Accepting verbal communication to include the content, as well as the delivery of your message, then stuttering can affect both. The content, including the main idea, words you choose, and organization structure you use will only be affected if you let it. If you’re distracted from what you want to share by your negative thoughts and perceptions of your stuttering, the clarity of your content can be compromised. Rather, if you are focused on getting your message across, your content will be in your full control. In addition to content, there is delivery-- the speech sounds, volume, pitch and overall melody of your voice. Stuttering tends to impact the way you produce sounds, with certain sounds taking longer to realize, and others coming out more than once. Since the sounds themselves stay much the same, intelligibility tends to be at 100%.
