Alexa triggers itself (herself) when playing audio · alexa-pi/AlexaPi#74

2016-11-05T14:25:13.000Z

So this thing ... My thoughts / observations: 1. Sometimes it happens for an obvious reason like when she's talking about herself. 2. Sometimes it happens even when she doesn't say her name. 3. Snowboy might be more accurate and could solve (2). 4. Possible solutions: 1. Disable listening when playing stuff - stupid. 2. Do some sort of sound cancellation - oh man, this wouldn't be easy. This would depend on each specific device - we would probably need some calibration. And how exactly would we get the output audio? Syncing with the played file doesn't sound easy. Should playback_handlers provide interface for this? People have various operating systems and sound backends - this would be a nightmare to support all. PulseAudio has output monitors that could probably be used for this, I don't know. Your ideas?

So this thing ...

My thoughts / observations:

技術スタック: python
領域: backend
Issue 種別: bug
難度: 5
推定時間: over 1 week
活動状況: stale
明確さ: needs investigation
前提条件: なし
初心者向け度: 10
調査方針: This issue involves preventing Alexa from being triggered by its own audio output. Research possible approaches such as implementing echo cancellation, using Snowboy's better wake word detection, or disabling listening during playback. The repository description indicates no active development, so any solution would need to be self contained. Consider examining the audio playback and recording modules in the codebase to understand current architecture.
