Transcription services have now been around for long periods of time in one form of another just like written language to capture the essence of momentary speech. This is because transcriptions deal with the writing down of speech as it is happening. This however does not mean that the services have been as accurate and thorough as they have been the past couple of years.
Transcription was mostly done by hand before the introduction of reliable means of mechanical and note taking techniques. This means that people used pencils, pens and other manual writing tools. This should tell you something about the quality that was produced. It is quite obvious that writing is much slower than talking save for a few special cases. This means that when using long hand, it is quite impossible to write what someone is saying accurately.
At one time, this was solved by the creation of shorthand which is still used to date mainly when note taking and explicitly manual transcription is the only course of action that can be taken. People who practice short hand also suffer from the same problems as long hand in terms of speed and mechanical inefficiency.
Transcription however did not reach its full potential until the type writer was introduced in the market. This allowed a person to write much faster than short or long hand making it one of the most superior methods to capture speech back in the day. It however posed some problems when it jammed and needed to be refreshed so that it could work but all in all it was a really great invention. From here computers were discovered and they replaced the type writers as they were more efficient and flexible.
The ability to write mechanically however was not the greatest invention when it came to transcription. This is because recording of voices was. This however did not make an appearance until the seventies when the tape recorder could be used. This allowed individuals to record what someone had to say and play it back over and over again which was very useful for transcription services.
Despite the fact that there have been numerous technological advances that have helped with transcription services, it is important to make sure that you look for reliable and affordable companies that offer the services so that you can get quality work done on time. This is because it does not matter how great the technology is until the experts come up with software that can be used to automatically and accurately transcribe speech.
