Alexa Voice Control waits to "hear" a keyword. (e.g. "Alexa") which triggers active recording by the device. If it does not detect any keyword, the device continues to record sessions of a few seconds in a continuous cycle. All this happens locally in the device and nothing is sent to Bticino or third parties. Only if the keyword is detected does the device start recording and sending the audio to Amazon. Data management (privacy) is governed by the conditions reported on the Amazon.com website. Therefore, no processing of voice recordings is carried out by BTicino.
