- detecting a refrain in each of the audio files of the plurality of audio files;
- determining either or both phonetic or acoustic representations of at least part of a refrain of each of the audio files;
- supplying each of the phonetic or acoustic representations to a speech recognition unit;
- comparing the phonetic or acoustic representations to the voice command of the user of the audio player;
- and
- selecting an audio file based on the best matching result of the comparison.
A system for a speech-driven selection of an audio file comprising:
- a refrain detecting unit that detects the refrain of an audio file;
- a transcription unit that generates a phonetic or acoustic representation of the detected refrain;
- a speech recognition unit that compares the phonetic or acoustic representation to the voice command of the user selecting the audio file and that determines the best matching result of the comparison;
- and
- a control unit that selects the audio file in accordance with the result of the comparison.
