Thank you for your response. You pose a great question! To answer this question, we to first ask the question: What does "low frequency of words' imply? Answer: According to above research study, it implies: "*Word frequency refers to how often a word occurs in a language. Words with higher frequencies are more easily accessed because they are more often encountered. Words with lower frequencies put increased* ***demand*** *on speech production. The phonological encoding required to produce a lower frequency word is less familiar to the speaker making it more taxing, therefore more vulnerable to stuttering events*" Conclusion: So, low frequency words are not popular words.. words that we don't often use in our language. In this context, it doesn't relate to the (faster or slower) rate of speech. It has more to do with.. that unpopular words "trigger" stuttering more often. And thus, we should address this "trigger" - to desensitize (or unlink from the primary symptom of stuttering, aka the basal ganglia underactivation of the direct and indirect pathways). That's the long answer, in my own words. The short answer, in my opinion, is that a helpful intervention could be, to learn to (1) ignore, or (2) build tolerance for, such triggers (in this case, unpopular words that trigger stuttering). I hope that answers your question
