Performing the mental gymnastics of making the phoenetic distinction between words and phrases such as “I’m hear” to “I’m here” or “I can’t so but tons” to “I can’t sew buttons,” is familiar to anyone who has encountered autocorrected text messages, punny social media posts and the like. Although at first glance it may seem that phonetic similarity can only be quantified for audible words, this problem is often present in purely textual spaces.
