For the second straight year, Google is expected to use its annual conference for software developers to push its latest hardware. Wednesday kicks off Google I/O, the company's developers conference. It starts with a keynote address at 1 p.m. eastern, during which Google is likely to reveal lots of news about both its latest wave of gadgets and its software. Here's what to expect on Wednesday: Amazon's Echo fueled a surge in interest for both voice-enabled speakers and the digital assistants that power them.
