Monday also marked a much lower key launch for a rebranded (and renumbered) free automated Directory Assistance service, Bing 411. Details on the revamped service can be found here. There are many similarities between Bing411 and the erstwhile “Live Search 411” (which was accessed through the toll-free number 800-CALL411/800-225-5411) which, in turn, had leveraged much of the heavy lifting and automated speech application development that Tellme Networks had undertaken over the past five years or so. Yet there are many noteworthy, incremental and evolutionary improvements.
