Signs You or a Loved One May Need Speech Therapy After a Stroke

Published: July 2026 | By Megan Williamson, MA, CCC-SLP

After a stroke, so much is happening at once. Medical appointments, rehabilitation, paperwork, family adjustments — and in the middle of all of it, you may be noticing changes in how your loved one communicates. Maybe they're struggling to find words. Maybe their speech sounds different than it used to. Maybe they seem to not understand what's being said to them.

This post is about recognition — learning to identify the signs that speech therapy is needed after a stroke. Not everyone who has a stroke will need speech therapy. But many do, and too often families wait months (or years) before connecting with a speech-language pathologist. Understanding what to look for can help you act sooner — and that matters, because timing is one of the most important factors in stroke communication recovery.

10 Signs That Speech Therapy May Be Needed After a Stroke

1. Trouble Finding Words — Even Simple Ones

One of the most universal early signs of a communication disorder after stroke is word-finding difficulty. Your loved one may stop mid-sentence looking for a word, use a wrong word in its place ("chair" instead of "table"), say "thing" or "that" when they can't retrieve the right noun, or describe something at length because they can't name it directly.

Clinically, this is called anomia — difficulty retrieving words — and it is one of the most common symptoms of aphasia. It is different from normal tip-of-the-tongue moments; post-stroke word-finding difficulty is more frequent, more disruptive, and not resolved by "giving it a few seconds."

2. Slurred or Slow Speech

If your loved one's speech sounds slurred, mumbled, or like they have marbles in their mouth, this is a sign of dysarthria — a motor speech disorder caused by weakness or reduced coordination in the muscles of the lips, tongue, jaw, and throat. Dysarthria is not a language problem; it's a physical problem with speech production. But it can significantly reduce intelligibility and communication effectiveness.

You might notice: speech that sounds "thick" or imprecise, difficulty being understood on the phone, a voice that sounds strained or breathy, or speech that trails off as if the person runs out of energy mid-sentence.

3. Speaking in Very Short Phrases or Single Words

If someone who used to speak in full, fluent sentences is now producing only short, effortful phrases — "Want water," "Yes, good," "Go now" — this is a sign of expressive aphasia. The grammar and sentence structure of language has been disrupted by the stroke. The person knows what they want to communicate; the injury has affected their ability to put it into full sentences.

This can be subtle at first — especially if the person can still answer yes/no questions and handle simple conversations. But in more complex communication situations, the limitation becomes apparent.

4. Difficulty Understanding What You're Saying

Not all strokes affect the ability to speak. Some primarily affect comprehension — the ability to understand language. Signs of comprehension difficulty include: following along with a conversation but responding off-topic, nodding as if they understand when they actually don't, becoming confused when multiple instructions are given at once, and difficulty following the plot of a TV show or a phone conversation.

Comprehension difficulties can be easy to miss — especially if the person is socially skilled enough to mask confusion, or if family members fill in the gaps without realizing they're doing it. A speech-language pathologist can assess comprehension systematically and identify exactly where breakdowns are occurring.

5. Reading and Writing Problems

Aphasia doesn't just affect spoken language — it can affect reading and writing too. If your loved one is struggling to read a newspaper they used to read daily, making spelling errors they never made before, unable to sign their name, or having difficulty writing even simple messages, these are meaningful signs of language disruption that warrant a speech therapy evaluation.

Literacy — the ability to read and write — is deeply connected to independence, identity, and quality of life. It affects the ability to read medical paperwork, write grocery lists, communicate by text, and engage with the broader world. Aphasia therapy directly addresses reading and writing as well as spoken communication.

6. Substituting Wrong Words or Making Up Words

If your loved one says "apple" when they mean "door," or produces words that aren't real words at all (called neologisms), this is a classic sign of Wernicke's aphasia. The person is trying to communicate — their speech flows fluently and they don't appear to be struggling — but the content of what they say doesn't match what they intend to express.

This can be alarming for families. It may seem like the person is confused or disoriented — but they're not. It's a language retrieval problem, not a cognitive one. A speech-language pathologist can explain exactly what's happening and develop a treatment plan.

7. Coughing, Choking, or Struggling During Meals

Swallowing problems after stroke — called dysphagia — are often overlooked because families don't connect swallowing with speech therapy. But swallowing is directly within the scope of speech-language pathology, and it is a critical safety concern after stroke.

Signs of post-stroke dysphagia include: coughing or choking during meals, food or liquid "going down the wrong way," a wet or gurgling voice quality after eating, unexplained respiratory infections or pneumonia, painful swallowing, avoidance of certain foods or textures, and taking a very long time to finish meals. If you notice any of these, a swallowing evaluation is urgent — aspiration pneumonia is one of the leading causes of rehospitalization after stroke.

8. Frustration, Withdrawal, or Avoiding Conversations

Communication breakdown is emotionally exhausting. If your loved one seems increasingly frustrated during conversations, avoids social situations they used to enjoy, refuses to talk on the phone, or appears to be withdrawing into themselves — this is often a sign that communication is harder than it looks from the outside.

People with aphasia often develop sophisticated strategies for hiding or minimizing their communication difficulties. Nodding along, staying quiet, laughing when others laugh, leaving the room — all of these can mask a significant underlying communication impairment. The frustration and withdrawal you're noticing are important clues.

9. Memory and Attention Changes Affecting Communication

Some strokes affect the cognitive systems that underlie communication — attention, memory, organization, and reasoning — without causing aphasia directly. If your loved one loses their train of thought mid-sentence, has difficulty staying on topic, cannot follow multi-step instructions, or struggles to plan and execute a phone call, these may be signs of cognitive-communication disorder.

Cognitive-communication disorders are also within the scope of speech-language pathology. A comprehensive evaluation can identify whether the communication difficulties are primarily linguistic (aphasia) or cognitive (cognitive-communication disorder) — or both — and guide treatment accordingly.

10. A Voice That Sounds Different Than Before

Changes in voice quality — a hoarse, breathy, strained, or weak voice after stroke — can indicate damage to the nerves controlling the vocal cords or the muscles of the larynx. Voice changes after stroke warrant evaluation by a speech-language pathologist, who can assess laryngeal function and determine whether voice therapy or a referral to an otolaryngologist (ENT) is indicated.

When to Call: A Note on Urgency

If your loved one is in the acute phase of stroke recovery — still in the hospital or a rehabilitation facility — speech therapy evaluation should begin immediately. Most acute care and inpatient rehabilitation facilities have speech-language pathologists on staff. Ask the medical team directly: "Has a speech therapist evaluated them?"

Once discharged, do not wait to see whether things "go back to normal on their own." Some spontaneous recovery does occur in the first weeks post-stroke — but the window of peak neuroplasticity is short. Research consistently shows that early, intensive speech therapy produces meaningfully better outcomes than delayed treatment.

If you are reading this weeks or months after the stroke and your loved one never received outpatient speech therapy, it is not too late. The brain retains capacity for change beyond the acute recovery window. Gains are still possible — and a speech-language pathologist can help you understand what's realistic and build a plan.

What Happens If You Wait?

Many families delay seeking speech therapy for understandable reasons: they're managing everything else, they're waiting to see how things progress on their own, they're not sure whether the changes are significant enough, or they're not sure where to turn. But delayed intervention has real costs:

• The window of peak neuroplasticity closes, making change harder to drive
• Communication compensations and avoidance strategies become entrenched, which can slow progress later
• Swallowing problems left untreated can lead to aspiration pneumonia, weight loss, and dehydration
• The emotional and social consequences of communication breakdown deepen over time
• Family members develop their own compensatory patterns that, while well-intentioned, may reduce the person's opportunity to practice and improve

None of this is meant to alarm you — it's meant to empower you to act. A phone call to a speech-language pathologist costs nothing. An evaluation can clarify what you're seeing and give you a path forward.

Frequently Asked Questions

Do I need a doctor's referral to see a speech therapist?

In Utah, you can contact a speech-language pathologist directly without a physician referral. We can evaluate your loved one and then coordinate with your medical team as needed. That said, some insurance plans do require a referral for coverage — it's worth checking your plan before your first visit.

My loved one already did speech therapy in the hospital — do they still need it?

Possibly yes. Hospital-based speech therapy during the acute phase focuses on immediate stabilization and basic functional communication. Outpatient therapy — which is more intensive, more individualized, and longer-term — is often where the most meaningful communication gains happen. If it's been weeks since discharge and no outpatient speech therapy has started, please call us.

How do I know if the communication changes are stroke-related or something else?

A speech-language pathologist can evaluate and help clarify the nature and cause of communication changes. We also coordinate with physicians when additional medical evaluation (such as neuroimaging) may be helpful. Don't try to diagnose this on your own — a professional evaluation is the right first step.
