Can I make myself sleeptalk more?

I'm really into dream recall but lately I haven't recalled my dreams even though I tell myself throughout the day to remember my dreams.
I have the full version of dreamtalk Recorder on my Iphone. Sometimes I sleeptalk, but I don't seem to say much lately either. I was wondering if there's a way to train myself to sleeptalk more often. I know that other people who use the ap speak out loud a lot, and if i was to speak out loud when I dream, it would help me to remember the dream when I heard the recording back.

NO ; you can train yourself to sleep walk

Talking in sleep is a disease which need cure not to develop any further. As long talking in dream it may simply be highlighting your need improve your communication skills or learn to express yourself more
