But this workflow is pretty useless for projects already created in Premiere Pro CC 2014. You can't open projects made from 8.1 in 7.2.
Speech Analysis should still be present in CC 2014.1 (8.1). It was removed in CC 2014.2 (8.2).
If you created a Project in 8.2, you could possibly try exporting as EDL or AAF and then import that into 7.2.2. Your mileage may vary with this.
