Abstract
Disclosed is an information display system provided with: a signal analyzing unit which analyzes the audio signals obtained from a predetermined location and which generates ambient sound information regarding the sound generated at the predetermined location; and an ambient expression selection unit which selects an ambient expression which expresses the content of what a person is feeling from the sound generated at the predetermined location on the basis of the ambient sound information.
Claims15
An atmosphere expression word selection system, comprising:
- a signal analyzing unit that analyzes audio signals and prepares atmospheric sound information related to a sound that is being generated in an acquisition location of said audio signals;
- and
- an atmosphere expression word selecting unit that selects an atmosphere expression word expressing what a person feels from the sound that is being generated in said acquisition location based on said atmospheric sound information,
- wherein said signal analyzing unit analyzes at least one of a sound pressure level of the audio signals, frequency information representing features of a frequency of the audio signals, and a classification of the sound of the audio signals, and prepares the atmospheric sound information, and
- wherein in a case in which said atmospheric sound information includes the sound pressure level, said atmosphere expression word selecting unit selects the atmosphere expression word expressing a louder noise as said sound pressure level becomes larger.
An atmosphere expression word selection method, comprising:
- analyzing audio signals, and preparing atmospheric sound information related to a sound that is being generated in an acquisition location of said audio signals;
- and
- analyzing at least one of a sound pressure level of the audio signals, frequency information representing features of a frequency of the audio signals, and a classification of the sound of the audio signals;
- and
- selecting an atmosphere expression word expressing what a person feels from the sound that is being generated in said acquisition location based on the analyzing at least one of a sound pressure level of the audio signals, frequency information representing features of a frequency of the audio signals, and a classification of the sound of the audio signals, wherein in a case in which said atmospheric sound information includes the sound pressure level, the atmosphere expression word expressing a louder noise as said sound pressure level becomes higher.
A non-transitory computer readable storage medium storing a program for causing an information processing apparatus to execute:
- analyzing audio signals and preparing atmospheric sound information related to a sound that is being generated in an acquisition location of said audio signals;
- and
- analyzing at least one of a sound pressure level of the audio signals, frequency information representing features of a frequency of the audio signals, and a classification of the sound of the audio signal;
- selecting an atmosphere expression word representing what a person feels from the sound that is being generated in said acquisition location based on said analyzing at least one of a sound pressure level of the audio signals, frequency information representing features of a frequency of the audio signals, and a classification of the sound of the audio signals, wherein in a case in which said atmospheric sound information includes the sound pressure level, the atmosphere expression word expressing a louder noise as said sound pressure level becomes higher.
