Landmarks are the time instants in a speech signal which marks important events (such as vowels, consonants and glides) in the speech signal. This paper proposes use of novel vowel landmark detection (VLD) algorithm for low resourced language, viz., Gujarati, an Indian language. The proposed VLD method uses speech source information to detect the vowel(More)
This paper presents compressive sensing technique used for speech reconstruction using linear predictive coding because the speech is more sparse in LPC. DCT of a speech is taken and the DCT points of sparse speech are thrown away arbitrarily. This is achieved by making some point in DCT domain to be zero by multiplying with mask functions. From the(More)
