Acoustic and statistical analysis of speech 1500-SZD-ASAM
The laboratory is designed as an introductory course in acoustic speech analysis and cover 8 topics. Each new topic will be preceded by a theoretical introduction, then participants will receive exercises to do on their own based using speech samples. Labs 1-9 include acoustic analysis, labs 10-15 include statistical analysis
● Themes:
● 1/2 Methodology of phonetic research (making a recording, listening to recordings, transcription; acoustic methods; video camera; palatography; electropalatography, aerodynamic investigations, electroarticulography). Introduction to PRAAT (recordings, creating a spectrogram and waveform, segmentation of recordings, SAMPA).
● 3/4 The source/filter model of speech: fundamental frequency F0, the relationship between harmonics and formants, the relationship between articulation and acoustics of speech sounds.
● 5/6/7 Vowel properties (articulation of oral vowels and their acoustic properties: FFT and LPC spectra, formant frequencies, formant plot, duration; vowels in isolation and in continuous speech; vowel variability (target undershoot) related to context, stress, rate of speech; vowels in idiolects; normalization procedure; target model and dynamic model.
● 8/9 Suprasegmental features of speech (stress, intonation).
● 10. Stop consonants. VOT
● 11. Glides and liquids
● 12/13. Sample and population, creating a spreadsheet, data entry and their transformation in STATISTICA, basic descriptive statistics, creating graphs.
● 14/15. Parametric and nonparametric tests (ANOVA, MANOVA, Pillai-Bartlett trace, Mann-Whitney test, Kruskal-Wallis test)
● 16. Summarizing (discussion of projects)
Type of course
Assessment criteria
The completion of the course requires:
- class attendance (allowed one absence);
- done lab’s exercises;
- final project
Students are able to retake steps (exercises and final project) to improve their score.
