Any ideas on practicing what tone of voice to use based on one's own everyday voice?

[Saga Not Saga]

Hi.  Every Saturday i head to a local mall to see if it can meet someone for the purposes of dating or at least making friends.  I've been doing so for a long time, but recently over the last week or two plundered the prospect of one recording his or her own voice as a means of practicing introducing oneself.

I wanted to know if anyone could point me in the right direction since ones own voice plays a massive role in his or her personality.   Not just introducing oneself.  Infact getting in the habit of adapting a new common voice tone should influence ones of personality i guess.
