Portable nasometry unit
The Nasality Microphone is a handheld nasometry unit that detects nasality in speech production. It uses a lightweight acoustic separator that is fitted with highly directional nasal and oral microphones. The portable design and USB compatibility makes the Nasality Microphone ideal for clinical or home-based speech therapy.
How nasometry works
The Nasality Microphone uses a special lightweight acoustic separator that is positioned above the upper lip. The acoustic separator is fitted with independent nasal and oral microphones.
Nasality is represented by a numerical value called nasalance, which is defined as the percentage of the total acoustic energy that is nasal:
Nasalance can be monitored in real-time for biofeedback therapy, or recorded for off-line assessment.
The Nasality Microphone comes complete with NasalanceViewer, an easy-to-use Windows application that supports the following features:
icSpeech Professional Edition
The Nasality Microphone is also compatible with icSpeech Professional Edition (sold separately), which supports a wealth of additional features, including:
The real-time Bar is a useful biofeedback tool that shows a simple bar, which moves upwards with increased nasalance. This allows the user to monitor nasality, make corrections, and instantly see the result.
The real-time Waveform display is often used in therapy because it allows the user to see the dynamics of their speech during the utterance of complete words or phrases.
Each of the six interactive games feature adjustable targets, rewards and can be controlled with nasalance, pitch, nasal or oral acoustic energy.
