Mix speech and noise using praat
Просмотров 1,6 тыс.Год назад
Mix your speech and noise using this Praat script. This video tutorial explains the basics of mixing speech and noise, and covers some important considerations to keep in mind as you create sounds for an experiment. We also give examples of how to use the various functions of the script to adjust signal-to-noise ratio, impose modulations on the noise, add leading and trailing time, and saving t...

Resonance in a water pitcher
Просмотров 2,3 тыс.3 года назад
Resonance refers to the frequencies that are facilitated by the dimensions and properties of a vibrating object. As you pour water into a pitcher, you can hear the resonance change, since the length of space between the water and the top of the pitcher changes. Note: the drawings starting around 5:02 are just done by hand and aren't to scale. Also, the standing waves would emerge differently be...

Can anyone tell, why we are learning it? I meant the objectives or implications?
16:29 differences in frequency means change of place of articulation 17:15 voiced sound has voicing bar, periodicity in voiced fricatives
I'm very grateful for your video. Excellent explanation!
Thank you very much, the video is clear and concise, and the script was given directly. It is great and solved the problem that has troubled me for several years!
Best explanation! It helps me a lot!
Great video.
I simply copied the code onto the script and ran; a file named Step was generated and the folder too, in the sound file directory, but no normalized sound files were generated; the intensity_info file was empty. What could have probably gone wrong in my case?
it's possible that your sound files don't have the .wav extension (it looks only for .wav files) or that the file path was not typed correctly?
@@listenlab_umn I found out the problem, thx! Its that my sound files are .WAV and the script can only look for .wav 😄 A lot of thanks and a cordial salute!
that actually blown my mind

Why the code cannot be applied? Nothing changed after I clicked run
👏👏❤❤
I wonder if you show me how to do with annotation and segmentation of stops both plain and labialized in the context of initial and intervocalic positions.
Wow!!!! That's SO COOL!!! Thanks for this class! I'm really interested in the visual representation of the differences between standard pronunciation and accent. I want to help "nerdy" ESL students visualize that although there's variation in spoken English as a "lingua franca", such variation has limits and that's why pronunciation is so important. (Do you know any references on that? I'd really appreciate any tips. I'm a newbie in this field).
Thank you for your code & video!!
if you are not dealing with a very large number of data, and suck at coding like me. just use google sheet or even desmos to make the chart in the end.
I am trying to do this myself and whenever i get to the df <- read.csv("my_formants.Table")... comes up I get an error saying Error in make.names(col.names, unique = TRUE) : invalid multibyte string at '<fe><ff>' In addition: Warning messages: 1: In read.table(file = file, header = header, sep = sep, quote = quote, : line 1 appears to contain embedded nulls 2: In read.table(file = file, header = header, sep = sep, quote = quote, : line 2 appears to contain embedded nulls 3: In read.table(file = file, header = header, sep = sep, quote = quote, : line 3 appears to contain embedded nulls 4: In read.table(file = file, header = header, sep = sep, quote = quote, : line 4 appears to contain embedded nulls 5: In read.table(file = file, header = header, sep = sep, quote = quote, : line 5 appears to contain embedded nulls I was wondering if anyone else had this problem and if so, how do I resolve it?
that looks like the kind of error that could happen if you didn't save the formant table as a csv (it's easy to accidentally save it as a different kind of file)
hi, sorry for asking but can I know why when I get the intensity from the 'query' button is different with the intensity i get when I select view & edit -> intensity -> get intensity ? I got 71.10 when i used the query but i get 70.75 when i used this method (view & edit -> intensity -> get intensity)
6:13 this band-pass filter speech sounds like people speak in the old tv shows/radio. Is this what gives the old tv/radio's audio its signature 'voice profile' compared to how we hear people speak in modern tv and real life? I also assumed they do that filter to reduce the data, but since bandwidth is less a issue today, we stop doing that filtering.
yes, I suspect that is part of what makes older recordings sound old. Also, the media on which they were recorded was likely not originally digital, so every transfer of data probably lost some detail (which would be more noticeable in high frequencies)
@@listenlab_umn thanks!
great, which software is it?

I taught myself English. After 20 years of practice I finally have a solid native-like accent. I'm moving to Paris and I'm teaching myself French, and this time I want to nail a native-lie accent (in this case Parisian) using a more rational approach. I just created a "standard" vowel space by following this tutorial and using recordings of a guy online who has a very similar voice to mine, and I intend to compare my own vowel space so that I can improve. Thank you so much dude!
Problem is you have two sounds named "pack" but it only exports one file with that name
Dear Dr. Winn! Fabulous teaching. Do you have any tutorials on Automatic Speech Recognition too?
Thanks for your video and script! Your script works pretty well with affricates. However, one thing I'm curious about is that, when dealing with stop consonants, I find that the middle-lag sounds sound weird, as if it were a pure vowel sound without any initial consonants (for example, ba sounds like a). May I ask the reason for this and how to correct it?
thanks a lot!!
감사합니다 교수님 이거로 제 미쿠쨩 발음을 쫌더 또렷하게 할 수 있겠어요😃
2:09 I'm an English learner. I can't pronounce 'B' 'D' 'G' 'V' 'TH(The)'. Could you amplify the real sound of the that pre-voice of the negative VOT?
Big thanks, its an amazing experience completing this great course.
baritone sounds good. But vocal fry sounds like darker version of baritone for women 😅
Thank you so much, the way you explain everything makes me wanna learn more. ❤
How did you extract the high frequency energy from the original sound? And how to add that with the manipulated sound?
Muchísimas gracias!! esto aceleró mucho mi trabajo doctoral !

I've been using Lingwaves in my masters degree for vocal pedagogy and this is a similar tool that works on Mac. You're an excellent instructor. How do you work out the S/Z ratio in Praat?
Thank you
This is my favorite lesson in your whole series. Thank you very much. You're a great teacher❤
Thank you very much , a great job explaining each and everything clearly
Doesnt this vowel mapping on graph affected by individuals voice
f = c/L. So yes, frequency is inversely related to vocal tract length. Bigger people have deeper voices.
Thank you so much for the useful videos. Is the minimum pitch equal to the fundamental frequency?

Man, I can't thank you enough for making me understand this.
The same here! This is a very good content
thank you so much , I really appreciated it
great video
What is this application R?
Nope, Praat.
@8:56 I would replayed the video in slow motion, and I still can't detect the missing 50 ms pulse.
Hi, It was great, thank you. Have you ever prepared some clips on the wavelet analysis as well?
There's a step at 7:49 that appears to be done with a keyboard shortcut. This is when you told R Studio to read the table of formants. As I'm new to R, I don't know what you've done and how to replicate it. Something similar happens at 9:20, where you told R Studio to take the end points of a trajectory. Could someone please explain how to do these steps?
I was working on a PC and pressed ctrl+enter to run the lines of code that were selected. There's a similar shortcut for mac computers as well, but I don't know what the button is.
Thank you@@listenlab_umn ! I really appreciate you taking the time to respond. I made a chart of my own vowels following your instructions. :)
I’m glad I found this. Thank you so much for sharing. It has helped me in my thesis on speech analysis.
Sorry for the rudimentary question. Does the sampling rate of every audio file used to generate noise have to be the same? Furthermore, do the noise and the signal have to have the same sample rate if I should combine them?
yes, if you are ever combining or concatenating multiple sounds, you definitely want them to have the same sampling rate. I would recommend equalizing that rate before using any script on them
amazing video
omg you're such a good prof
