Alexa’s big AI revamp may have just been delayed, again – and it sounds like Amazon’s assistant is getting dumber rather than smarter.

Though the updated version of Alexa was originally expected to land in late February, it is now pegged for March 31 or later.

Amazon delayed the release of its Alexa upgrade again after testing flagged problems with incorrect responses.

The release of Amazon's artificial intelligence (AI)-based voice assistant 'Alexa' has been postponed until at least March 31. It was originally scheduled to be unveiled on the 26th, but the schedule was delayed due to issues with inaccurate responses discovered during the testing process.

Concerns over accuracy lead to another delay for the souped-up virtual assistant — but the launch showcase will still go ahead.
