Alexas voice assistant can become confused when a childs voice is similar to an adults and end up playing inappropriate media or giving out incorrect information if not set up properly.
The question is, how did you know? The loudness or intensity of a sound is measured in decibels (dB) with 0 dB being the average intensity of a sound that can just barely be heard by a young human. Over thousands of years of evolution, countless breeds of dogs have made up an entirely new species. WebIt is considered safe for human hearing and there is no recommendation for limiting your exposure to this dB level if you are an adult. Unsurprisingly, the areas of activation are focused on the temporal lobe (though most likely there was a lot of activation elsewhere as well, this is just where they were looking), where there is a lot of auditory processing. - "Sleeplessness"
