Voice control gives an ultrasound operator another way to request supported equipment actions. Its usefulness depends on the task, the command set and what happens when speech is missed or misunderstood. Evaluate the complete interaction: speak, confirm the response and continue the examination.
The clinician still positions the probe, obtains the required views and interprets the study within their training and responsibilities. Begin a product discussion by identifying whether “voice” means equipment control, report dictation or some separate analysis feature.
Separate three different functions
| Function | What it does | What to verify |
|---|---|---|
| Voice command | Requests an equipment action from a supported set. | Exact commands, availability, confirmation and fallback. |
| Dictation | Converts speech into text for documentation. | Text accuracy, review and correct patient association. |
| Image analysis or automation | Performs a specified analysis, measurement or workflow task on imaging data. | Its own intended use, evidence and required clinician review. |
These functions may appear in the same product while relying on different software and validation. Ask the representative to demonstrate each claimed function separately. The ability to recognize a spoken instruction establishes an input capability; diagnostic performance requires evidence about the relevant imaging task.
Use a documented example without assuming universal availability
GE demonstrated VoiceScan at the 2003 RSNA meeting. A later example is GE HealthCare's Hey Voluson feature, described for its Signature 20 and 18 systems. The 2024 U.S. clearance documentation identifies voice command among the features of those systems.
Those records identify a specific implementation. Obtain current regional labeling and the operator manual for the exact model, software release and installed options under consideration. Ask which languages, activation methods and microphone arrangements are supported. An older demonstration does not establish present support for an older unit.
Make a demonstration answer a work question
Choose a task where staff currently interrupt their normal hand position to use a control. Ask whether that task has a documented voice command, then compare the complete workflow in an approved nonclinical setting. Include the time needed to check the response and correct a mistake.
Record successful actions, missed commands, unintended responses and the operator's method of recovery. Use representative staff and realistic room conditions, including ordinary conversation and equipment noise. Agree local acceptance criteria before the demonstration so a polished single attempt does not decide the purchase.
Preserve confirmation and manual control
Ask how the operator recognizes that the system is listening, what response confirms an accepted command and how to cancel or recover. Staff need a familiar manual route when voice is unavailable or distracting. Include microphones and any accessories in the unit's approved cleaning and equipment-management process.
Training should cover the documented vocabulary and the situations in which the team chooses manual control. Report unexpected behavior through the institution's equipment-safety process. Keep demonstrations and configuration changes separate from ongoing patient examinations.
Clarify speech handling and continuing support
Ask where speech processing occurs, whether audio is stored or transmitted, what network access is needed and who can inspect retained data. Have the organization's privacy and security staff review the vendor's answers. The presence of a microphone leaves those data-handling questions open.
Record the accepted configuration and retest relevant tasks after changes to software, microphones, language settings or workflow. For an explanation of the examination itself, see the ultrasound guide. For patient communication and sensory needs during imaging, see planning a comfortable imaging appointment.
Keep a useful discussion record
Save the ultrasound voice control: demonstration and workflow record (editable text). Complete it with the responsible team and record unresolved questions as well as agreed decisions.
