Speech Visualisation Technology
Speech is the result of a highly complex system of co-ordinated muscular movements. While perceptual assessment provides valuable information, instrumental observation and measurement offer significant advantages. Explore our range of speech visualisation instrumentation and software, designed for researchers, clinicians and educators.
Nasometry
Nasality Microphone
Measures nasalance during speech production using a lightweight, portable, USB-powered acoustic separator fitted with highly directional nasal and oral microphones.
Electropalatography (EPG)
LinguaGraph
Detects tongue contact with the hard palate during speech using a custom-made artificial palate containing 62 electrodes embedded on its lingual surface.
Ultrasound Tongue Imaging (UTI)
LinguaSound 3D
Enhanced ultrasound tongue imaging software featuring automated contour estimation and 3D modelling for real-time visualisation of the tongue and hard palate.
Anemometry
Super Nasal-Oral Ratiometry System (SNORS)
Detects nasal and oral airflow during speech using a lightweight dual chamber mask, providing objective measurement of velopharyngeal function.
Electroglottography (EGG)
EGG-D200
A non-invasive technique for monitoring vocal fold vibration by sensing the electrical conductance between two electrodes placed either side of the thyroid cartilage.
Multiparameter speech software
icSpeech Professional Edition
Flexible USB architecture enables synchronous data capture from any combination of icSpeech speech instrumentation for multiparameter analysis.

Voice in Space
In 2025, icSpeech supplied instrumentation for use aboard the International Space Station as part of Axiom Mission 4. The Voice in Space experiment investigates how the human voice changes in a zero-gravity environment, using electroglottography to provide objective data on vocal fold function during spaceflight.
