Abstract
This speech processing device is provided with: a contribution degree estimation means which calculates a contribution degree representing a quality of a segment of the speech signal; and a speaker feature calculation means which calculates a feature from the speech signal, for recognizing attribute information of the speech signal, using the contribution degree as a weight of the segment of the speech signal.
Claims13
A speech processing device, comprising:
- a processor;
- and
- memory storing executable instructions that, when executed by the processor, causes the processor to perform as:
- a contribution degree estimation unit configured to calculate a contribution degree representing a quality of a segment of a speech signal indicative of speech, the speech signal being divided into a plurality of segments;
- and
- a speaker feature calculation unit configured to calculate a speaker feature from the speech signal, for recognizing attribute information of the speech signal, using the contribution degree as a weight of each segment of the speech signal, the speaker feature being indicative of individuality for identifying a speaker which utters the speech.
A speech processing method comprising:
- calculating a contribution degree representing a quality of a segment of a speech signal indicative of speech, the speech signal being divided into a plurality of segments;
- and
- calculating a speaker feature from the speech signal, for recognizing attribute information of the speech signal, using the contribution degree as a weight of each segment of the speech signal, the speaker feature being indicative of individuality for identifying a speaker which utters the speech.
A non-transitory computer readable recording medium for storing a speech processing program for causing a computer to execute:
- a process for calculating a contribution degree representing a quality of a segment of a speech signal indicative of speech, the speech signal being divided into a plurality of segments;
- and
- a process for calculating a speaker feature from the speech signal, for recognizing attribute information of the speech signal, using the contribution degree as a weight of each segment of the speech signal, the speaker feature being indicative of individuality for identifying a speaker which utters the speech.
