The Challenges of Traditional Medical Documentation
Healthcare needs accurate and timely documentation, but traditional methods present numerous challenges that affect patient care, provider productivity, and overall healthcare outcomes.
Decreased Face-to-Face Time with Patients
The burden of extensive documentation requirements often comes at the expense of quality patient interaction. Healthcare providers frequently divide their attention between the patient and their documentation duties, potentially compromising the patient-provider relationship and the quality of care delivered. Challenges here include the following:
Providers may rush through patient encounters to allocate time for documentation
Reduced eye contact and engagement during visits due to note-taking
Patients may feel neglected or undervalued when providers focus on paperwork

Time-Consuming and Tedious Process
One of the most pressing issues with traditional medical documentation is the sheer amount of time it consumes. Healthcare providers often spend hours each day manually entering patient data, writing clinical notes, and updating medical records, taking valuable attention away from direct patient care. Challenges here include the following:
Clinicians spend up to 50% of their workday on documentation tasks
Manual data entry is slow and prone to delays
Paperwork often extends beyond regular work hours, affecting work-life balance
High Risk of Errors and Inaccuracies
Manual documentation is inherently susceptible to errors, which can seriously affect patient safety and treatment efficacy due to time constraints, fatigue, or simple human oversight. Challenges here include the following:
Transcription errors can lead to misdiagnosis or improper treatment
Illegible handwriting may result in misinterpretation of orders or prescriptions
Incomplete or inconsistent documentation can compromise continuity of care
Inefficiencies and Delays in Medical Transcription
Medical transcription is the process of converting voice-recorded reports into written text. Traditional transcription processes introduce additional layers of complexity and the potential for delay.
The typical workflow entails dictation by the healthcare provider, then transcription by a medical transcriptionist, and finally review and sign-off by the provider. Challenges here include the following:
Turnaround time for transcribed documents can range from hours to days
Backlogs in transcription can delay critical decision-making and care coordination
The cost of employing or outsourcing transcription services can be substantial
How Speech-to-Text (STT) Works
STT models convert spoken language into written text. At its core, STT uses artificial intelligence (AI), specifically machine learning (ML) and natural language processing (NLP), to interpret and transcribe human speech.
The Technical Underpinnings of Speech-to-Text
Modern STT systems rely on complex algorithms and models for high accuracy and performance. Speech recognition has changed a lot, thanks to deep learning.
Neural networks, particularly deep learning models, are trained on massive amounts of data to recognize patterns in speech and accurately transcribe audio input into text output.
End-to-end models, which combine acoustic and language modeling into a single neural network, are becoming increasingly prevalent due to their superior performance. These models can learn directly from raw audio data and text transcripts, which simplifies the training process and improves overall accuracy.

One of the key advantages of modern STT systems is their ability to be trained on domain-specific data.
Since models can be fine-tuned to recognize medical terminology, jargon, language, and accents, they are more accurate than general-purpose models in healthcare.
How Deepgram's Nova 2 Medical Speech-to-Text (STT) Model Improves Healthcare Documentation
As you saw earlier, classical medical transcription is slow, error-prone, and delays critical documentation. Deepgram's Nova 2 Medical Speech-to-Text model addresses the unique challenges of medical transcription and voice-based healthcare applications.
Overview of Deepgram’s Nova 2 Medical STT Model
Deepgram's Nova 2 Medical is built on the industry-leading Nova 2 speech-to-text model—a Transformer-based STT model. The Transformer-based architecture is divided into two components:
Acoustic Transformer encodes audio into embeddings
Language Transformer decodes embeddings into text using input prompts
We have trained the model on large medical conversations and documentation datasets to understand complex medical terminology, clinical jargon, and diverse accents.

![](/_next/image?url=https%3A%2F%2Fwww.datocms-assets.com%2F96965%2F1721838881-stt-healthcare-4.png&w=3840&q=75)
Here are the key features and capabilities of Deepgram’s Nova 2 Medical STT Model:
Enhanced Medical Terminology Recognition
Nova 2 Medical has a 16% relative improvement in word recall rates (WRR) for medical terminology compared to the previous model, with an average relative WRR improvement of 20.5% vs. leading competitors.
WRR measures the percentage of words in the ground truth text that were correctly predicted or matched (i.e., true positives). The higher the WRR, the better the transcription is in terms of word accuracy.
This means the model makes fewer errors and has a more accurate representation of critical patient care details.
Superior Overall Accuracy
The Nova 2 Medical Model gets an 11% improvement in the overall word error rate (WER) for pre-recorded (batch) transcription, which is 42.8% better than the best alternatives in the medical field.
Typically, the lower the WER, the better the transcription is in terms of word accuracy. This translates to fewer manual corrections and more reliable documentation.
