Amazon Lex
combines speech recognition, text recognition, and conversational interactions to make it easier for
tech companies to integrate voice or text - based chat
interfaces for their apps.
Tech - savvy drivers in the US with, say, a recent - model Toyota, can buy hardware from Comma.ai's website — a dashboard camera, an
interface to the car's electronic systems — and
combine it with the firm's open - source software, openpilot, to create a car that can automatically control acceleration, braking and power - steering systems in specific circumstances, such as driving on a highway.
While there are a few kinks in the
interface and operation, overall, the ZeTime successfully
combines aesthetics and
tech into a rewarding $ 200 package.
