Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: A non-audible murmur (NAM), a very ak whisper sound produced without vocal fold vibration, has been researched in the development of a silent-speech communication tool for functional speech disorders as ll as human-to-human/machine interfaces with inaudible voice input. The NAM can be detected using a specially designed microphone, called a NAM microphone, attached to the neck. Hover, the detected NAM signal has a low signal-to-noise ratio and severely suppressed high-frequency component. To improve NAM clarity, the mechanism of a NAM production must be clarified. In this work, an air flow through a glottis in the vocal tract was numerically simulated using computational fluid dynamics and vocal tract shape models that are obtained by a magnetic resonance imaging (MRI) scan for whispered voice production with various strengths, i.e. strong, ak, and very ak. For a very ak whispering during the MRI scan, subjects re trained, just before the scanning, to produce the very ak whispered voice, or the NAM. The numerical results show that a ak vorticity flow occurs in the supraglottal region even during a very ak whisper production; such vorticity flow provide aeroacoustic sources for a very ak whispering, i.e. NAM, as in an ordinary whispering.
