+<summary><strong>Optional (Acoustic Echo Cancellation) </strong></summary>
+
+This optional configuration support the use AEC and require either a working PipeWire-Pulse or PulseAudio backend.
+
+Enable the echo cancel PulseAudio module:
+
+```bash
+pactl load-module module-echo-cancel \
+  aec_method=webrtc \
+  aec_args="analog_gain_control=1 digital_gain_control=1 noise_suppression=1"
+```
+
+If successfully loaded you will see an ID presented after the command. Keep this ID as you may need it to "tune" the AEC.
+
+```bash
+pactl load-module module-echo-cancel \
+  aec_method=webrtc \
+  aec_args="analog_gain_control=1 digital_gain_control=1 noise_suppression=1"
+536870916
+```
+
+Determine the names of the echo cancellation audio devices. On my system it is "Echo-Cancel Source" and "pipewire/echo-cancel-sink":
+
+```bash

+**Edit LVA config.json file:**
+
+```bash
+nano ~/linux-voice-assistant/linux_voice_assistant/config.json
+```
+
+**Add AEC configuration entries to LVA config.json file:**
+
+```bash
+  "audio": {
+    "input_device": "Echo-Cancel Source",
+    "input_block_size": 1024,
+    "output_device": "pipewire/echo-cancel-sink"
+  }
+```
+
+**Example (LVA config.json file with MQTT, Grove Port, and AEC enabled)**
+***Note: Change the source and sink values to match your system!***
+
+```bash
+{
+  "app": {
+    "name": "Linux Voice Assistant"
