Abstract

We present an analysis of clustering audio clips using word descriptions that are imitative of sounds. These onomatopoeia words describe the acoustic properties of sources, and they can be useful in annotating a medium that cannot embed audio (e.g. text). First, an audio-to-word relationship is established by manually tagging a variety of audio clips (from a sound effects library) with onomatopoeia words. Using a newly proposed distance metric for word-level similarities, the feature vectors from the audio are clustered according to their tags, resulting in clusters with similarities in their onomatopoeic descriptions. By discriminant analysis of the clusters at the feature level, we present results on separability of these clusters. Our results indicate that by just using onomatopoeic descriptions, meaningful clusters with similar acoustic properties can be formed. However, in terms of audio feature level representation …
