Chapter 6-acoustic Characteristics Flashcards
What is frequency
The number of cycles of vibration per one second also perceived by pitch
What is intensity
The amplitude of energy or loudness
What sounds are more intense
Vowels and diphthongs.
What is a waveform
A graphic representation of sound that displays time on the X axis or the absciss and intensity on the ordinate or Y axis
What is a spectrogram
A graphic representation of all three major physical parameters time frequency and intensity
If you have greater intensity do you have lighter or darker bands
Dark
Do voice or voiceless consonants have a longer VOT
Voiceless
What do fricatives appear as on a spectrogram
Wide bands of energy continuous noise and there the highest frequency phonemes
What are the most intense of all the fricatives
Sibilants
Will voiced or voiceless fricatives appear darker on a spectrogram and why
Voiceless will be darker due to greater intensity
What is a formant
Defined as a resonance of the vocal tract
The duration of any phoneme depends upon what
Whether it is a stressed syllable the phonemic context of the syllable or word that contains the phoneme and the importance of the meaning of the word that contains the phoneme
Our fricatives higher or lower in pitch then vowels
Higher
Our vowels longer or shorter induration and fricatives
Longer
Nasal formants have lesser intensity than vowel formants due to what
Anti-residence and damping
