See [14] for more details about collecting onomatopoeic words. The audio clips are originally recorded
with 44.1kHz (stereo) sampling rate. Table 1 shows examples from the BBC sound library along with various labels: semantic labels, onomatopoeic words, and short text descriptions. Both examples include the sound of a goat; while the subjective annotation of onomatopoeic words are the same, the semantic categories are different. These examples show the ambiguity of information even when they include the same audio contents. A summary of the database is given
in Table 2.
