Insulin Bolus Calculator with Automatic Speech Recognition

There is a recommendation regarding diabetes treatment with insulin pens or pumps that elevated blood glucose concentration after meal should be compensated by insulin bolus. This requires effective estimation of food carbohydrates and performing arithmetic calculations, what may be challenging tasks for many persons with diabetes. Consequently, their glycemic control is poor with glycated hemoglobin level higher than recommended. When this state lasts too long, it directly leads to microvascular and macrovascular diabetes complications. Microvascular complications include retinopathy leading to blindness, nephropathy leading to renal failure and neuropathy leading to diabetic foot disorders leading to amputation. Macrovascular complications include cardiovascular diseases, strokes and serious reduction in blood flow rate to legs. Good metabolic control in diabetes delays the onset and progression of diabetes complications. Some help may assure insulin bolus calculators. They must be safe, effective and easy to use. The developed VoiceDiab system helps users in estimation of insulin dose based on voice description of a meal. It consists of smartphone application and MS Windows servers working with developed linguistic database and nutrient database. The system calculates the insulin dosage for insulin pen or pump users. The system automatically suggests a dual-wave bolus, if there is significant amount of proteins and fats in a meal. The outpatient clinic study revealed that patients supported by the system or those unsupported had comparable means and variabilities of blood glucose concentration. The inpatient clinic trial showed that the VoiceDiab system was able to properly estimate insulin boluses compensating meals based on the voice description of these meals.
