To provide translation techniques for translating a natural language representation in one language into a natural language representation in another language using sound. With Land Lbeing different languages from each other, a translation data generation apparatus includes: a latent variable generation unit that generates, from a natural language representation in the language L, a latent variable corresponding to the natural language representation in the language Lusing a language Lencoder; an index calculation unit that calculates an index for the natural language representation in the language Lfrom the natural language representation in the language L; and a natural language representation generation unit that generates a natural language representation in the language Lcorresponding to the natural language representation in the language Lfrom the latent variable and the index for the natural language representation in the language Lusing a language Ldecoder.

To provide techniques for generating, from a sound signal, a natural language representation corresponding to the sound signal while controlling a predetermined index for a natural language representation. A data generation apparatusincludes: a latent variable generation unitthat generates, from a sound signal, a latent variable corresponding to the sound signal using an encoder; and a data generation unitthat generates a natural language representation corresponding to the sound signal from the latent variable and a condition concerning an index for the natural language representation using a decoder.

To provide database generation techniques that can accurately and efficiently generate a database useable in text-based sound signal search. A sound signal database generation apparatus includes: a latent variable generation unit that generates, from a sound signal, a latent variable corresponding to the sound signal using a sound signal encoder; a data generation unit that generates a natural language representation corresponding to the sound signal from the latent variable and a condition concerning an index for a natural language representation using a natural language representation decoder; and a sound signal database generation unit that generates a record including the natural language representation corresponding to the sound signal and the sound signal from the natural language representation corresponding to the sound signal and the sound signal, and generates a sound signal database made up of the record.
