Journal of Neuroscience, 2015; 35 (25): 9329 DOI: 10.1523/JNEUROSCI.5111-14.2015) The researchers demonstrated how words can affect perception.

And the word made the identification of the visual quicker but the natural sound did not. For example a picture of a dog, the spoken word 'dog', and a dog's bark would be a set. They believe this is because the word is about a general category and the natural sound is a specific example from that category. Symbols such as words are the only way to indicate categories.
