[0027] figure 2 is a functional block diagram showing the speech processing device 1 according to the embodiment. The speech processing device 1 includes a receiving unit 2 , a detecting unit 3 , a computing unit 4 , a control unit 5 and an output unit 6 .

[0028] The receiving unit 2 is realized, for example, by a wired logic hardware circuit. Alternatively, the receiving unit 2 may be a functional module realized by a computer program executed in the speech processing device 1 . The receiving unit 2 externally acquires a near-end signal transmitted from the receiving side (the user of the voice processing device 1 ) and a first far-end including an uttered voice transmitted from the transmitting side (the person communicating with the user of the voice processing device 1 ). Signal. The receiving unit 2 may receive, for example, a near-end signal from a microphone (not shown) connected to or arranged in the speech processing device 1 . The receiving unit 2 may receive ...

[0061] exist image 3 Among them, the determination unit 7 can change the control amount (non_sp) by the adjustment amount (r_delta) according to the signal characteristic of the first remote signal. The signal characteristic of the first remote signal may be, for example, a signal-to-noise ratio (SNR) or a noise characteristic value of the first remote signal. For example, the noise feature value may be calculated in a manner similar to the way in which the calculation unit 4 calculates the noise feature value of the near-end signal. For example, the processing unit 9 may calculate the noise characteristic value of the first far-end signal, and the determination unit 7 may receive the calculated noise characteristic value from the processing unit 9 . A signal-to-noise ratio (SNR) may be calculated by the processing unit 9 using a signal-to-noise characteristic value ratio in the speech segment of the first far-end signal, and the determination unit 7 may receive the signal-t...

[0065] exist image 3 Among them, in addition to control information #1 (ctrl-1), the generating unit 8 may generate control information #2 (ctrl-2) for controlling the speech segment length based on the speech segment length and delay. The processing performed by the generating unit 8 to generate control information #2 (ctrl-2) is described below. For the non-speech segment length, the generation unit 8 generates control information #2 (ctrl-2) such that ctrl-2=0, for example.

[0066] Please note that when ctrl-2=0, no control processing including expansion or reduction is performed on the voice segment of the first remote signal. Regarding the length of the speech segment, the generation unit 8 generates control information #2 (ctrl-2) such as ctrl-2=er, where er represents the expansion ratio of the speech segment. Note that the generation unit 8 may generate control information #2 (ctrl-2) such that ctrl-2=0 according to the delay even for the speech segment length. Th...

Abstract

A voice processing device includes, a receiving unit configured to receive a first signal including a plurality of voice segments; a control unit configured to control such that a non-voice segment with a length equal to or greater than a predetermined first threshold value exists between at least one of the plurality of voice segments; and an output unit configured to output a second signal including the plurality of voice segments and the controlled non-voice segment.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2012-270916 filed on December 12, 2012, the entire contents of which are hereby incorporated by reference. technical field [0003] The embodiments discussed herein relate to, for example, a voice processing device configured to control an input signal, a voice processing method, and a voice processing program. Background technique [0004] One known method is to control a speech signal given as an input signal so that the speech signal is easy to hear. For example, in the elderly, speech recognition ability may decrease due to hearing loss with aging. Therefore, when a speaker speaks at a high speech rate in two-way voice communication using a portable communication terminal or the like, it tends to become difficult for elderly people to hear the voice. One of the simplest ways to deal with the above situation is for the spea...
