(PDF) A Large Margin Algorithm for Speech-to-Phoneme …

    1 A Large Margin Algorithm for Speech-to-Phoneme and Music-to-Score Alignment Joseph Keshet, Shai Shalev-Shwartz, Yoram Singer, Dan Chazan Abstract— We describe and analyze a discriminative algorithm and overfitting effects due to the large number of parame- for learning to align an audio signal with a given sequence ters.

Optimized Audio Classification and 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 - an overview | ScienceDirect Topics

    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.

GitHub - lumaku/ctc-segmentation: Segment an audio file ...

    CTC segmentation can be used to find utterance alignments within large audio files. This repository contains the ctc-segmentation python package. A description of the algorithm is in the CTC segmentation paper (on Springer Link, on ArXiv) Usage. The CTC segmentation package is not standalone, as it needs a neural network with CTC output.

Evaluation of BIC-based algorithms for audio …

    The 2000 NIST Speaker Recognition Evaluation included a segmentation task, where systems were required to identify speech segments corresponding to each of two unknown speakers.The test set consists of 1000 telephone conversations, lasting about 1 min each, included in the Disc r65 _ 6 _ 1. 777 Speakers, of both genders, pronounced a total of 46K …
