Abstract
For example, an effective voice quality conversion process is performed. An information processing apparatus includes: a voice quality conversion unit that performs sound source separation of a vocal signal and an accompaniment signal from a mixed sound signal and performs voice quality conversion using a result of the sound source separation.
Claims18
An information processing apparatus comprising:
- circuitry including an encoder and a decoder and configured to
- perform sound source separation of a vocal signal and an accompaniment signal from a mixed sound signal,
- perform voice quality conversion using a result of the sound source separation, the sound separation including separation of a first vocal signal from the mixed sound signal,
- bring one vocal signal of the first vocal signal and a second vocal signal closer to another vocal signal, and
- estimate a feature amount related to an utterer, wherein
- the feature amount related to the utterer corresponds to a feature that does not change with time,
- the encoder is configured to extract, from an input vocal signal, a feature amount corresponding to a feature that changes with time, and
- the decoder is configured to generate a vocal signal based on the estimated feature amount and the feature amount extracted by the encoder.
An information processing method comprising:
- performing, using a processor configured to implement an encoder and a decoder, sound source separation of a vocal signal and an accompaniment signal from a mixed sound signal;
- performing, using the processor, voice quality conversion using a result of the sound source separation;
- bringing, using the processor, one vocal signal of the first vocal signal and a second vocal signal closer to another vocal signal;
- estimating, using the processor, a feature amount related to an utterer;
- extracting from an input vocal signal, using the encoder, a feature amount corresponding to a feature that changes with time;
- and
- generating a vocal signal based on the estimated feature amount and the feature amount extracted using the decoder, wherein
- the feature amount related to the utterer corresponds to a feature that does not change with time.
A non-transitory computer-readable storage medium having stored thereon instructions that, when executed by one or more processors, causes the one or more processors to perform a method implementing an encoder and a decoder, the method comprising:
- performing, sound source separation of a vocal signal and an accompaniment signal from a mixed sound signal;
- performing voice quality conversion using a result of the sound source separation;
- bringing one vocal signal of the first vocal signal and a second vocal signal closer to another vocal signal;
- estimating a feature amount related to an utterer;
- extracting from an input vocal signal, using the encoder, a feature amount corresponding to a feature that changes with time;
- generating a vocal signal based on the estimated feature amount and the feature amount extracted using the decoder, wherein
- the feature amount related to the utterer corresponds to a feature that does not change with time.
