Key differences
A clinical tool versus a speech engine
Dragon Medical One is made for clinicians. You speak and it types into the chart, with auto-punctuation, select-and-say voice commands, voice navigation and AutoText shortcuts that can be shared across users. Microsoft names workflows for Epic Haiku, Canto and Rover, Oracle Cerner PowerChart Touch and MEDITECH Expanse and MConnect, and says DMO has been Best in KLAS from 2021 to 2026. Soniox is a general speech AI company. Medical transcription is one listed use case, but its medical page says your application is responsible for mapping, validation, formatting and integration with the EHR. Most healthcare use of Soniox comes through software vendors that build on its API.
Price
The gap is large. As of November 2026, Soniox's API costs about $0.10 per audio hour for files and $0.12 for real-time, with speaker separation, language identification and formatting included. Its app has a free plan with weekly credits and a Pro plan at $19.99 a month, or $10 a month billed annually. Microsoft does not publish a DMO price. Reseller Speech Recognition Solutions lists $99 per user a month on a one-year contract, or $1,188 paid up front, plus a one-time $525 implementation fee that includes up to three hours of setup and training. For a developer, Soniox is far cheaper per hour. For a clinician, the right comparison is DMO against a finished product built on an engine like Soniox, not against the raw API.
Medical accuracy and vocabulary
DMO ships with a medical vocabulary and needs no voice profile training, according to Microsoft. Soniox relies on context you supply for each session, such as specialty terms, medication names and procedures. Its medical page shows a drug name recognized correctly once context is added, and it says transcripts should be reviewed before clinical use. Soniox publishes no medical accuracy figures beyond a customer testimonial, so test both with your own dictation.
Compliance and BAA
This is the main blocker for using Soniox directly with patient data. Soniox's security documentation lists SOC 2 Type 2, ISO/IEC 27001:2022, HIPAA and GDPR, says real-time audio is not stored, deletes async files after 30 days and never uses customer audio for training. But its medical page only says healthcare use may require a business associate agreement, and no page confirms Soniox signs one. Microsoft's DMO page does not list attestations or BAA terms either. Get a signed BAA from whichever vendor or reseller you buy from before sending PHI.
Product direction
Microsoft's DMO page now encourages customers to move to Dragon Copilot, which adds ambient note drafting to DMO dictation. Microsoft has not announced an end date for DMO, but buyers signing longer terms should ask about migration. Soniox is moving in a different direction, adding speech translation and text-to-speech to its API.
Which should you choose?
For most practices, Dragon Medical One is the practical choice because it works in the EHR without development. Soniox makes sense when you are building software, or for a clinician experimenting with low-cost voice typing outside of PHI until a BAA is in place.
Choose Soniox if:
- You are a developer or health tech company building dictation, transcription or a scribe
- You need real-time transcription across many languages at a low per-hour cost
- You can handle EHR integration, formatting and clinical review in your own product
Choose Dragon Medical One if:
- You are a clinician who dictates and wants voice commands and AutoTexts inside the EHR
- Your organization runs Epic, Oracle Cerner or MEDITECH
- You want an established medical dictation product and can commit to an annual term
Clinicians who want the note drafted from the visit rather than dictated can compare Microsoft Dragon Copilot or Freed, and developers who want a healthcare-specific speech SDK can look at Augnito.
