Vocal tract area based artificial bandwidth extension

In this paper we present a method of artificial bandwidth extension based on vocal tract areas. This method exploits the many-to-one mapping between the vocal tract areas and linear prediction polynomial, and the quasi-stationary nature of speech to estimate the high-frequency (4 kHz to 8 kHz) compo...
