Model-Based Reproduction of Articulatory Trajectories for Consonant-Vowel Sequences

We present a novel quantitative model for the generation of articulatory trajectories based on the concept of sequential target approximation. The model was applied for the detailed reproduction of movements in repeated consonant-vowel syllables measured by electromagnetic articulography (EMA). The trajectories for the constrictor (lower lip, tongue tip, or tongue dorsum) and the jaw were repro...

Classification of Thai Tone Sequences in Syllable-Segmented Speech Using the Analysis-by-Synthesis M - Speech and Audio Processing, IEEE Transactions on

Tone classification is important for Thai speech recognition because tone affects the lexical identification of words. An analysisby-synthesis algorithm for classifying Thai tones in syllable-segmented speech is presented that uses an extension to Fujisaki’s model for tone languages that incorporates tonal assimilation and declination. The classifier correctly identifies all of the tones in 89....

Cipher text only attack on speech time scrambling systems using correction of audio spectrogram

Recently permutation multimedia ciphers were broken in a chosen-plaintext scenario. That attack models a very resourceful adversary which may not always be the case. To show insecurity of these ciphers, we present a cipher-text only attack on speech permutation ciphers. We show inherent redundancies of speech can pave the path for a successful cipher-text only attack. To that end, regularities ...
