- Acoustic Phonetics
- The branch of phonetics concerned with the physical properties of speech sounds, including their production, transmission, and perception as acoustic signals. Acoustic phonetics uses techniques such a…
- Jitter and Shimmer (Voice perturbation measures, Cycle-to-cycle variability)
- Acoustic measures of voice quality that capture short-term irregularity in the vocal fold vibration. Jitter is the cycle-to-cycle variability in pitch (fundamental frequency), while shimmer is the cyc…
- Landmark Detection (Acoustic Landmark Detection, Stevens Landmark Theory)
- Landmark detection is a speech analysis method based on Kenneth Stevens' acoustic model of speech production, which identifies perceptually significant points in the acoustic signal where listeners ex…
- Landmark Theory (Stevens Landmark Theory)
- A theoretical framework in speech science developed by Kenneth N. Stevens proposing that listeners extract phonetic information from acoustically abrupt events called landmarks in the speech signal. L…
- Spectrogram (Sonogram, Spectral Display)
- A spectrogram is a visual representation of the frequency spectrum of a signal as it varies over time, typically showing time on the horizontal axis, frequency on the vertical axis, and intensity repr…
