Use of low power EM radar sensors for speech articulator measurements
نویسندگان
چکیده
Very low power electromagnetic (EM) wave sensors are being used to measure speech articulator motions such as the vocal fold oscillations, jaw, tongue, and the soft palate. Data on vocal fold motions, that correlate well with established laboratory techniques, as well as data on the jaw, tongue and soft palate are shown The vocal fold measurements together with a volume air flow model are being used to perform pitch synchronous estimates of the voiced transfer functions using ARMA techniques.

Direct and Indirect Measures of Speech Articulator Motions Using Low Power EM Sensors
Low power Electromagnetic (EM) Wave sensors can measure general properties of human speech articulator motions, as speech is produced. See Holzrichter, Burnett, Ng, and Lea, J.Acoust.Soc.Am. 103 (1) 622 (1998). Experiments have demonstrated extremely accurate pitch measurements (< 1 Hz per pitch cycle) and accurate onset of voiced speech. Recent measurements of pressure-induced tracheal motions...
متن کاملMicropower electro-magnetic sensors for speech characterization, recognition, verification, and other applications
Experiments have been conducted using a variety of very low power EM sensors that measure articulator motions occurring in two frequency bands, 1 Hz to 20Hz, and 70 Hz to 7 kHz. They enable noise free estimates of a voiced excitation function, accurate pitch measurements, generalized transfer function descriptions, and detection of vocal articulator motions.
متن کاملCharacterizing silent and pseudo-silent speech using radar-like sensors
Radar-like sensors enable the measuring of speech articulator conditions, especially their shape changes and contact events both during silent and normal speech. Such information can be used to associate articulator conditions with digital “codes” for use in communications, machine control, speech masking or canceling, and other applications.
متن کاملLow Bandwidth Vocoding Using Em Sensor and Acoustic Signal Processing
Low-power EM radar-like sensors have made it possible to measure properties of the human speech production system in real-time, without acoustic interference [1]. By combining these data with the corresponding acoustic signal, we’ve demonstrated an almost 10-fold bandwidth reduction in speech compression, compared to a standard 2.4 kbps LPC10 protocol used in the STU-III (Secure Terminal Unit, ...
متن کاملEfficiency of Target Location Scenarios in the Multi-Transmitter Multi-Receiver Passive Radar
Multi-transmitter multi-receiver passive radar, which locates target in the surveillance area by the reflected signals of the available opportunistic transmitter from the target, is of interest in many applications. In this paper, we investigate different signal processing scenarios in multi-transmitter multi-receiver passive radar. These scenarios include decentralized processing of reference ...
