is there a auto stop/.start feature for recording in premere pro simular to mp3mymp3

does anyone know of a vox plugin for the voiceovers similar to this app so when you stop speaking, it stops recording. this seems like such a simple thing to integrate into a app of this level and this tool has proven useful on long voiceovers as all you do is just literlaly stop speaking, take a moment...and come back and its one audio track. just seems odd that nobody has covered such a basic concept.  the part of mo3mymp3 that i use for this often is called "silence detection" .
