#GRID ANNOTATIONS IN PRAAT WINDOWS#

(Optional) You can rectify the pulse marks in the pulse marking window using the following keyboard shortcuts:ġ0. You can then used the boundaries in the marked layer as shown in the figure below as the outline to other layers.ĩ. You should add boundaries to the layer with the highest number of interval first, because boundaries in other layers must be synchronous with it. Add boundaries to each layer in the annotation window. It should be noted that in this version of PENTATrainer2, boundaries in all layers must be synchronous with the boundaries in the layer with the highest number of intervals.Ĩ. If you prefer to use existing pulse marking data, they need to copy the pulse marking files to the working folder before running the annotation script. The pulse mark data are stored in the pulse marking files (.pulse). The pulse marking window allows you to rectify the pulse mark in cases where the initial markings are incorrect.

The pitch estimation algorithm in PENTAtrainer2 uses this pulse mark information to calculate F0 rather than using Praat’s pitch tracks. The distance between each pulse mark thus indicates the pitch period which is inversely proportional to the fundamental frequency. The vertical blue lines are pulse marks which specify the locations where the signal appears to repeat itself. The pulse marking window contains only one panel which displays the speech signal in time domain (waveform). You can insert boundaries by using the “Boundary” menu on the top of the window or using the shortcuts as listed below: Panels (1) and (2) help you put in the boundaries of prosodic events in each layer in panel (3). The annotation window shows three main panels: (1) speech signal (waveform), (2) spectrogram and pitch contour (estimated by Praat but not used by PENTAtrainer2), and (3) functional encoding layers. Note that the pulse marking window will only be shown if the “Inspect pulse” box in the “Annotation – Option” is checked, The second window (lower) shows the pulse marking window in which you can manually inspect and change the pulse mark locations.

The first window (upper) shows the annotation window in which you need to put in boundaries of each prosodic event.

wav file, two windows will prompt for your input. If there are no existing markings, you must ensure that the “Copy boundary from” text box is empty. In case you have already marked the boundaries in Praat’s TextGrid format, they can import the existing boundary markings by filling in the filename extension of the existing marking files in “Copy boundary from” and the tier number of the boundary data. In PENTATrainer2, the most labor intensive task in annotation is the marking of temporal boundaries of prosodic events. Each name in the list will be used as a name of the information layer in the annotation files. The format of the text must be space-delimited. In this window, You can specify the list of information encoding layers in the “List of communicative functions” text box. PENTATrainer2 will display the “Pause: Create new annotation” window. “Perturbation length” & “Final offset” and the check box “Set initial time for normf0 to 0” are used only for generating F0 measurements and so do not need to be changed. F0 sample rate indicates the sampling rate of F0 estimation. timenormf0 files (which is useful only for optional graphic displays and has no impact on parameter learning). Number of point per interval specifies the resulting number of F0 points in each annotated interval in the. F0 ranges indicate the possible minimum and maximum F0 values that will be searched. In this window, you can fine-tune the F0 estimation process. If the “Edit F0 analysis option” box is checked, PENTATrainer2 will show the “Pause: Edit F0 analysis option” window. The accuracy of estimated F0 depends on whether the pulses were marked correctly.ĥ. For accurate F0 estimation, pulse marks can be manually inspected by checking the “Inspect pulse” box. You can also edit the F0 analysis parameters used in the F0 extraction process by checking the “Edit F0 analysis option” box. (Both plug-in and script versions) Now select “Create new annotation”. (Plug-in version) Choose the working folder.ģ. (Plug-in version) Open Praat and click on the menu Praat -> PENTAtrainer2 -> AnnotateĢ.
