This revised and expanded edition of the classic "Elements of Acoustic Phonetics" provides a concise introduction to basic concepts of acoustics and digital speech processing that are important to linguists, phoneticians, and speech scientists. The second edition includes four new chapters that cover new experimental techniques in acoustic phonetics made possible by the use of computers. Assuming no background in physics or mathematics, Ladefoged explains concepts that must be understood in using modern laboratory techniques for acoustic analysis, including resonances of the vocal tract and the relation of formants to different cavities; digital speech processing and computer storage of sound waves; and Fourier analysis and Linear Predictive Coding, the equations used most frequently in the analysis of speech sounds. Incorporating recent developments in our knowledge of the nature of speech, Ladefoged also updates the original edition's discussion of the basic properties of sound waves; variations in loudness, pitch, and quality of speech sounds; wave analysis; and the hearing and production of speech.

太淺顯。但Ladefoged的書總要高看一眼的嗯。
评分聲學基礎知識。p6，空氣粒子左右震動。四，幾個正弦波閤成復雜波，spectrum比波形圖更能定義元音，line和continuous spectrum之間關係。五，共鳴，damped，resonance curve，resonant frequency及bandwidth（0.707），作為filter的共鳴器的作用。六，振幅影響音高，音高變化感知最低閾限，主觀音高感知與客觀基頻關係，音強取決於振幅均方根，分貝。七，source-filter理論。八，簡單共鳴腔，two-tube model的前後tube與F1F2，Helmholtz 共鳴器與低F1，成阻部位不同，F2F3交替受圓唇影響。九，采樣頻率及振幅層級，窗口（方形、弧形）。十，離散傅立葉變換。十一，MAfilter，綫性預測係數
评分被老師安利讀的第一本acoustics，循循善誘得相當溫柔。雖然Ladefoged去世瞭，但還是希望能有修訂版。
