VoiScan: Telephone Voice Analysis for Health and Biometric Applications

摘要

The telephone, whether mobile, landline, or VoIP, is probably the most widely used form of long-distance communication. The most common use of voice biometrics is in telephone-based speaker verification, so the ability to operate effectively over the telephone is crucial. Similarly, access to vocal health monitoring, and other voice analysis technology, would benefit enormously if it were available over the telephone, via an automatic system. This paper describes a set of voice analysis algorithms, designed to be robust against the kinds of distortion and signal degradation encountered in modern telephone communication. The basis of the algorithms in traditional analysis is discussed, as are the design choices made in order to ensure robustness. The utility of these algorithms is demonstrated in a number of target domains.
