Speech/Nonspeech Segmentation in Web Videos

Speech transcription of web videos requires first detecting segments with transcribable speech. We refer to this as segmentation. Commonly used segmentation techniques are inadequate for domains such as YouTube, where videos may have a large variety of background and recording conditions. In this work, we investigate alternative audio features and a discriminative classifier, which together yield a lower frame error rate (25.3%) on YouTube videos compared to the commonly used Gaussian mixture models trained on cepstral features (30.6%). The alternative audio features perform particularly well in noisy conditions.
