The AI Text Based Editing tool opens a new window that shows blue track clips representing parts of a clip containing speech. Dragging the blue text clips around splits and moves the part of the video that contains the text. Adobe made a splash with a similar feature in Premiere Pro last year. The Filmora tool has a handy button that removes any silent parts of the video. It also lets you search for spoken words to shunt you right to the part of the video where the word is being spoken so that you can move, trim, or delete it. In my testing, however, it wasn't perfect, cutting off some speech.
