Why internal microphones are not supported input devices for Dragon Medical

Dragon Medical products are not optimized for use with internal or built-in microphones, for example, array microphones integrated into laptops and tablets. Currently, internal microphones do not meet the audio quality requirements for Dragon Medical.

This is because most internal microphones have a very different audio signature and would require a unique acoustic model to compensate for two (2) general deficiencies:

  • The average distance between the speaker’s mouth and an internal microphone is greater than that distance for a purposed input device used for recording high-quality speech. Dragon Medical would have to severely compensate for the ambient audio (background noise) and low signal-to-noise ratio.
  • Internal microphones are inherently of lesser design quality and materials.

Using Internal microphones with poor audio quality always result in recognition accuracy issues with Dragon Medical and an inferior experience for the healthcare provider.

This is an area that Nuance is currently researching for a future Dragon Medical release. We recommend using the headset or PowerMic II supplied with your Dragon Medical product which is distinctly purposed to provide high-quality speech recognition.

Additionally, please see the link below where Nuance maintains a Hardware Compatibility list for certified devices to work with your Dragon Medical product.
