Usage notes
Although and  are usually used interchangeably, the former steadily replacing the latter in frequency of use, a distinction in meaning has been made by some commentators. As those commentators have it:
 * to "speak a person or entity" is to speak on someone's side or part as their explicitly or implicitly delegated representative.
 * the mayor, I declare this to be our city's fix-up and paint-up day.
 * To "speak in behalf of a person or entity" is to speak in that person's interest, favor, or aid without explicit or implicit deputization, and especially if they are unable to speak for themselves.
 * to plead in behalf of a cause

Historically, was much more common (7:1) in US usage than  with. Nowadays, however, it has been almost totally (30:1) replaced by. Moreover, the remaining usage of does not systematically follow the pattern prescribed by the commentators. Current British usage also shows to be much more common than. Garner's Modern American Usage (2009) suggests that interchangeability is almost completely accepted.
