Speech to Text Medical Transcription Software
Admin / January 19, 2022
Electronic medical records (EMIs) refers to technology that integrates computers, software, and networks in an effort to reduce the costs of maintaining paper medical records. A key component of this technology is speech recognition software. Using advanced speech-to-text programs, doctors dictate notes on recording devices and later transcribe them into digital records.
Before tape recorders, doctors scribbled handwritten notes on paper when they met with patients. These notes then became part of massive repositories of paper, sticky notes and folders stored in file cabinets. Organization was limited, and without the help of computers, the medical staff had limited search capabilities. With the advent of audio recording devices, doctors began recording their notes on tape recorders. Assistants or secretaries later play these recordings and transcribe what they heard using typewriters. Word processors replace typewriters after the invention of personal computers.
Today's speech recognition software claims to have up to a 99 percent accuracy rate. Advances in software design, computer hardware, and digital signal processing allow clinicians to download most transcription tasks to computers. High-quality microphones also translate to higher speech recognition accuracy.
Microsoft includes a free text-to-speech program with Vista and Windows 7. It has a high accuracy rate and can be used by doctors for basic, non-critical documentation tasks. However, it doesn't claim to have the up-to-99 percent accuracy rate of Nuance Software's MedicalTra. This award-winning program is the world's most widely used medical transcription program, according to the manufacturer. It learns a user's speech patterns over time and updates its vocabulary database as users enter new words. MedicalTra has a vocabulary database that covers over 70 Categories and subject areas.
Doctors save time and money by using text-to-speech software. They no longer pay for transcription services or expect transcriptionists to listen to and transcribe long audio recordings. Patients also reap benefits because doctors are free to take detailed consultation notes without worrying about transcription costs.
Aside from the cost of software, clinicians should purchase high-quality sound cards and microphones for maximum speech recognition accuracy. They must also spend time learning how to use voice commands and training the software to recognize their voices. Even with proper training, transcription software cannot perform at a 100 percent accuracy level. According to a 2009 study by the Association for Health Care Documentation Integrity, medical documentation specialists discovered 1,200 more speech recognition errors in a sample of 823 dictations. Forty-three percent of the bugs were critical.
