Ask HN: How does Alexa avoid interrupting itself when saying its own name?
I've noticed that Alexa doesn't interrupt itself when it says "Alexa," but it does respond when someone else says it. How does it achieve this? Here are a few questions I have:
Self-Recognition: How does Alexa distinguish between its own voice and a user's voice saying "Alexa"?
Voice Characteristics: What specific features (e.g., pitch, tone) does Alexa analyze to recognize its own TTS voice?
Algorithms and Models: What machine learning models or algorithms are used to handle this task effectively?
Implementation: Are there any open-source libraries or best practices for developing a similar functionality?
Any insights or resources would be greatly appreciated. Thanks!
