I am looking for leading research reviews and state of the art on speaking and/or listening? In addition, I will be grateful if you could refer me to leading research on communicative approach in the first language teaching?
Regarding the art of speaking, are you interested in rhetoric? There are many classical forms of classical rhetoric over multiple cultural contexts, and of course studies of politicians' use of rhetoric.
If your interest in the art of speaking & listening is pedagogical, you might find the following References of use to you:

Thank you very much Dr Falih Al-Emara and Dr Jinan F. B. Al-Hajaj for your referral. And thanks to you Dr Christine Nicholls as I am interested in pedagogical research.
