![]() –min_vot_length minimum vot length allowed in milliseconds.–window_mark name of the label in your vot window intervals.–window_tier name of the tier with your vot windows.You’ll then run auto_vot_decode.py from the experiments folder with the following arguments: Before you run AutoVOT, make sure to navigate to the experiments folder and set the path to your autovot/autovot/bin folder. Once you’ve set up your TextGrids, wav files, and have created the lists of the filenames + paths, you should be ready to run AutoVOT. These two files need to be placed in ~/autovot/experiments/config/. The TextGrids and wav files need to be in the same order, and each filename needs to be on its own line. If you’d like to create them automatically, see step 4 in the Full Recipe section. The text files containing the paths and filenames to the TextGrids and wav files to be processed can be created manually or automatically. You should make sure that the analysis window provides enough space before the start and after the end for the system to be able to identify the stop release (or burst) and the onset of voicing in the following segment.)Īs mentioned in the list above, the wav file needs to have a sampling rate of 16 kHz and single channel. The windows of analysis are the intervals surrounding the word-initial stop consonant that AutoVOT should process. If you would like to run AutoVOT separately for each stop consonant (e.g., once for “p”, once for “t”, and once for “k” there are good reasons for doing this), then see the full recipe below. If you would like to run AutoVOT in one go, the label of the intervals to be processed should be the same (e.g., “vot” or “stop”). The TextGrid should contain at least one tier with an interval for every VOT to be processed. a text file containing the names and locations (the path) for the wav files to be processed.a text file containing the names and locations (the path) for the TextGrids to be processed.a TextGrid with an interval tier for the VOT “windows of analysis”.To run AutoVOT, you will need the following: At least for pip, I solved the problem in the following way:įirst: install pip by typing the following into the command line (must be connected to the internet). ![]() You might also run into this with pip and possibly also git. I did not have pip installed on my computer, so I needed to install that separately. I was able to follow their instructions up until the pip -r "requirements.txt" command. Note that there are several dependencies that you might have to download separately. You will first need to visit the online tutorial for the prerequisites and basic installation.ĭo follow the command line installation instructions closely. It also offers the option to train your own acoustic models from labeled training data.Īs the online tutorial is extremely helpful, I will just offer a few tips from experience. The system comes with pre-trained acoustic models/classifiers for American English and British English word-initial, prevocalic VOTs. What does it include? AutoVOT can be used via Praat directly or via the command line. With these boundaries, positive VOT can be measured efficiently using a standard acoustic analysis program such as Praat. What does AutoVOT do? AutoVOT takes a sound file and Praat TextGrid marked with the locations of word-initial, prevocalic stop consonants and creates a new tier with boundaries marking the stop consonant burst release and following vocalic onset.
