Cough is used as an early symptom of various lung diseases and can be used to monitor the progress of a respiratory disease or infection. Since the COVID-19 pandemic, cough analysis has become popular for signs of early symptoms that can distinguish between COVID-19 and other types of cough.

However, in many cases the data is regional with high variance and large differences in quality, so the use of cough detection is still evolving. In general, analyzing an isolated cough has the advantage of allowing remote diagnosis and providing early evidence of a potentially more serious problem.

For countries with a small population, ICT technology can provide a large set of electronic tools that can improve the quality of life, and CoughAnalyzer aims at such a task. The CoughAnalyzer app is a mobile platform for capturing, storing and sharing cough recordings and analyzing them for medical and experimental use. CoughAnalyzer records the sounds of infectious patients without the risk of infection: the cough recording uses your personal mobile phone and the resulting recording is transmitted wirelessly to the doctor. 

The cough is recorded on the user's phone and can be commented on by the medical examiner or yourself. For cough annotation, the medical examiner receives the cough record and can immediately make a diagnosis. As a result, the patient may require immediate medical attention or travel to the hospital.

All annotated data are anonymized before being stored in the database in order to train useful algorithms. One of the most important tasks is the classification of cough and also the analysis of the user record. Two databases for training the classification.

The first database contains self-annotated coughs and the second database contains medical annotated records. Data collection creates voice databases with or without physician annotation. Classification, prediction, and annotation algorithms are trained to determine the best generalizations between medical data and self-annotated data. Such training allows the creation of inference systems that can be evaluated and modified as new records are added to the database.

Medicine and AI are coming together This project is based on the medical premise that cough, while only indicating possible respiratory health, can also be used to monitor symptoms of respiratory disease. Long-term records and records of various sizes are readily available to medical professionals and users alike, providing a powerful tool in medical diagnosis. The medical side is at the center of this project from several points of view. The application is designed to provide a digital tool for recording the cough of patients undergoing medical examination.

The application can also be used by a medical examiner to obtain information about a cough or a group of coughs. CoughAnalyzer allows the user to track the cough and send it to an external specialist. The application should serve as a medium to facilitate remote communication with medical professionals. Of course, the integration between the application and the doctor's specialties must be smooth: using the system must be natural for both the expert and the user.

Diagnostics, cough recording and storage, remote communication and data transfer are convenient, but usability must also be attractive: smartphones provide additional sensors that can be used in more reliable and cheaper diagnostics.

On the other hand, remote communication provides more work for medical researchers. Therefore, more reliable AI systems that provide more information and predictions to the medical researcher will reduce the work of medical experts. In particular, systems that can provide reliable symptom analysis or link data to health records.

Developing such systems requires expertise. Therefore, to provide more advanced and reliable devices for medical purposes, one of the most important areas is interface and integration. The interface should be particularly convenient and integrated with other devices and tools to make the application cheaper and more efficient than conventional tools.

Acceleration of technology diagnostics The acceleration of diagnostics has a huge impact on the medical industry. Early diagnosis saves time for doctors, hospitals and customers because they use only the right information when needed. Faster and cheaper reliable diagnostics also speed up recovery.

However, the information must be presented in a uniform way so that the medical professional can easily and quickly examine the data, recall previous records and display the time scale. Information that was not easy before An expert to assess the patient's condition. Cough Analyzer aims to be an international cough audio recording and analysis tool.

The general architecture is to collect coughs from different locations in the region and provide more general evidence of a particular disease. The medical field offers many opportunities for technology. From storage, security and privacy to remote surgery and drug development, the field of medicine has already benefited greatly from automation.
