Speech Recognition c# [Windows Forms]

Question

In my voice recognition project using c#, I want to highlight the text in the listbox when the word is read so that to be recognized. can you help me?

I assume you have a list box listBox1. You need to use the SelectedIndex property to highlight the text being read. Before switch(word.Text) use this - listBox1.SelectedIndex = listBox1.FindString(word.text); or inside each case use listBox1.SelectedIndex = listBox1.FindString("institute"); and so on.

In the listbox, I wanna highlight the text if it was being read.
