Is there a cockpit which can recognize the voice of the pilot and help him/her to fly?
No, voice recognition is currently not used in aircraft as it would have to be built into the aircraft to pass certification for the aircraft and with rotating crews on aircraft, the voice recognition would need to be able to work with too many different voice types: high pitch, low pitch, male, female, accents, dialects and many more factors.

Voice recognition works because it learns from the user over time, something that is not possible in a cockpit environment with crew resource management.

There is a prototype in development by Honeywell at the moment, but it's in early stages of development.
