Physics of Speech
Acoustic Phonetic
-
To analyse sound wave
signal occur within varying
frequencies, amplitudes, duration
Speech Waveform
Air pressure changes:
- Can be heard
- Cannot be seen
- Can be measure
-
Analysis of
Speech
-
-
Can be derived:
- Intensity = A^2
- Energy
- Loudness = Decibel(DB)
- v = f λ
Frequency Domain
Frequency
- Number of waves per second
