Hi there! I see your Echo Dot isn’t recognizing voice commands. Let’s work together to get it responding properly again. To start, could you tell me a little more about what’s happening? For example:

- Does the Echo Dot light up or show any indicator when you speak?
- Have you noticed if the microphone button might be muted (usually indicated by a red ring)?
- Is the Echo Dot connected to Wi-Fi and powered on as usual?
- Have you tried restarting the device or the network?

This info will help me guide you better. Meanwhile, here’s a straightforward step you can try first:

1. Unplug your Echo Dot from the power outlet.
2. Wait for about 30 seconds to clear any temporary glitches.
3. Plug it back in and wait for the light ring to turn solid blue.
4. Try speaking a voice command once it’s fully booted.

This simple reboot often resolves issues with unresponsiveness4.

If the problem persists after this, we can move on to checking the microphone mute button, ensuring Alexa is using the correct wake word, and verifying your Wi-Fi connection. Let me know what you find!
