Speech disorder

A speech disorder or speech impairment is a long-lasting communication problem, caused by problems with speaking. People with speech impairments have problems making certain sounds, forming words, or combining these words into sentences. Common speech impairments are stuttering, lisps and rhotacism (inability or difficulty pronouncing the R sound). Someone who cannot speak at all is called mute.^[1]
