What I was trying to achieve by segmenting the 36 sec file into 3 sec segments was to have a so called "play-by-play" representation of the spectrum to see what's happening, then importing those values into excel or R, and graphing them this way. I'm not sure if this script is achieving my ultimate goal: of getting an Ltas representation (ideally a graph form with dB and Hz axes) of the entire 36 sec of speech file. After running the script, each sound has a corresponding output. Some background: The sound files in the "Folder" directory are 3 second sounds cut from running 3 from 36 sec of running speech, which contains pauses and voiceless segments (I would ultimately only like to run Ltas on voiced regions, which is why I use 'To Ltas (pitch-corrected)' ). And you're right, it would be helpful to see the script wouldn't it. I posted here because it was one of the few questions where I saw 'To SpectrumTier' mentioned, which is a core part of the script I'm using. txt output of my script using "To SpectrumTier (peaks)" reads.

Anyway, whoever wrote your script apparently meant to output a "short text" version of a SpectrumTier, which contains: If the list below is the output of your script, then I can only say it's hard to answer, because your script is not included. interval, string$(.Were you meaning to send this question to the Praat list? It is not clear to me what "this" refers to. The rest contain the tier number of the single speaker Intervals labeled "0" are matched by more than one speaker, in Blank intervals are matched by no speakers in # know where to look for measurements later. We also save the tier number of the (last) speaker, so we # Increment the number of speakers for each labeled coinciding interval # Count how many speakers are speaking over that flattened interval flat_intervals = Get number of intervals: 1 # overlap if and only if there is one tier with a speech labeled interval which A segment in the overlap tier will be considered to have no # Cycle through the flattened intervals to check how many spoken intervals # We use nocheck because there might already be a boundary there # Populate overlap tier with "flattened" intervals from all tiers # Apply the original label to the new TextGridįor archival purposes: # This procedure is a part of the tgutils plugin Original$ = Get label of interval: tier, j # Get the midpoint, to match to intervals in a different # you only want labeled intervals (there will be no zeros) # Since your original TextGrid had no overlapping intervals So after running the example above, you can do # Loop through intervals in the new TextGridįor i to do("Get number of intervals.", 1) The remaining labels tell you the tier number of the only labeled interval that contained them. Unlabeled intervals were not contained in any labeled intervals in old. Each interval in this new tier with a non-zero label will represent a chunk of the old TextGrid contained in labeled intervals in at most one tier. If you include that procedure (either physically copying it or includeing it), you can do old = selected("TextGrid")Īfter that, the new TextGrid will have a single tier will all the intervals from the other tiers "flattened out". The logic of that script is in a procedure that can be included into whatever script you are using (or canibalised into it, if you're into that sort of thing). Although the task is different, the TextGrid that script creates to work on can be used for what you want. Some time ago I wrote a script that was used to find non-overlapping intervals, also in tiers with different speakers. ![]()
