Yes, multiple sclerosis does affect speech in up to 70% of people living with the condition. These changes can range from mild voice clarity issues to more noticeable slurring and word-finding difficulties that impact daily conversations.
If you’ve noticed changes in how you or a loved one speaks since an MS diagnosis, you’re not alone. We understand how concerning and isolating these communication challenges can feel. Let’s explore what’s happening, why it occurs, and most importantly, what we can do about it.
Key Takeaways
IN THIS ARTICLE
- Speech changes are common in MS, affecting up to 70% of people with the condition – ranging from mild slurring and voice clarity issues to more significant word-finding difficulties that can fluctuate with fatigue and stress levels.
- Two main types of speech disorders occur: dysarthria (muscle control problems) and dysphasia (word-finding difficulties) – with dysarthria being more common and directly linked to nerve damage affecting the muscles we use for speaking.
- MS affects speech by damaging myelin, the protective coating around nerves – creating lesions in brain areas that control mouth, tongue, throat, and vocal cord muscles, disrupting smooth communication between our brain and speaking muscles.
- Speech therapy and early intervention significantly improve outcomes – personalized treatment plans including breathing exercises, articulation drills, and pacing strategies help maintain and improve communication abilities throughout the MS journey.
How Multiple Sclerosis Changes Our Speech
When we think about MS symptoms, we often focus on mobility or vision changes. However, multiple sclerosis affects speech by damaging the protective coating around nerves that control our speaking muscles. This process, called demyelination, disrupts the smooth communication between our brain and the muscles we use to talk.
The areas of our brain responsible for speech coordination become affected when MS creates lesions in these critical regions. Think of it like static on a phone line – the message is there, but it doesn’t come through as clearly as it should.
What’s Really Happening Inside
Multiple sclerosis is an autoimmune condition where our immune system mistakenly attacks myelin, the protective sheath around nerve fibers in our central nervous system. When this myelin becomes damaged, nerve signals slow down or get disrupted entirely.
These disruptions create plaques or lesions in our brain and spinal cord. When lesions form in areas controlling our mouth, tongue, throat, and vocal cords, we start experiencing speech changes. The lack of coordination between our nerves and muscles leads to the communication difficulties many of us face.
The Two Main Types of Speech Disorders in MS
We see two primary speech-related challenges in multiple sclerosis: dysarthria and dysphasia. Understanding which type you’re experiencing helps determine the best approach for managing symptoms.
Dysarthria: When Muscles Don’t Cooperate
Dysarthria occurs when the muscles that help produce speech become weak or difficult to control. This is the more common speech disorder we see in MS, directly linked to physical changes in brain areas that control muscle movement.
People with dysarthria often describe their speech as:
- Slurred or mumbled
- Slower than usual
- Quieter or harder to hear
- Sounding flat or robotic
The frustrating part about dysarthria is how it can fluctuate. During MS flare-ups, speech difficulties often worsen, while remission periods may bring noticeable improvement.
Dysphasia: When Words Won’t Come
Dysphasia, sometimes called aphasia, affects our language and word-finding abilities rather than just muscle control. While less common in MS, this condition creates its own unique challenges.
With dysphasia, we might struggle with:
- Recalling the right word mid-sentence
- Constructing sentences that make sense
- Understanding what others are saying
- Organizing thoughts into coherent speech
Both conditions can significantly impact our daily interactions and shake our confidence in social situations.
Common Speech Symptoms We Experience
Speech changes in MS vary widely from person to person, but certain patterns emerge consistently across our community. The most frequent symptoms include slurred words, slower speech patterns, and changes in voice quality.
Recognizing the Signs
Many of us first notice our speech becoming more nasal or monotone. Others experience changes in pitch or volume that make conversations challenging. Some common experiences include:
- Words running together unexpectedly
- Choppy or uneven rhythm when speaking
- Strange pauses in the middle of sentences
- Difficulty getting words out, especially when tired
- Speech that becomes less clear during stressful moments
Fatigue plays a huge role in worsening these symptoms. Many of us find that our speech is clearest in the morning and becomes more difficult as the day progresses.
What is MS tongue?
MS tongue refers to symptoms affecting the muscles of the tongue, which are caused by lesions in the central nervous system.
These lesions can make the tongue feel numb or cause a tingling sensation, known as paresthesia. Some people also notice twitching, stiffness, or weakness in their tongue muscles.
These problems can lead to less precise tongue movement, making speech sound blurred or slurred.
Coordination needed for clear speech is affected, especially when saying certain sounds or words quickly. Eating and talking at the same time may also become harder.
MS tongue may come and go if the lesions are temporary. In other cases, the problem may get worse over time, especially if muscle stiffness or weakness increases.
Primary Speech Disorders We Face
Living with Dysarthria
Dysarthria affects many of us with MS when nerve damage impacts the muscles we use for speaking. These muscles may become weak, tight, or spastic, making our speech harder for others to understand.
The experience varies significantly among individuals. Some describe feeling like they’re speaking through cotton, while others compare it to trying to talk with a numb mouth after dental work. The voice might sound flat, lacking the natural melody and rhythm of normal speech.
Movement of our mouth, lips, and tongue becomes challenging, affecting pronunciation. What’s particularly frustrating is how dysarthria can worsen during relapses and improve during stable periods, making it unpredictable.
Dealing with Dysphonia
Dysphonia is a voice disorder affecting many people with MS, caused by nerve or muscle changes that impact vocal cord function. Our voice may sound weak, hoarse, or strained, sometimes becoming breathy or harsh.
Changes in volume control become noticeable – some days we can barely speak above a whisper, while other times our voice might sound unnaturally loud or shaky. Voice breaks and tremors can make phone conversations particularly challenging.
Like other MS symptoms, dysphonia fluctuates with our overall condition, often worsening during fatigue or relapses.
Related Symptoms That Affect Our Communication
Multiple sclerosis creates a cascade of symptoms that can indirectly impact how we communicate. Understanding these connections helps us develop comprehensive management strategies.
MS Tongue: When Our Tongue Won’t Cooperate
MS tongue refers to symptoms affecting tongue muscles caused by central nervous system lesions. Our tongue might feel numb, tingly, or experience that pins-and-needles sensation called paresthesia.
Some of us notice twitching, stiffness, or weakness in our tongue muscles. These changes make precise tongue movements difficult, causing speech to sound blurred or slurred. Eating and talking simultaneously becomes challenging, and certain sounds or quick words become nearly impossible to pronounce clearly.
Swallowing Difficulties and Their Impact
Swallowing problems, medically called dysphagia, often accompany speech difficulties in MS. When MS affects nerves controlling mouth and throat muscles, both swallowing and speaking become compromised.
These muscles serve double duty – they help us eat safely and contribute to clear speech. When they’re weakened or uncoordinated, we might experience:
- Coughing or choking while eating or drinking
- Food or liquid going down the wrong way
- Avoiding certain foods due to swallowing fears
- Reduced speech clarity due to muscle weakness
The connection between swallowing and speech means that addressing one often helps improve the other.
Cognitive Changes and Communication
Cognitive impairment affects many of us with MS and significantly impacts communication abilities. Problems with attention, memory, and word-finding create additional layers of communication challenges.
We might struggle to remember specific words mid-conversation, lose our train of thought while speaking, or find it difficult to process information quickly enough to respond naturally. This can lead to:
- Long pauses while searching for words
- Mispronouncing familiar words
- Difficulty following conversations in noisy environments
- Frustration during social interactions
How Fatigue Affects Our Speech
Fatigue is one of the most common MS symptoms, and it significantly impacts speech clarity. When we’re tired, words become slurred, our voice grows softer, and speech may sound monotone.
Muscle weakness in our lips, tongue, and throat becomes more pronounced with fatigue. Controlling voice volume and maintaining steady speaking pace becomes increasingly difficult as the day progresses. These problems often worsen after physical activity or during particularly stressful periods.
Getting an Accurate Diagnosis
Diagnosing speech issues in MS requires careful evaluation because symptoms can resemble other conditions. Accurate diagnosis helps doctors create the most effective treatment plan while ruling out other potential causes.
The Evaluation Process
Speech-language pathologists typically begin with comprehensive assessments that include:
- Listening carefully to speech patterns and quality
- Testing for specific types of speech disorders
- Evaluating muscle strength and coordination
- Assessing cognitive factors that might affect communication
The evaluation might include repeating words, naming objects, reading aloud, or having conversations. Memory and attention tests help determine if cognitive issues contribute to speech difficulties.
Role of Medical Testing
MRI scans help identify MS lesions in brain areas that control speech. These images show doctors exactly where damage has occurred and help predict which speech functions might be affected.
Additional tests like evoked potentials measure how well nerves carry signals to and from the brain, revealing if speech-related nerve pathways are functioning properly.
Treatment Options and Speech Therapy
The good news is that targeted interventions can significantly improve communication abilities for people with MS. Speech therapy, combined with other treatments, offers hope for maintaining and improving communication skills.
Comprehensive Rehabilitation Approaches
Effective treatment typically involves a team approach including speech-language pathologists, neurologists, and sometimes physical therapists. This collaborative effort addresses multiple aspects of communication difficulties simultaneously.
Personalized exercise programs help strengthen muscles involved in talking and swallowing. Daily oral motor exercises, breath control practice, and posture improvement all contribute to clearer speech production.
Medical treatments like corticosteroids or disease-modifying therapies may help reduce relapses that worsen speech symptoms, providing additional support for rehabilitation efforts.
Specific Speech Therapy Techniques
Speech therapists develop individualized plans based on each person’s specific challenges and goals. Therapy techniques include articulation drills for clarity, breathing exercises for sustained speech, and pacing strategies for better organization.
Common therapeutic approaches include:
- Over-articulation exercises to improve clarity
- Voice strengthening techniques
- Rhythm and pacing training
- Compensatory strategies for difficult sounds
- Alternative communication methods when needed
Many therapists also teach family members and caregivers how to support communication at home, creating a comprehensive support system.
Factors That Influence Speech Outcomes
Several factors determine how MS affects our speech and how well we respond to treatment. Understanding these influences helps set realistic expectations and optimize management strategies.
MS Type and Progression Patterns
People with relapsing-remitting MS often experience speech issues that come and go, improving between relapses. In contrast, those with progressive forms typically face steady or gradually worsening speech problems over time.
Research shows that 40-51% of people with MS develop dysarthria, with symptoms varying based on lesion location and MS type. Those experiencing frequent or severe relapses are more likely to notice significant speech effects.
Environmental and Genetic Influences
Both genetic and environmental factors play roles in how severely MS affects speech. Certain genetic patterns may increase the risk of developing severe communication challenges.
Environmental factors like vitamin D deficiency, frequent infections, high stress levels, poor nutrition, and smoking can all negatively impact MS symptoms, including speech difficulties. Maintaining healthy lifestyle choices may help delay or reduce the severity of speech problems.
Long-Term Management and Prognosis
Long-term speech outcomes depend heavily on early intervention and consistent management strategies. Disease-modifying therapies may reduce relapses and slow progression of speech difficulties when started early.
Regular speech therapy sessions, combined with home practice and family support, often yield the best results. Creating a strong support network among healthcare providers, therapists, and loved ones ensures ongoing monitoring and intervention when new symptoms appear.
Living Well with MS-Related Speech Changes
While speech changes can be challenging, many people with MS successfully adapt and maintain meaningful communication throughout their journey with the condition. The key lies in early recognition, appropriate treatment, and ongoing support from healthcare professionals and loved ones.
Understanding that speech difficulties are a common part of MS helps reduce the isolation and frustration many feel. With proper management, most people can maintain effective communication and continue participating fully in their personal and professional lives.
Remember, you’re not alone in facing these challenges. Speech therapists, support groups, and the broader MS community offer resources, understanding, and practical strategies for managing communication changes effectively.
If you’re experiencing speech changes, don’t wait to seek help. Early intervention often leads to better outcomes and can help preserve communication abilities for years to come.

Frequently Asked Questions About MS and Speech
Multiple sclerosis can change the way a person speaks and communicates. It may affect voice strength, clarity, and make it harder to find the right words or swallow safely.
How does MS impact communication abilities?
MS can damage areas in the brain that control both speech and language. This can result in slow, slurred, or uneven speech and may make it harder to organize thoughts or find words for conversation. Some people may also develop changes in the tone or quality of their voice.
At what stage does MS affect speech?
Speech problems can appear at any point in MS. However, they are more common in those with advanced MS or during a relapse. People with mild MS might not notice any speech issues for years.
Can multiple sclerosis lead to difficulties in swallowing?
Yes, MS can affect swallowing in addition to speech. Damage to the nerves controlling mouth and throat muscles can lead to choking or coughing while eating or drinking. About a third of people with MS experience some degree of swallowing trouble according to research.
Does MS make it hard to talk?
MS can make talking difficult if the muscles needed for speech are weakened or not working together well. This can cause slurred speech, speaking softly, or having a nasal or harsh-sounding voice. Some people may also have trouble speaking for long periods.
What is MS tongue?
“MS tongue” is not a medical term but can refer to a heavy or clumsy-feeling tongue. This may lead to trouble pronouncing words clearly or moving the tongue as needed for speech.
Is slurred speech a common symptom of MS?
Slurred speech, or dysarthria, is a common symptom in MS, especially during flare-ups or in later stages. It happens when the muscles controlling speech become weak or uncoordinated as discussed by the MS Trust.
What role does speech therapy play in managing MS-related speech issues?
Speech therapists help people with MS speak more clearly, use their voice better, and practice safe swallowing. Therapy can teach breathing techniques, exercises for mouth and throat muscles, and alternative ways to communicate if speech is very difficult.
Do voice changes typically occur with multiple sclerosis?
Voice changes are possible with MS. A person may notice their voice is softer, more hoarse, or sounds nasal. These changes happen because MS affects the nerves controlling the vocal cords and the muscles used for speech, as described by the MS Society.
What forms of dysarthria are associated with multiple sclerosis?
People with MS can experience different forms of dysarthria. The speech might be slow, slurred, monotone, or have uneven rhythm and pitch. Sometimes, speech is broken up with long pauses between words or syllables due to poor control of breathing and mouth muscles, as explained in clinical reviews.
