The key benefits are improved efficiencies; accomplishing more in less time. Even if you type over 85 words per minute, using speech recognition is much faster in terms of transcribing speech to text but also for controlling your computer through voice commands.
Transcription of dictation from a digital voice recorder is also accomplished much faster than its analogue predecessor. As time is money, the return on investment in either of these technologies is pronounced.
Value added in text creation is also demonstrable when using speech recognition, particularly in email and notations. Most individuals find that speaking is far easier than typing and therefore more thorough and detailed information is provided when using speech recognition over manually typing. For our medical and legal clients, this is a very noticeable boon.
Independence and self-reliance is also quite clear, as users of these technologies quickly discover how much documentation they can perform themselves without relying on support staff, which is not always available when needed most.
