Sound generation apparatus
View Patent ↗A sound generation apparatus includes sound collection means configured to collect a sound of a sound source in a space, image capture means configured to capture an image of the sound source, estimation means configured to estimate an attribute of the sound source from the image captured by the image capture means, sound generation means configured to obtain an acoustic characteristic of a target sound included in the sound collected by the sound collection means and to generate multiple masking sounds on the basis of the acoustic characteristic and the attribute of the sound source estimated by the estimation means, display means configured to display the attribute of the sound source estimated by the estimation means, sound selection means configured to receive selection of a masking sound from the masking sounds generated by the sound generation means, and sound output means configured to output the selected masking sound.
1. A sound generation apparatus comprising:
sound collection means configured to collect a sound of a sound source in a space;
image capture means configured to capture an image of the sound source;
estimation means configured to estimate an attribute of the sound source from the image captured by the image capture means;
sound generation means configured to obtain an acoustic characteristic of a target sound included in the sound collected by the sound collection means and to generate a plurality of masking sounds on the basis of the acoustic characteristic and the attribute of the sound source estimated by the estimation means;
display means configured to display the attribute of the sound source estimated by the estimation means;
sound selection means configured to receive a selection of a masking sound from the masking sounds generated by the sound generation means; and
sound output means configured to output the selected masking sound.
2. The sound generation apparatus of claim 1 , wherein the sound generation means analyzes an acoustic characteristic of the sound of the sound source collected by the sound collection means and generates a masking sound having an acoustic characteristic similar to the acoustic characteristic of the sound of the sound source.
3. The sound generation apparatus of claim 1 , wherein the sound generation means generates a masking sound having an acoustic characteristic similar to an acoustic characteristic of the attribute of the sound source estimated by the estimation means.
4. The sound generation apparatus of claim 3 , wherein the sound generation means generates a plurality of masking sounds each having an acoustic characteristic similar to the acoustic characteristic of the attribute of the sound source.
5. The sound generation apparatus of claim 1 , wherein the sound selection means displays the attribute of the sound source estimated by the estimation means and receives the selection of the masking sound.
6. The sound generation apparatus of claim 5 , wherein the display means displays the sound source using mixed reality including virtual reality, augmented reality, or a hologram.
7. The sound generation apparatus of claim 1 , wherein the sound collection means is an omnidirectional microphone.
8. The sound generation apparatus of claim 1 , wherein the sound of the sound source in the space is a voice of a conversation of a user using the sound generation apparatus.
9. The sound generation apparatus of claim 8 , wherein the sound output means outputs the masking sound as long as the sound collection means is collecting the sound of the sound source.
10. The sound generation apparatus of claim 2 , wherein the sound of the sound source in the space is a voice of a conversation of a user using the sound generation apparatus.
11. The sound generation apparatus of claim 10 , wherein the sound output means outputs the masking sound as long as the sound collection means is collecting the sound of the sound source.
