🚀 Introduction

In this project, I built a voice-controlled AI agent that processes audio input, converts it into text, detects user intent, and performs actions such as file creation, code generation, summarization, and chat.

🧠 System Architecture

The system follows a simple pipeline:

Audio Input → Speech-to-Text → Intent Detection → Action Execution → UI Output

🔊 Speech-to-Text

I used OpenAI Whisper (local model) to convert audio into text. Whisper provides high accuracy even with different accents and noise.

🤖 Intent Detection

The system analyzes the transcribed text and classifies it into:

Create File
Write Code
Summarize Text
General Chat

⚙️ Actions
Based on the detected intent, the system performs:

File creation inside a safe output directory
Code generation and saving into files
Text summarization
Chat responses

💻 User Interface

I used Streamlit to build a simple and interactive UI that displays:

Transcribed text
Detected intent
Action results

⚡ Challenges Faced

Handling speech recognition errors
Managing file safety using a restricted output directory
Designing a clean UI pipeline

🎯 Conclusion

This project demonstrates how to build a local AI agent that integrates speech processing, NLP, and automation into a single system.
