Abstract
Official abstract text for this publication.
A band broadening apparatus includes a processor configured to analyze a fundamental frequency based on an input signal bandlimited to a first band, generate a signal that includes a second band different from the first band based on the input signal, control a frequency response of the second band based on the fundamental frequency, reflect the frequency response of the second band on the signal that includes the second band and generate a frequency-response-adjusted signal that includes the second band, and synthesize the input signal and the frequency-response-adjusted signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A band broadening apparatus comprising a processor in communication with a memory, wherein the memory contains programmed instructions which when executed by the processor perform the following steps: analyze a fundamental frequency based on an input speech signal bandlimited to a first band, generate a second speech signal that includes a second band different from and bandbroadened from the first band based on the input speech signal, control a frequency…
