Abstract
A system and method for detecting a refrain in an audio file having vocal components. The method and system includes generating a phonetic transcription of a portion of the audio file, analyzing the phonetic transcription and identifying a vocal segment in the generated phonetic transcription that is repeated frequently. The method and system further relate to the speech-driven selection based on similarity of detected refrain and user input.
Claims13
A method for detecting a refrain in an audio file having vocal components, the method comprising:
- generating a phonetic transcription of at least a portion of the audio file;
- analyzing the phonetic transcription to detect vocal segments in the generated transcription;
- determining if the detected vocal segment is repeated in the generated phonetic transcription at least once;
- and
- identifying at least one repeated vocal segment in the generated phonetic transcription to be the refrain.
A method for processing an audio file having at least vocal components, the method comprising:
- detecting a refrain of the audio file by identifying repeated vocal segments in a phonetic transcription of at least a portion of the audio file;
- generating either or both a phonetic or acoustic representation of the refrain;
- and
- storing the generated phonetic or acoustic representation together with the audio file in memory.
A system for detecting a refrain in an audio file having at least vocal components, the system comprising:
- a phonetic transcription unit that generates a phonetic transcription of at least a portion of the audio file;
- an analyzing unit that analyzes the generated transcription to detect vocal segments, determines if any detected vocal segment is repeated at least once in the generated transcription, and identifies at least one of the repeated vocal, segments to be the refrain.
A system for processing an audio file having at least vocal components, the system comprising:
- a transcription unit that generates a phonetic representation of the audio file;
- a detecting unit that detects the refrain of the audio file by identifying repeated vocal segments in the phonetic representation of at least a portion of the audio file;
- a control unit that stores the phonetic representation linked to the audio data in memory.
