Ambient Voice Technology vs Medical Speech Recognition: what’s the difference?

Voice technology has been used in healthcare for decades, helping clinicians create letters, notes and other patient records more efficiently. But the arrival of Ambient Voice Technology (AVT) introduces a fundamentally different way of using speech within the clinical workflow.

While both technologies work with spoken language, the key difference is simple: medical speech recognition generally requires the clinician to dictate; AVT can listen to the natural clinician-patient conversation and create structured draft notes from it.

Medical speech recognition: the clinician dictates

Traditional medical dictation involves a clinician deliberately recording notes or letters, either during or after a consultation. Those dictated notes may then be transcribed by a secretary or transcription team.

Medical speech recognition changes that process by using speech-to-text technology to convert the clinician’s words directly into written text.

Purpose-built clinical speech recognition and healthcare speech recognition systems are designed to recognise medical terminology and support the way healthcare professionals work. Instead of typing a letter or consultation note, the clinician can dictate it and review the resulting text.

This makes medical speech recognition particularly useful for tasks such as creating dictated letters, reports and updating the clinical record. Modern medical dictation software can significantly reduce manual typing while allowing clinicians to retain control over exactly what is being recorded.

Ambient Voice Technology: the consultation becomes the starting point

AVT works differently; rather than requiring the clinician to dictate a note separately, AVT can listen to the natural patient conversation taking place during a consultation. It can distinguish relevant information from the wider conversation, interpret its context and use that information to create structured notes for clinician review.

That changes the starting point. With clinical dictation, the clinician decides what needs to be recorded and speaks it specifically for transcription. With AVT, the consultation itself provides the source material from which draft consultation notes can be produced.

NHS England has published guidance on the use of AI-enabled ambient scribing products in health and care settings, reflecting the growing interest in how this technology can be introduced appropriately within healthcare.

Importantly, AVT-generated outputs should still be reviewed and approved by the clinician before being added to the patient record. The technology can support the creation of the draft, but the clinician retains responsibility for checking that the resulting record accurately reflects the consultation.

Medical speech recognition and AVT compared

It’s about workflow, not simply transcription

AVT is not simply a faster form of speech recognition. Rather than only converting spoken words into text, it can interpret the context of a natural consultation and create structured draft outputs for the clinician to review. This means the two technologies support different parts of the document creation process.

Medical speech recognition remains extremely effective when a clinician wants to dictate a specific letter, report or clinical note. AVT is designed for situations where capturing the consultation itself can reduce the administrative work associated with producing consultation notes.

They should therefore be viewed as complementary technologies rather than one simply replacing the other.

How does AVT fit into existing NHS workflows?

For NHS organisations considering voice technology, the question is not necessarily “Which technology is better?” but “Which approach is right for this particular clinical workflow?” In some settings, established medical speech recognition will remain the most appropriate choice. In others, AVT may offer an opportunity to reduce the administrative work associated with producing consultation notes.
