Common speech changes include soft volume, hoarse or breathy voice, slurred speech, speaking too fast or in a monotone, repeating sounds like stammering, and having to repeat yourself often. You might also pause before starting words or avoid social situations due to speech difficulties. Parkinson's can affect sensory processing, so you may not accurately perceive how loud your voice actually is. You might feel like you're speaking at normal volume when others find it difficult to hear you. This is why external feedback from others is often needed. Parkinson's is progressive, so speech changes may worsen gradually. However, speech therapy can help you learn strategies to maintain clearer communication and slow the progression of speech difficulties. Early intervention often leads to better outcomes. Speech therapy can help improve voice loudness and clarity, teach techniques to control repetitive sounds, provide articulation exercises, and for severe cases, introduce alternative communication methods like alphabet boards or voice output devices.
