I know Adobe Connect launches its separate application but is there a way to change the speed (ie 2x) in the application or some other way?
You can download the page contents including the voice file.
1- Open in the web browser. Then just append
/output/content.zip?download=zip
to the page URL and press enter.
2- Extract the downloaded file. The file with a similar name to 'voip.flv' is the voice file.
3- You can open it with vlc or any other player and make benefit of the speed option.
Example:
If the link is like:
https://connect.labla.la/p9lhdwnhnf89/?session=breez7b98svagh3mqtkqb&html-view=false&proto=true
you can download the content with this link:
