Comparing Voice Input Tools for Electronic Medical Records: Choosing by SOAP Auto-Generation, Pricing, and Integration
Share this article

As a means of reducing the burden of chart input, attention to "voice input" for electronic medical records is growing. While it can increase the time physicians spend facing patients and greatly reduce the effort of record-keeping, the real capability differs greatly by tool. This article compares voice input tools for EMRs along three axes—"SOAP auto-generation, pricing, and integration"—and explains a recommended way to choose and the checkpoints that help you avoid mistakes.

There are two types of voice input for electronic medical records

Even though we say "voice input" in one breath, there are broadly two types.

  • The "transcription type," which merely turns speech into text: It converts spoken words into text as-is. A person shapes the chart.
  • The "SOAP auto-generation type," which creates a chart draft from conversation: The AI understands the consultation conversation or voice memos and automatically assembles even a chart draft in SOAP format.

What has drawn attention in recent years is the latter. Because it not only turns speech into text but organizes it into the structure of Subjective (S), Objective (O), Assessment (A), and Plan (P), the physician's editing work is greatly reduced. When comparing, first determine which type you are looking for.

Comparison axis 1: The accuracy of SOAP auto-generation

What most affects the value of a voice input tool is the accuracy of SOAP auto-generation. Check the following points.

  • Support for medical and technical terms: Whether it can correctly recognize the technical terms and abbreviations of each department.
  • Ability to organize spoken language: Whether it can accurately extract only the key points from conversation that includes small talk and rephrasing.
  • Shaping into SOAP structure: Whether it sorts content into appropriate items, rather than being a mere transcription.
  • Ease of editing: Whether the UI makes it easy for the physician to confirm and correct the draft the AI generated.

Because accuracy also changes depending on the department and way of speaking, it is recommended, if possible, to try scenes close to your clinic's care in a demo or trial.

Comparison axis 2: Pricing structure

The pricing of voice input tools differs greatly by how they are provided.

TypePricing tendencyCharacteristics
Standard in the EMROften included in the chart usage feeEasy to keep additional costs down / already integrated
An option of the EMRAn added monthly chargeCan add the function to an existing chart
A standalone external toolMonthly charge as a separate serviceIntegration with the chart is required separately

When comparing, it is important to judge on a total basis—not just the monthly fee, but whether charges are based on usage counts or number of physicians, initial cost, and even the "integration cost" described below.

Comparison axis 3: Integration with the electronic medical record

What is surprisingly often overlooked is "how the generated chart draft is reflected into the EMR."

When using a standalone external tool, the effort of copying and pasting the text created from voice into the EMR remains, and the hard-won efficiency can be halved. The ideal is a form in which the voice input function is built into the EMR and the generated SOAP draft is reflected directly into the chart.

In particular, with a product where voice input works integrated with the EMR and receipt computer, the recorded content is also linked to billing data, connecting everything from input to claims smoothly.

The security check you must not forget

Voice input handles extremely sensitive information—conversations with patients. In selecting a tool, always confirm the following.

  • Compliance with the guidelines on the safe management of medical information systems (the "3 Ministries, 2 Guidelines").
  • Whether the design ensures that conversation data and input content are not used for AI training without permission.
  • The security structure, such as encryption of communications and data storage location.

Summary of the recommended way to choose

Choosing a voice input tool for an EMR is less likely to fail if you choose in the following order.

  1. Decide the type you want (transcription type or SOAP auto-generation type).
  2. Verify the accuracy of SOAP auto-generation in your clinic's care with a demo or trial.
  3. Compare pricing on a total-cost basis (including integration cost).
  4. Confirm whether reflection into the EMR is smooth (integrated or bolted-on).
  5. Confirm security and guideline compliance.

"AI Karte": integrated from voice input to rezept checking

Pottech's "AI Karte" is an AI-native product that builds automatic SOAP generation via voice input into the EMR as standard. It automatically generates a chart draft in SOAP format from the consultation conversation, and the generated content is directly linked to the chart and billing data. There is no copy-and-paste effort as with external tools, and because it further supports missed billing and return risk with AI rezept checking, it can streamline everything from input to claims end to end.

In closing

The key to avoiding mistakes with a voice input tool for an EMR is to compare along three axes: "the accuracy of SOAP auto-generation," "pricing," and "integration with the chart." Even something that looks like a standalone transcription tool, when evaluated including integration and security, often shows that a product working integrated with the EMR leads to more comprehensive efficiency.

Through the provision of AI Karte, Pottech serves as the optimal business partner for clinics—supporting not only better working conditions for physicians, nurses, and medical clerical staff, but also helping clinics achieve to the fullest what they want to accomplish.
