If { d 1, d 2, …, d K - 1, d K } are the frame indices that mark the boundaries of the segments, then a sequence of K segments can be represented as a sequence of pairs: { ( 1, d 1), ( d 1 + 1, d 2), ⋯, ( d K - 1 + 1, L) }, where T dmin ≤ d 1 < d 2 … < d K = L and T dmax ≥ d k - d k - 1 ≥ T dmin, k = 2, …, K.

segmentation and classification of audio into three classes. Figure 1. 1 Segmentation and classification of audio data. 1.1 Project Objective The main goal of this project was, initially to design a system that would be able to classify audio signals into music or speech. The classification task was further to be extended to

Segmentation Guideline
https://samplesegmentation.theaudiobee.com/public/guidelines.html
Segmentation If overlapping speech is occurring: the segment boundaries should be accurate with at least 100milliseconds precision, if possible. If overlapping speech is NOT occurring, the segment boundaries do not have to be 100% precise but should start and end within 85-100milliseconds from when the speaker begins/ends their speech.
