How to Interrupt/ Stop Session

Hallo,

I connected rhasspy with node red via websocket.
In node red I build my “skills”.

I am now creating a timer/alarm clock.
At the end my flow is playing a alarm clock sound. I would like to send a stop intent to stop/interrupt the sound. But when my raspberry is playing the sound it isn’t listen to me and did not recognise the wake word.
I use porcupine for wakeword detection.

Has anybody an idea how to handle this?

What microphone do you use? Does it have acoustic echo cancellation?

If it does not (which seems to be the case), look on this forum for « AEC » and « acoustic echo cancellation » to learn more.

Hope this helps.

Thank you for your answer.

It is a good hint.
I have the Seeed Studio ReSpeaker 4-Mic Array for Raspberry Pi microphone.

I will give this ec https://github.com/voice-engine/ec a try.

Or do you have a better idea?

It’s either PulseAudio AEC module or Seeed VoiceEngine EC software.

Could you share your node-red flow for the alarm/timer? I am looking for something similar.

kind regards,
Hugo

Sure,

it is very basic programming. I would appreciate any feedback.
