![]() This is the 'acoustic measure extraction' script I would alter if I was to attempt (2) or (3). if vowel followed by vowel, extract value from entire region) Here's the script I'm currently working with. 1) Find an automatic aligner that does the consonantal & vocalic segmentation 2) Create a Praat script that will use the boundaries and labels from the 'phones tier' to create a new 'intervals tier' with consonantal C-intervals and vocalic V-intervals (might require looking at the pronunciation dictionary the Montreal Forced Aligner uses to create phone labels?) 3) Specifying in the Praat script (for acoustic measure extraction) which consecutive labels on the 'phones tier' to extract from? (e.g. Possible solutions I've thought of (not sure if they're all executable). This Praat script will merge tiers of different TextGrid dirs, which tiers you can choose freely. One caveat to note when making consonantal and vocalic boundaries: When a liquid /l, r, w/ precedes or follows a vowel, I want these segments to be included in the same vocalic interval ( /l, r, w/ + vowel ). I'm looking to automate the segmentation and labelling process for consonantal and vocalic intervals. This manual segmentation becomes very laborious for data-sets with large amounts running speech. ![]() The DFTs are averaged using time-averaging (Shadle 2012). Commenting your scripts is always good practice. Spectral moments of fricative spectra script in Praat which extracts the first four spectral moments (center of gravity, standard deviation, skewness, and kurtosis) as well as the global intensity and duration for each fricative. In most cases, programmes that allow for scripting have a 'Run' button (Praat has one). However, for consonantal and vocalic intervals, I had to manually create a separate tier labelled 'intervals' and create boundaries between consonantal and vocalic regions (I referenced the phones tier for this). Run the script: A script needs to be told that it’s time to do the work. I used the Montreal Forced Aligner which provided me with word and phone level alignments, resulting in two tiers (see image below)- 'words tier' (top) and 'phones tier' (bottom). To extract accurate values for these measures, my script must ONLY extract from intervals with voicing, not consonantal intervals. The command uses 6 arguments: the tier to process, the beginning and the end of the point/interval range to process ( 0 meaning all items), the string to match and its replacement, and whether the match should be done using regular expressions. My end goal is have one Praat script use an annotated TextGrid with an tier labelled 'intervals' (containing consonantal & vocalic intervals) to extract various acoustic measures (F0, F1-F5, intensity, jitter, shimmer, Harmonics-to-Noise Ratio) from a corresponding. Where every consonantal interval is labelled 'C', and vocalic interval 'V'. comments are always welcome Wendy Elvira-Garcia Free script under a GNU General Public License contract. 2) Write the folder and the number of tier you want to remove. In the upper menu select Run and Run again. Is there an automatic aligner that will align/segment based on consonantal and vocalic intervals, where consecutive consonants or vowels are grouped into one interval (e.g. 1) Open the script with Praat (Read from file.), the script will open.
