+# Voice Assistant Bridge (Docker Backend)
+
+This repository contains the backend infrastructure for the local Voice Assistant system. It acts as the middleware between the ESP32 audio stream and Home Assistant.
+
+## 🏗️ Architecture
+
+```mermaid
+graph LR
+    ESP32[ESP32 Hardware] -->|MQTT Audio Stream| Bridge
+    Bridge[Python Bridge] -->|HTTP Request| Whisper[Faster-Whisper Container]
+    Whisper -->|Text| Bridge
+    Bridge -->|MQTT Text Command| HA[Home Assistant]
+    Bridge -->|MQTT Status| ESP32
+```
+
+## 🧩 Components
+
+### 1. `docker-compose.yml`
+Orchestrates two containers:
+*   **`voice-bridge`**: The logic handler. Listens to MQTT audio, buffers it, detects Wake Words via `OpenWakeWord`, and handles routing.
+*   **`whisper-api`**: A lightweight Flask API wrapping `faster-whisper` for Speech-to-Text conversion.
+
+### 2. `mqtt_audio_bridge.py`
+The main Python script running inside the `voice-bridge` container.
+*   **Input:** Listens to raw PCM audio on `voice/audio_stream` (Broker .13).
+*   **Processing:**
+    *   Uses **OpenWakeWord** to detect "Hey Jarvis".
+    *   Buffers audio and sends to Whisper API.
+    *   Safety mechanisms (Memory limits, Log rotation).
+*   **Output:** Publishes transcribed text to `homeassistant/voice/text` (Broker .30).
+
+### 3. `app.py`
+The Whisper API endpoint.
+*   **Model:** `small.en` (Optimized for CPU usage with `int8` quantization).
+*   **Language:** Locked to English to prevent hallucinations on static/silence.
+
+## 🚀 Deployment
+
+1.  **Requirements:** Docker & Docker Compose.
+2.  **Configuration:** Update IP addresses in `mqtt_audio_bridge.py` for your MQTT brokers.
+3.  **Run:**
+    ```bash
+    docker compose up -d
+    ```
+
+## 🔧 Debugging
+
+**View Logs:**
+```bash
+docker compose logs -f voice_bridge
+```
+
+**Restart Stack:**
+```bash
+docker compose restart
+```

+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:

+
+AnyIO is an asynchronous networking and concurrency library that works on top of either asyncio_ or
+Trio_. It implements Trio-like `structured concurrency`_ (SC) on top of asyncio and works in harmony
+with the native SC of Trio itself.
+
+Applications and libraries written against AnyIO's API will run unmodified on either asyncio_ or
+Trio_. AnyIO can also be adopted into a library or application incrementally – bit by bit, no full
+refactoring necessary. It will blend in with the native libraries of your chosen backend.
+
+To find out why you might want to use AnyIO's APIs instead of asyncio's, you can read about it
+`here <https://anyio.readthedocs.io/en/stable/why.html>`_.

+
+Features
+--------
+
+AnyIO offers the following functionality:
+
+* Task groups (nurseries_ in trio terminology)
+* High-level networking (TCP, UDP and UNIX sockets)
+
+  * `Happy eyeballs`_ algorithm for TCP connections (more robust than that of asyncio on Python
+    3.8)
+  * async/await style UDP sockets (unlike asyncio where you still have to use Transports and
+    Protocols)
+
+* A versatile API for byte streams and object streams
+* Inter-task synchronization and communication (locks, conditions, events, semaphores, object
+  streams)
+* Worker threads
+* Subprocesses
+* Subinterpreter support for code parallelization (on Python 3.13 and later)
+* Asynchronous file I/O (using worker threads)
+* Signal handling
+* Asynchronous version of the functools_ module
+
+AnyIO also comes with its own pytest_ plugin which also supports asynchronous fixtures.
+It even works with the popular Hypothesis_ library.
