Adult Speech Difficulties

Adult speech difficulties are common and come in many forms including stuttering, dysarthria, voice problems, and articulation difficulties. Often with speech therapy and some strategies many adults can improve their speech and communication skills.


There are a number of reasons speech difficulties occur in Adulthood:


Accident and injury

Unfortunately accidents happens, and these can lead to damage of the brain or speech muscles. Sometimes these things correct themselves naturally, but often there are long lasting effects. Checkout our Downloads section which has some fact-sheets with information and strategies to help a range of adult speech difficulties.


Disease and illness

Certain disease and illness can cause speech difficulties because of muscle or brain cell degeneration, but often there are many strategies that you can put in place to improve communication. Our section on Adult Acquired Difficulties will focus heavily on communication difficulties caused by disease such as Parkinsons and MS etc.  Also Check our Resource Centre for information and fact-sheets relating to improving communication following disease or illness.


Articulatory difficulties

“I’ve always had a speech problem” – some adults have had speech difficulties since childhood and the speech difficulty only became a problem when they reached adulthood. Some people might describe this as a “speech impediment”, “speech problem”, or a “pronunciation problem”. Sometimes it can be difficult to change some speech difficulties that have been present since childhood because they are so embedded. However, change is not impossible, and if you and your speech therapist / pathologist cannot “fix” the speech problem, there may be alternative strategies to help.



This is a motor speech disorder caused by a neurological injury or disease and it can affect one or more of the speech subsystems – respiration, phonation, resonance, prosody, articulation. When the part of the brain that controls speech production is damaged, the link from the brain to the muscles of speech is affected. Dysarthria can present in varying degrees of severity depending on localization and severity of brain damage. The production of speech sounds may be very difficult and in some cases speech may not be possible. The lips, tongue, palate, facial muscles, and the vocal folds (chords), may be uncoordinated or immobile. Further difficulties may occur if breathing is also affected as the lungs provide the energy for speech. An individual with dysarthria may have slurred, hoarse, jerky or strained speech and may be difficult to understand or completely unintelligible. Intelligibility may be further hindered by low volume, variable rate and rhythm, and irregular pitch. Brain injury causing dysarthria can be due to brain tumour, stroke, cerebral palsy, long term use of certain medications, or a degenerative diseases such as Parkinsons. Other co-occuring problems may include difficulties with swallowing and saliva control.  There are different types of Dysarthria depending on the area of and type of brain damage.  Treatment for dysarthria can be carried out by a speech and language therapist / pathologist and may involve strengthening or relaxing speech muscles, using compensatory techniques, or looking at assistive communication strategies or devices.  For a more detailed explanation of Dysarthria and the compensatory strategies can be found in the Dysarthria section, and a factsheet can be found in the Downloads section.


Dysfluency (Stammering or Stuttering)

Stammering has a major impact on the lives of adults. See our Adult Stuttering/Stammering section for more information.



Many adults experience voice problems for a range of reasons.  icommunicate has a section dedicated to adult voice problems with information, voice care tips and ideas to improve your voice. See our Voice Problems Section.


Assistive Technology (AAC)
There are now many new hi- and low-tech assistive communication devices that can help with a number of different speech and communication difficulties.  If you have a speech problem and are finding it hard to make yourself understood, you may find that an assistive device that has voice output, or where you can write messages, may help. In our Assistive Technology Section we discuss the use of assistive technology and lo-tech devices to facilitate communication. With the advent of new technology, this is becoming a major growth area for communication and communication difficulties. This website promotes communication and a total communication environment.  This means we focus on every modality that can be used to facilitate communication.


General tips to Make Speech More Understandable
There are many things you can do in your day to day life that will make you clearer and easier to understand.

  • Look at the person you are talking to.
  • Avoid communicating in noisy and distracting environments.
  • Slow down, and do not speak to quickly.
  • Make your sentences smaller between breaths.
  • Look forward, not down, when talking.
  • Use gesture and facial expression to enhance your message.
  • Use your lungs, and breathe from your diaphragm when talking to give your voice more power.
  • Follow conversational rules such as turn taking and staying on topic.
  • If you are having real problems being understood investigate other forms of communication such as writing your message, signing or using an electronic device to speak for you.


If you have concerns about your speech or voice, visit a qualified speech therapist /pathologist for assessment and speech therapy.
