What is an acoustic lexical neighborhood?

An acoustic lexical neighborhood refers specifically to groups of words that have similar acoustic-phonetic characteristics. This concept is grounded in the way that various words can sound alike, especially in terms of their phonetic structure. For example, words that differ by only one sound, such as "bat" and "pat," belong to the same lexical neighborhood because they share a high degree of phonetic similarity.

This similarity can influence speech perception, as similar-sounding words can compete with one another during the recognition process, creating challenges for individuals with hearing impairments or other communication difficulties. Recognizing acoustic neighborhoods is important in fields like audiology and speech-language pathology, as it can help professionals design therapeutic strategies and interventions for individuals who may struggle with distinguishing between similar-sounding words.

Options that focus on visual patterns, mispronunciations, or distinct meanings do not capture the essence of what an acoustic lexical neighborhood is, which is fundamentally based on the sound characteristics of words rather than their meanings or visual representations.
