Speech problems, also known as communication disorders, are a broad range of difficulties that can affect an individual's ability to communicate. One type of speech problem is lisps, which is a disorder characterized by the mispronunciation of certain sounds, usually s and z. 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 individuals learn to produce the correct sounds.
