Maps 8 scientific dimensions including Big Five (OCEAN), Cognitive Style, and Lifestyle patterns.
- Optimization: Uses Fisher Information maximization to reduce assessment length by 70% while maintaining 90%+ confidence (Standard Error < 0.32).
- Estimation: Employs Maximum A Posteriori (MAP) estimation to stabilize latent trait (Theta) recovery.
A custom, local pipeline for zero-shot speaker replication.
- Capture: Uses Whisper (Local) for ASR.
- Cloning: Extracts a 256-dim d-vector vocal fingerprint via Resemblyzer.
- Synthesis: Employs XTTSv2 and HiFi-GAN for high-fidelity, low-latency 22kHz audio generation.
An autonomous orchestration layer using LangGraph and a 3-tier memory system.
- Orchestration: Multi-agent routing via LangGraph for complex task execution.
- Memory (CoALA): Persistent Episodic, Semantic, and Procedural memory stored in a local Qdrant vector database.
- Specialists: Dedicated agents for Bash execution, Python REPL, and technical architecture analysis.
