Embodiment Construction

[0021] A speech processing device, a speech processing method, and a computer program according to an embodiment will now be explained in detail with reference to the accompanying drawings. The speech processing apparatus according to this embodiment extracts the harmonic components of human speech in input sound prior to speech detection or fundamental frequency estimation. The input sound is a signal including sound and is input to the speech processing device according to this embodiment. In this embodiment, a signal including speech segments which are segments corresponding to human speech and non-speech segments is input as input sound to the speech processing device.

[0022] First, we will now refer to figure 1 The configuration of the speech processing apparatus according to this embodiment will be explained. figure 1 is a block diagram showing an exemplary functional configuration of the speech processing apparatus 1 according to this embodiment. like figure 1 As ...

Abstract

The invention discloses a speech processing apparatus and a speech processing method. According to an embodiment, the speech processing apparatus includes an enhancer, a converter, a filter, and an inverter. The enhancer is configured to generate a frequency spectrum in which a harmonic component included in input sound is enhanced. The converter is configured to convert the frequency spectrum into a first signal in a modulation frequency domain. The filter is configured to filter the first signal to pass human speech. The inverter is configured to convert the filtered first signal into a second signal in a frequency domain.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Japanese Patent Application No. 2015-010666 filed on January 22, 2015; the entirety of which is incorporated herein by reference. technical field [0003] Embodiments described herein relate generally to speech processing devices and speech processing methods. Background technique [0004] The harmonic structure observed in the vowel portion of a speech signal to which frequency conversion has been applied is important information for detecting speech segments and estimating the fundamental frequency. In order to find out the harmonic structure, various methods for extracting harmonic components, which are frequency components constituting the harmonic structure, from speech signals have been disclosed. [0005] All such conventionally disclosed harmonic component extraction methods extract frequency components having stronger power than those of adjacent frequency...
