Frequency Bar Spectrum Options

[i440forums]

Hy, I'm a language teacher and I'm trying to visualize pitch changes in audio tracks for spoken sentences, in order to show the phrasal stress to my students.

For the moment, this is what I do :

using sonic visualiser, I'm using the pYin pluging (monophonic pitch and note tracking) from Matthias Mauch with stems as plot type. I'm doing this on an audio file which speed I have reduced by 60%. It shows me the "bumps" in the pitch. For some sentences this works fine, like this one :

but many times, I'm getting very hatched images, like this one :

So I'm looking for a way to visualize the pitch in a different way, without white spaces between certain letters, f.ex. like a presentation in bars, like an equilizer :

It doesn't have to be real-time analysis, I just want a static picture.
Can this be obtained by any means?

Any program which does the job is fine with me.
Thanks for your help...

fascinating. unfortunately, your image links dump me to a general pinterest type page, not useful. but...pYIN shows solid bar segments, lines basically, of pitch, and breaks that bar when sounds that have quality, but not much pitch information, like hard consonants, etc. that's basically the way all the pitch correction software we use work, too. i think you may have more luck with the sonogram type analysis tools that ornithologists use to visualize bird song. the Macaully (sp?) library of ornithology is a great example of this. interesting problem.
