So let's begin with the sounds easier to pronounce. The order may be as follows:
1) In pronouncing /p/ and /b/ the air passage is completely blocked by closing the lips and raising the soft palate; the air is compressed by pressure from the esophagus , and when the lips are opened the air suddenly escapes from the mouth, making an explosive sound. The difference between /p/ and /b/ is that the one is not voiced and the other is voiced.
