I thought the same thing about speech recognition software until I became a stenographer. The thing about that software is that it can't decipher between heavy accents accuratley and it cannot format or put in punctuation.There is nothing that rivals the human brain. It is adept at being able to understand different accents, even heavy ones, and still not run into problems translating it into the written word. Plus, with software, recording devices, and computers there is a lot of room for mechanical malfunctions. I am not only able to record every word verbatim, but I also execute command functions that insert punctuation and format any numbers; such as social security, phone numbers, date of birth, driver's license, or dollar amounts with their correct hyphens or dashes so that when I print my transcript they are already formatted correctly. And with the more advanced machines, I can transmit what I am writing to up to 3 computers so that attorneys may view the proceedings live in what is called 'realtime translation'.
