Speech Attributes • This work focuses on integrating together various speech attributes extracted from the speech waveform to perform recognition • A speech feature is any feature extracted from the signal that could be useful for recognition • This work concentrates on using two speech attributes: phonetic attributes and phone class • Phonetic attributes are defined via linguistic properties per the International Phonetics Association (IPA) phonetic chart • Consonants defined by their sonority, voicing, manner, and place of articulation • Vowels defined by their sonority, voicing, height, frontness, roundness and tenseness • Additional features for silence
