Can I automatically find umms, with the goal of deleting them?

It seems that all are umms look the same - surely something can search the volume bar and highlight them in a colour so we can quickly check and delete accordingly?

I've started producing my videos as audio files, then moving them over to Audacity (ver. 2.2.2.).  It ends up being a multi-step process because Audacity doesn't recognize *.M4A files (I use Adobe Audition to convert them to a WAV file).  Once there, I can use "noise reduction" under "effect".  I haven't tried it with "umms", but it does identify and remove breaths like a champ!

This video kind of/sort of explains it, but the maker of this instructional video is using an older version of Audacity. https://youtu.be/79M3LRPgI9M
But it should get you in the ballpark.

Hope that helps!

Audacity can recognize M4a files but you need to add the FFmpeg and Lame libraries. 
You also need to add the libraries if you want to export out audio as mp3 from Audacity.

It's really easy to do.

Also why don't you export out as .wav from Camtasia from the start.

Camtasia can export out audio as  .m4a or .wav.

Here's a tip.

You can just drag and drop a .trec file with audio on to Audacity and Audacity will extract the audio out and put in on a timeline.
Saves a lot of steps if you want to edit a recordings audio before editing in Camtasia.

  The way automatic noise reduction works is you sample the noise. Then, the program removes all of the noise that sounds like that from the audio.

 There are tolerance adjustments but Umm is primarily  the letters "U & M" Which is prevalent in a high percentage of spoken words.

 If you try to remove that sound automatically. It will make your audio as a whole suffer.

 Try not to Umm as much as possible. Edit them out by manually by silencing them . I use Adobe Audition myself.

If you cut out/deleat all the Umm’s err’s and Ahh’s. As the audio squeezes together. The audio will become out of sync with the video rather quickly when you import it back.

That’s why I silence unwanted noise,If I make a cut in the Editor later, everything stays in sync.

 Regards ,Joe

Agreed.  There really is no automatic way to remove ummm's and ahh's.
Best solution is to not speak them and that takes practice and getting comfortable behind the mic.

I too would have to agree that there is no one click magic button to just remove the Uhm' and Ahh's. It is a situation as Joe stated that would most likely cause more issues than help when trying to use Noise Removal for that situation. Audio Editing can take awhile for someone who does not understand how it works and TechSmith has some basic audio editing functions that help but are not what I consider to be on the Pro Levels as a separate DAW (Audio editing software) that was designed for that purpose.
Although I have had some great quality using the Camtasia Audio Editing Tools too if the recording(s) of my narration or as I went along with the video on screen which I generally never do that way. If your mic is placed incorrectly or your background noises are not the greates for the enivronment you are in then those results will also bleed in to your audio. But, that is off of your question subject here.
Anyway, my suggestion would be to practice going by more of a script and leaving those Uhmm's and Ahh's or other things you do not want in your audio recording out of the picture. Just my suggestions here.
Joe is correct on his suggestions and you also have to keep in mind that using the Noise Removal can also bring in some other issues and they are not 100 percent but they usually if used correctly work good. Thanks for posting and let us know if you got your issue fixed or what you had to re-record your video and audio to correct it. Have a great day/night.

I'm trying to find and highlight them - not automatically remove them. It seems they are isolated and a similar shape - so I would think a tool could be developed to do that.

So you are not wanting a tool to automatically remove them as you stated you are not trying to do that. Then I would have to say that the way you are going about it now would be the only way to accomplish that as I have been around audio editing for many years and there is no tools in any of the Pro DAWS that I can think of that will isolate similar shapes as it does not go based off of shapes it is based on what it hears. It would be a dream tool and someone would be rich if that was made inot a software with that capability.
Like I stated I think the way you are going about it now would be your best option but this is just my suggestion. Have a great day/night and thanks for posting back.

I've re-read my original question several times - I can not see where I said automatically remove'?

... I can see I said 'automatically find'

I'm curious.  Deleting the Umm’s is the goal. Correct?

Wouldn’t silencing them automatically be easier, faster?

I’m trying to understand the reason for highlighting them. That’s all.

Enjoy the day, Ginger

So I can find them, review them and make an informed decision.
