Yes, F0 (the fundamental frequency) is the acoustic correlate of pitch (which is a perceptual concept). The fundamental frequency F0 is also the first harmonic H1 of the sound. If F0 is 100 Hz, the second harmonic H2 would be at 200 Hz, the third H3 at 300 Hz, the fourth H4 at 400 Hz, and so on. Vowel formants are located at different harmonics depending on ...

There is no "out-of-the-box" way of drawing the combination of a Sound, Pitch, and TextGrid object, to form something similar to what you see in the TextGrid editor. However, this does not mean that it cannot be done. You can script this command, making use of one of Praat's strengths. Whatever you do, please, do not put screenshots on your papers. Save ...

It is often helpful to avoid voiceless sounds as much as possible in prosody stimuli, to get a clearer pitch track. For example, "Mary will win" has no voiceless sounds (from: Pierrehumbert, J. (2000). Tonal elements and their alignment. In Prosody: Theory and experiment (pp. 11-36). Springer Netherlands.). For demonstration purposes, you may also want to ...

There are enough criteria that the decision is unprincipled, that is, there isn't some unquestionable principle that you can use to deduce where the lines must go, if you are looking for phoneme boundaries. For example, in parsing English [kʰɑɹ], you have to decide whether the velar release burst is the end of the consonant, or do you go for the beginning of ...

Bartlomiej Plichta has written a Praat script which automates your first solution, shelling out to the open-source ImageMagick package to do the colour conversion: http://bartus.us/blog/?p=579 Along the lines of your second solution (using something other than Praat): There were a fair number of free and commercial acoustic analysis programs around before ...

You just need the correct Praat command: "Paint visible spectrogram...". Here is the relevant manual page: http://www.fon.hum.uva.nl/praat/manual/Intro_3_4__Printing_the_spectrogram.html

You was thinking correctly, it is just that this value is the highest amplitude of your visible signal on the window. Whereas RMS (Root Mean Square), like its name indicates it, takes into consideration the average of the amplitudes of your signal. So the RMS value will be always between the highest and the lowest amplitude found in a given interval. The ...

Your spectrogram is not clear. You should use a narrow-band spectrogram to see formants efficiently. So change your settings. To obtain this visualisation, you should use a small window length as it is indicated here: http://www.fon.hum.uva.nl/praat/manual/Intro_3_2__Configuring_the_spectrogram.html After that, if it appears harmonics with a high energy, so ...

Praat only has versions for different OSs and not cor particular hardware. If it doesn't work in version 6.1.08, then... you could try to figure out how to change the display routine. Or mention it to them and it might get on a fix-list.

Pursuant to comments: whenever you use Draw in Praat, always Erase first, since otherwise it uses the previous drawing.

As I understand your question, there are four different tasks: Look for a word in a TextGrid tier Find its last vowel Look for the interval labelled with that vowel in the segment tier Measure something on that interval The first and the third seem to me to be on-topic for this question. 1. Find a label in a tier This is pretty straightforward. The most ...

Having selected a sound object, you look at it via the view and edit button in the Objects window. Select the Formant tab and make the first entry, Show Formants, be checked. You then have to select a small enough stretch (mouse select) and zoom in (^n) so that a spectrogram appears. Otherwise you'll see a blank window telling you about the maximum length of ...

IMPORTANT: As with most properties of speech, the criteria described below are only going to be useful in relative terms--your script is going to do much better the more specifically it can be trained (either automatically or by you feeding it the appropriate parameters as arguments) for a specific individual in combination with a specific recording setup, ...

You need to switch the "focus" of the commands to the editor. The way it's written now, it's trying to apply the "Select" command to the object in the object window. Try: Read from file: "sound.wav" selectObject: "Sound sound" Edit editor Sound sound Select: 0.108, 0.112 Extract selected sound (preserve times) endeditor selectObject: "Sound ...

"Pitch" is the perceptual correlate of fundamental frequency which is the rate of vibration of the vocal folds (in speech). "Intensity" is the perceptual correlate of... I'll say RMS amplitude. There are a lot of things that determine amplitude, such as the openness of the vocal tract. In vowels, Fundamental Frequency (F0) does often correlate with amplitude,...

I'm guessing by "on the fly" you mean you can be speaking into a microphone and seeing a waveform, spectrogram, pitch contour, etc. produced as you speak into the microphone? Praat cannot do this, but WaveSurfer (another free speech analysis program) can. You can decide ahead of time what types of display windows (called "panes" in WaveSurfer) to have open, ...

Use the 'Pitch help' button in the object window when the Pitch object is selected. I'm going to simplify this answer a bit: Pitch estimation is inexact, so those numbers are basically the ranked candidates for pitch (y-axis, marked in Hz at intervals of 100 Hz) at that point in time (x-axis, marked in seconds). If you zoom in a little, you'll see they're ...

There is a limited sense in which F0 (which is the acoustic property perceived as pitch) and F1-F5 are not independent, which is that if you have a tiny larynx (high F0), given the nature of human anatomy you will not have a really long tube (which determines formant frequencies). Another dependency is that resonance frequency can always be meaningfully ...

Describing a /t/ as "glottalized" without including an alternative "glottal stop" may be unwise, because it invites confusion between between a /t/ pronounced like an ordinary [t] but with simmultaneous closure of the glottis (which I would write [tʼ]) and a glottal stop [ʔ], because both are possible. (Also, "glottalized t" in other languages can refer to ...

This line echoes the script version: echo 'praatVersion$'. If you want to check for the current version you sound do: versionPraat$ = left$(praatVersion$, (rindex(praatVersion$, ".")-1)); versionPraat = 'versionPraat$' #convert string to numeric if versionPraat < 6 exit Please download the most recent version of Praat. endif I stole this from a ...

WaveSurfer lets you display spectrograms in color, and it's free. Once you record or import a sound, right-click (or the equivalent) on the waveform pane. Select Create Pane > Spectrogram. The spectrogram will appear in black and white as a default. Right-click (or the equivalent) on the spectrogram and select Properties. Here you can play with all ...

Sonic Visualiser is one of the programs I've been using to view/analyze my audio. It is freeware but it's a pretty decent prog imo. It does have many options to adjust your Spectrogram and a couple other options to get creative with. I mostly use it to listen to my techno tracks ;) Another nice option this prog has is where ever you put your mouse ...

For your purpose, you might want to investigate Forensic Audio Workstation.

You can either downmix it to mono, or delete one channel. choosing one over the other depends on your situation. if your channels are identical you can delete one, if your channels are not identical you can downmix them in one channel so that you will not lose any data. To downmix your audio in Praat go to Convert - Convert to mono To extract one channel, ...


2

In the objects window, choose Convert > Convert to mono This converts your recording from stereo to mono by overlaying the two channels. Then draw as usual. If the two channels differ substantially and you want only one of them (instead of a mixture of both), you can load the recording into Audacity and split the stereo track into two mono tracks.

You divide your class into teams. All of the teams are given the same string that constitutes the same grammatical English sentence--same words, same syntax. Each team tries to endow this sentence with as many different meanings as possible simply by varying the prosody. Rinse and repeat with a different sentence.

The number you get in Query ---> Get Intensity... is the mean intensity of the sound which for the sound file I have is 81.49346601915424 dB when I open the sound file in View and edit and select the whole sound file I will approximately get the same number: The windows showing spectrum analysis : As an alternative you can also select Spectrum ---> ...

My first job as a graduate assistant in linguistics in 1965-66 was in Ilse Lehiste's acoustic phonetics lab at Ohio State, and for a time, I spent many hours running a Kay Sonagraph, making sonagrams (spectrograms) from taped informant sessions. I don't know how the variable bandpass filter was implemented, but you could see what was happening. The ...

I figured it out. I'm sure this seems not very automatic, but it's good for if you want to only measure specific things.
