Listening to the right human speech creates an INCREDIBLE relaxation response for me. I have never felt so deeply relaxed as when listening to the right speech.

I have tried several sleep aids in heavy dosages, meditation, breathing exercises, visualization/journey exercises and pre-recorded journeys ... but none create such a powerful relaxation response.

Weird, I know! It took me a while to notice how deep and regular my breathing was without effort, and how a deep calm always settled over me when I fell asleep listening to audio such as from The West Wing. Eventually I bought a sleep mask with built-in wireless earbuds, and began experimenting with different kinds of human speech as background for sleep.

Just as @koheripbal discovered, I found the selection of just the right audio is important.
