Male voices are more effective for giving orders.
Female voices are more effective for the delivery of informational messages.
With regards to why certain messages are voiced by males and others by females, MTA spokesperson Gene Sansone said in 2006 that, "Most of the orders are given by a male voice, while informational messages come from females. Even though this happened by accident, it is a lucky thing because a lot of psychologists agree that people are more receptive to orders from men and information from women".. For example, a 4 (NYCS) Bronx-bound train at a station would broadcast, "This is a Bronx-bound 4 express train. The next stop is 125 Street," with a female voice. Before the doors close, a male recording would then announce, "Stand clear of the closing doors please!"
