Device for Enhancing Electrolaryngeal Speech

We will develop a system for enhancing the intelligibility and naturalness of electrolaryngeal (EL)device would employ digital filtering techniques to compensate for known deficits in the low-frequenof hue source function of typical electronic larynxes such as the Servox device. It would also removmid- and high-frequency masking noise resulting from the direct acoustic radiation of the electronicwould be implemented as software running on a commercial personal computer outfitted with a commerciincluding an internal DSP coprocessor and the capability to interface with the telephone. The systemlarynectomees to enhance the clarity of their speech when using the telephone, addressing public gatsituation where an electronic audio system could reasonably be employed. Phase I has two goals. Thewhether a specific set of proposed filtering techniques can enhance the intelligibility and naturalnsecond is to determine whether these techniques can be implemented in a usable fashion on commercialto produce a practical product.National Institute of Dental Research (NIDR)
