Problems with how you speak can be a symptom of multiple sclerosis for some people. MS speech disorders include slurring of speech and problems with the quality of your voice (dysarthria) and difficulty remembering specific words (dysphasia).
A speech and language therapist may be involved in helping you cope with speech problems.
What are speech problems?
Speech problems may happen at any stage of MS. For most people they are relatively mild and manageable. Symptoms may be worse during a relapse or in the more advanced stages of the condition. However, the impact of any changes in speech will be very individual. For example, a mild difficulty could have a large effect on you at work. Or a larger change might not have so much impact on you if you tend to speak with fewer people who know you well.
The most common changes in speech and communication in MS include:
- slurring of speech
- problems with volume, strength or quality of your voice
- weakness of the chest muscles, making breathing and speech harder
- difficulty remembering specific words
- difficulty following longer or more complex conversations.
People with more advanced MS may find that the rhythm and intonation of their speech are disrupted, perhaps causing them to sound ‘robotic’. This is sometimes referred to as scanning speech.
What causes speech problems?
Speech disorders in multiple sclerosis can be caused by weakness or lack of coordination in the muscles used in speaking. This is called dysarthria. Speech problems can also result from weakness of the chest muscles, affecting breathing and the production of breath to speak with.
Speaking involves several parts of the body that need to work together. This includes the lungs, diaphragm, vocal cords, lips, tongue and nasal cavity.
What can I do if I have speech problems?
- Try to speak slowly and regularly. Try to keep sentences short.
- If possible, try to plan to have important conversations when you are feeling least tired, as fatigue can make communication more difficult.
- Make the most of non-speech aspects of communication like facial expression, gesture and even referring to photos, written things or objects
- Using email or texts might be easier than speaking to someone on the phone when speech is difficult
- Check with your listener that they understand what you're saying. If there are problems, this can avoid misunderstandings.
- Plan and support more complex conversations by making written notes and referring to them

What treatments are there for speech problems?
Depending on the nature of your problems, the speech and language therapist may:
- work through strategies to improve speech, such as talking more slowly or concentrating on what you are saying
- help you with exercises to improve the quality of your voice - the volume or the clarity of what you say. This might involve exercises with how you form words or with how you breathe when talking.
- help you find the right tools to support your communication . There is a range of possible technology, which includes amplifiers to make your voice louder and software to convert written information into speech.
- help you and people you talk with most often to implement changes to compensate for difficulties. Suggestion may include making sure you are face to face, reducing background noise and introducing the main topic before giving lots of detail.
- work with you and the rest of your MS team to help you manage the effects of fatigue on your communication
A physiotherapist might work with you to strengthen your chest muscles to improve your breath control and increase your lung volume. They may suggest the use of a cough assist device to do this. This device may also help to clear your lungs of persistent secretions and reduce the risk of chest infection.
