Document Summary
The relationship between the acoustic, production and classi cation of speech sounds. Maximal onset principle: some sounds are mostly at the beginning of a syllable. Stress: longer duration, higher pitch and greater intensity. Vowel quality can change also: some vowels can only occur in stressed syllables, some only in unstressed ones. What kinds of information do waveforms show: time (x axis) and amplitude (y axis). The darker the spectrogram is, the greater the intensity. If there is silent, we see white on the spectrogram. Respiration: almost all speech produced is produced as a result of air going through. Differences in breading for speech vs for life. Ratio to inhale and exhale: longer exhale for speech (10% inhale and 90% exhale) Location of air intake: when we breath for life we breath from our nose and when we breath for speech we breath through our mouth.
