While Siri and Alexa rely on a plethora of components and cloud servers to work out what people are saying, our brain can do it with a tiny area, researchers have revealed. We are able to distinguish Donald Trump's speech from the voice of our mother due to a section of the right posterior temporal lobe, one of the four major lobes in a mammalian brain, new research from a German university has found. Scientists have long disagreed on the exact area responsible for voice recognition, but they now believe it all takes place in a tiny area is known as the superior temporal gyrus (STG). These findings were supported by a previous study at MPI CBS, whereby, a phenomenon commonly known as'voice blindness', phonagnosia, the inability to recognize voices, was investigated. The two involved study participants - the only ones known in Germany to be affected by phonagnosia - were not able to identify people by voice, even their own mum or child.
