Mix speech and noise using praat
Просмотров 1,4 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...
Equalize sound durations in Praat

Resonance in a water pitcher
Просмотров 2,2 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...

    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?

    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).

    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.

    • @listenlab_umn
      @listenlab_umn 5 дней назад

      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)

    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!

    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?
