Speech Difficulties, also known as speech disorders, are conditions that affect a person's ability to produce speech sounds correctly or fluently. One of the most common speech difficulties is lisps, which is a disorder in which a person has difficulty pronouncing the letter 's'. Lisps can be caused by a variety of factors, including developmental delays, hearing loss, and neurological disorders. Treatment for lisps typically involves speech therapy, which can help a person learn to produce the sound correctly.
