A speech therapist is someone who has one to two years of postgraduate training. They specialize in speech function and swallowing function. They are used most frequently after someone has had a stroke or head injury or after a serious illness when someone has been on prolonged ventilatory support. As one grows older, vocal cords can become less elastic and larynx muscles can weaken, making it difficult to talk in a manner they are accustomed to.RelevanceRecovering speech after a stroke is possible, especially if treatment is started immediately. Speech therapy for seniors can help them re-learn how to speak, using vocal exercises to help them communicate effectively once again.
