Yes. The Nasality Microphone is widely used with children, including in school-based programmes and university clinic settings. The lightweight acoustic separator is designed to comfortably fit different facial contours. The NasalanceViewer software includes gamified displays — including a Skywriter game — that work well when taking nasalance measurements from younger speakers. The device has been used in peer-reviewed research with paediatric populations across multiple countries.

Both instruments measure nasalance using an acoustic separator positioned above the upper lip. The primary differences are portability, cost, and ease of use.

The Nasality Microphone is a handheld, USB-powered device that connects to any Windows laptop or tablet and is significantly more affordable than the PENTAX Nasometer. The Nasality Microphone requires no calibration, since the nasal and oral microphones are individually matched during the manufacturing process.

The Nasality Microphone is handheld rather than head-mounted, which many users find more comfortable and practical, particularly when working with children. Disposable foam windshields protect the microphone elements and prevent cross contamination between speakers. Its portable design makes it well suited to home visits, fieldwork, and university programmes where budget and portability matter.

The Nasality Microphone has been used as a validated comparator in peer-reviewed research.

The acoustic separator is positioned above the upper lip and does not enter the mouth or nasal passage. Disposable foam windshields are available as replacement accessories and are recommended for use between different speakers to protect the microphone elements. The acoustic separator and housing can be wiped with standard surface disinfectants. Please contact us for specific hygiene guidance relevant to your setting.

Normative nasalance scores vary by language, speaker age, and the passage stimuli used during measurement. Published research using the Nasality Microphone provides population-specific normative values. For example, Peris-Hernández, Rosell-Clari and Kummer (2024) established normative nasalance values for Spanish-speaking children aged 3 to 5 years using the Nasality Microphone, reporting high internal consistency across vowels, syllables, and phrases.

Yes. The Nasality Microphone has been used in peer-reviewed research published in international journals, including studies measuring nasalance in cleft palate and hypernasal populations, and studies in which the Nasality Microphone was used as a comparator instrument when validating novel nasometry systems. When citing the device in publications, please reference it as: Nasality Microphone, icSpeech, a division of Rose Medical Solutions Ltd., Canterbury, UK. A list of publications featuring icSpeech technology is available on the publications page.

The Nasality Microphone uses a fixed band pass filter with a centre frequency of 500Hz and a frequency range of 350–650Hz to isolate the frequency range that best reflects nasal resonance and to minimise interference from irrelevant acoustic information. Using a fixed band pass filter ensures that nasalance scores remain consistent across different sessions, subjects, and nasometry devices. The nasal and oral microphones are also individually matched during manufacturing for both sensitivity and frequency response, further ensuring measurement accuracy.

NasalanceViewer, NasalanceViewer 3D, and icSpeech Professional Edition currently support Windows 10 and Windows 11 only. The Nasality Microphone hardware uses standard USB audio and is not platform-restricted, but the software requires Windows. Users working in Mac environments may wish to run Windows via Boot Camp or a virtual machine. Please contact us to discuss your setup — we are happy to advise on the best approach for your environment.

The Nasality Microphone connects to a local Windows computer and captures nasalance data locally. A speech professional or trained assistant can operate the device with the speaker present, while a remote supervisor observes via video call. Nasalance data and recordings can be exported and shared with a remote colleague for review. Direct real-time streaming of nasalance data over a video connection is not a standard configuration. Contact us to discuss remote working workflows.
