Audio processing techniques for semantic audio recognition and report generation

An apparatus comprising:

• at least one memory;
• computer readable instructions in the apparatus;
• and
• at least one processor to execute the computer readable instructions to at least:
• process a first frame of an audio signal to determine first values of a plurality of features of the audio signal;
• associate the first frame of the audio signal with at least one of first semantic information or second semantic information based on comparison of the first values of the plurality of features to a first template associated with the first semantic information and comparison of the first values of the plurality of features to a second template associated with the second semantic information, the first template having corresponding first ranges of the plurality of features, the second template having corresponding second ranges of the plurality of features;
• process a second frame of the audio signal to determine second values of the plurality of features;
• and
• associate the second frame of the audio signal with at least one of the first semantic information or the second semantic information based on comparison of the second values of the plurality of features to the first template associated with the first semantic information and comparison of the second values of the plurality of features to the second template associated with the second semantic information.

At least one article of manufacture comprising computer readable instructions which, when executed, cause at least one processor to at least:

• process a first frame of an audio signal to determine first values of a plurality of features of the audio signal;
• associate the first frame of the audio signal with at least one of first descriptive information or second descriptive information based on comparison of the first values of the plurality of features to a first template associated with the first descriptive information and comparison of the first values of the plurality of features to a second template associated with the second descriptive information, the first template having corresponding first ranges of the plurality of features, the second template having corresponding second ranges of the plurality of features;
• process a second frame of the audio signal to determine second values of the plurality of features;
• and
• associate the second frame of the audio signal with at least one of the first descriptive information or the second descriptive information based on comparison of the second values of the plurality of features to the first template associated with the first descriptive information and comparison of the second values of the plurality of features to the second template associated with the second descriptive information.

A method comprising:

• processing a first frame of an audio signal to determine first values of a plurality of features of the audio signal;
• associating, by executing an instruction with at least one processor, the first frame of the audio signal with at least one of first descriptive information or second descriptive information based on comparison of the first values of the plurality of features to a first template associated with the first descriptive information and comparison of the first values of the plurality of features to a second template associated with the second descriptive information, the first template having corresponding first ranges of the plurality of features, the second template having corresponding second ranges of the plurality of features;
• processing a second frame of the audio signal to determine second values of the plurality of features;
• and
• associating, by executing an instruction with the at least one processor, the second frame of the audio signal with at least one of the first descriptive information or the second descriptive information based on comparison of the second values of the plurality of features to the first template associated with the first descriptive information and comparison of the second values of the plurality of features to the second template associated with the second descriptive information.
