Abstract
A method for generating voice dictionary is disclosed which makes it possible to improve the accuracy of speaker identification. A method according to an aspect of the present disclosure includes: acquiring voices of a plurality of unspecified speakers; acquiring noise in a predetermined place; superimposing the noise onto the voices of the plurality of unspecified speakers; and generating, on the basis of the features of the voices of the plurality of unspecified speakers, unspecified speaker voice dictionary that is used for generating personal voice dictionary for identifying a target speaker.
Claims8
A method comprising:
- acquiring, via a processor, voices of a plurality of unspecified speakers;
- acquiring, via the processor, noise in a predetermined place;
- adjusting, via the processor, a sound pressure of the noise based on sound pressures of the voices of the plurality of unspecified speakers;
- superimposing, via the processor, the noise whose sound pressure has been adjusted onto the voices of the plurality of unspecified speakers;
- and
- generating, via the processor, an unspecified speaker voice dictionary from features of the voices of the plurality of unspecified speakers onto which the noise has been superimposed,
- wherein the unspecified speaker voice dictionary is used in generating a personal voice dictionary for identifying a target speaker.
An apparatus comprising:
- a processor;
- and
- a memory storing therein a computer program, which when executed by the processor, causes the processor to perform operations including:
- acquiring voices of a plurality of unspecified speakers;
- acquiring noise in a predetermined place;
- adjusting a sound pressure of the noise based on sound pressures of the voices of the plurality of unspecified speakers;
- superimposing the noise whose sound pressure has been adjusted onto the voices of the plurality of unspecified speakers;
- and
- generating an unspecified speaker voice dictionary from features of the voices of the plurality of unspecified speakers onto which the noise has been superimposed,
- wherein the unspecified speaker voice dictionary is used in generating personal voice dictionary for identifying a target speaker.
A non-transitory recording medium storing thereon a computer program, which when executed by a processor, causes the processor to perform operations comprising:
- acquiring voices of a plurality of unspecified speakers;
- acquiring noise in a predetermined place;
- adjusting a sound pressure of the noise based on sound pressures of the voices of the plurality of unspecified speakers;
- superimposing the noise whose sound pressure has been adjusted onto the voices of the plurality of unspecified speakers;
- and
- generating an unspecified speaker voice dictionary from features of the voices of the plurality of unspecified speakers onto which the noise has been superimposed,
- wherein the unspecified speaker voice dictionary is used in generating personal voice dictionary for identifying a target speaker.
