How do I enable voice command to interrupt playback?

I ask for your help in setting up the interruption of playback using a wake word.

I have added the Alexa wake word and enabled various settings in the menu related to noise suppression, but none of this is working.

There is already a piece of code for this, but the condition doesn't trigger no matter what I try.

I changed the code for this section:

        case kDeviceStateSpeaking:
            display->SetStatus(Lang::Strings::SPEAKING);

            if (listening_mode_ != kListeningModeRealtime) {
                audio_service_.EnableVoiceProcessing(false);
                // Only AFE wake word can be detected in speaking mode
                audio_service_.EnableWakeWordDetection(audio_service_.IsAfeWakeWord());
            }
            audio_service_.ResetDecoder();
            break;

However, it does work like this, but I have to shout very loudly.

        case kDeviceStateSpeaking:
            display->SetStatus(Lang::Strings::SPEAKING);
            audio_service_.EnableVoiceProcessing(false);
            audio_service_.EnableWakeWordDetection(true);
            audio_service_.ResetDecoder();
            break

Could you share how you configured interruption by voice command?

Try to use the wake word "Alexa" to interrupt the AI speaking.

If you have to shout very loudly, it's because AEC is not enabled for your device and the speaker is to loud.
You can set a very low volume and test if it performs better.

AEC available boards:

1. Boards using BoxAudioCodec like ESP-BOX-3, Lichuang Dev Board S3
2. Boards using ES8388 or ES8389 audio codecs

You're absolutely right; I was thinking along those lines too. If I lower the volume, I can interrupt the wake-up wave without having to scream, just like when waking up. I have an ESP32-S3-1.54-MUMA, so even though I have it in software, my device doesn't support AEC in hardware because it's not on your list.

May be you know another way to do it (remote interrupt playback, without pushing buttons)

It is challenging to implement voice interruption without AEC. If you are receiving data from the MIC, the overwhelmingly loud speaker will drown out all other voices.
