Any person of any age can develop aphasia, given that it is often caused by a traumatic injury. Nearly 180,000 people acquire the disorder every year in the US alone. Aphasia in the United States and Great BritainĪphasia affects about 2 million people in the US and 250,000 people in Great Britain. It is not a result of a more peripheral motor or sensory difficulty, such as paralysis affecting the speech muscles or a general hearing impairment. An individual's "language" is the socially shared set of rules as well as the thought processes that go behind verbalized speech. Aphasia is not caused by damage to the brain that results in motor or sensory deficits, which produces abnormal speech that is, aphasia is not related to the mechanics of speech but rather the individual's language cognition (although a person can have both problems, particularly if they suffered a hemorrhage that damaged a large area of the brain). With aphasia, one or more communication modalities in the brain have been damaged and are therefore functioning incorrectly. One prevalent deficit in the aphasias is anomia, which is a deficit in word finding ability. Aphasia also affects visual language, such as sign language. In contrast, the use of formulaic in everyday communication is often preserved. For example, while a person with aphasia, particularly Broca's aphasia, may not be able to ask a loved one when their birthday is, they may still be able to sing "Happy Birthday". The difficulties of people with aphasia can range from occasional trouble finding words, to losing the ability to speak, read, or write intelligence, however, is unaffected. Expressive language and receptive language can both be affected as well. The four communication modalities are auditory comprehension, verbal expression, reading and writing, and functional communication. To be diagnosed with aphasia, a person's speech or language must be significantly impaired in one (or several) of the four communication modalities following acquired brain injury or have significant decline over a short time period (progressive aphasia). Aphasia can also be caused by brain tumors, brain infections, and neurodegenerative diseases such as dementia. What is AphasiaĪphasia is an inability to comprehend or formulate language because of damage to specific brain regions. This damage is typically caused by a cerebral vascular accident (stroke), or head trauma. Pictograms that indicate daily activities and feelings help the user to assemble the phrases dictated by the narrator.Ī panel at the bottom of the screen contains common phrases that can be dictated directly by the narrator without typing. “I want to drink milk”, “Please call my doctor”, “I'm thirsty” and “Don't leave me alone” are among the phrases that were used during artificial neural network training. The Falante app uses an artificial neural network that runs on your device to suggest the next word to be entered by the user, according to the most common daily tasks performed by people who have difficulty speaking. If you use the online service, you can choose the voice that narrates the texts entered by the user. The Falante app can use text-to-speech conversion technology present on his device or an online service to accomplish this task. App Descriptionįalante is an iOS/Android app designed to help people who have difficulty communicating through speech (Expressive Aphasia), which usually occurs due to a stroke, brain injury, tumor, or other illness. I've learnt a lot in the process of making this app and would like to share some of this knowledge with you. I've created an iOS /Android app to help people with expressive aphasia to communicate better using some new technologies.
