Audio Segmentation - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/engineering/audio-segmentation
Keywords may be used to reduce indexing and provide abstraction for video sequences. There are many possibilities for language processing in video, but the audio track must first exist as an ASCII document or speech recognition is necessary. Audio segmentation is needed to distinguish spoken words from music, noise, and silence. Further analysis through speech recognition is …
Innovative Technique for Audio Segmentation

Vowel regions initiate when the vowel onset point occurs and ends when vowel offset point occurs. Audio segmentation is also possible, by dividing an audio stream into segments, on the basis of vowel regions . Audio segmentation algorithms can be divided into three general categories. In the first category, classifiers are designed . The features are extracted in time …
Audio Segmentation and Classification
http://www2.imm.dtu.dk/pubdb/edoc/imm3851.pdf
Lie Lu et el in their work on audio classification and segmentation have used features such as high zero crossing rate, low short time energy ratio (LSTER) and spectrum flux (SF). Hugo Meindo and J. Neto [3] in their work on audio segmentation, classification, and clustering have used symmetric Kullback-Liebler, KL2, for audio segmentation.

segmentation algorithms that are computationally ef ¿ cient. Current approaches for audio segmentation include both super-vised and unsupervised techniques. Supervised segmentation meth-ods can be categorized as model-based or decoder-based. In model-based segmentation [1], Gaussian mixture models are constructed fora ¿ xedsetofacousticclasses.

In our proposed work, mean filtering is utilized for filtering the audio signal. Better reduction in the Gaussian noise is achieved than the traditional filtering techniques. Segmentation of the audio signal is performed using the peak estimation and pitch extraction. Then, the spectral difference in the audio signal pattern is estimated.

Proposed Approach. ‣Idea:Make use of music segmentation techniques to obtain the most repeated parts of a given audio track: ‣ Segment boundaries sometimes characterized by the amount of. repetition. ‣ Music segmentation task typically works on audio (instead of score). Proposed Approach - Pipeline.

2. MUSIC SEGMENTATION TECHNIQUES The task of music segmentation is well-established in the music informatics literature (see [18] for a review). Its goal is to automatically identify all the non-overlapping musi-cal segments (or sections) of a given track, such that the concatenation of all of them reconstructs the entire piece.
