Description
Summary:When listeners misperceive words in noise, do they report words that are more common? Lexical frequency differences between misperceived and target words in English and Spanish were examined for five masker types. Misperceptions had a higher lexical frequency in the presence of pure energetic maskers, but frequency effects were reduced or absent for informational maskers. The tendency to report more common words increased with the degree of energetic masking, suggesting that uncertainty about segment identity provides a role for lexical frequency. However, acoustic-phonetic information from an informational masker may additionally constrain lexical choice.
