All out war breaks out between Siri and Google Glass!

Tech rivals are known to counterattack each other through their competitive products, however, Apple's voice search assistant Siri went a step ahead in taking a dig at Google Glass with nasty replies.

If a user addresses Siri with 'Ok Glass'- a command used for Google's Glass, it snaps back replies which include 'I think that Glass is half empty', 'Stop trying to strap me to your forehead. It won't work', 'I'm not Glass. And I'm just fine with that', 'Glass? I think you've got the wrong assistant' and 'Just so you know, I don't do anything when you blink at me'.

On the other hand, Google's wearable computing eyewear Glass would simply search the web when asked about Apple's voice assistant, ABC reports.

However, Google said that the Glass would respond to Siri's nastiness with 'Siri, it's not you, it's me. You see, I just met Google Voice Search and fell hard for her. She doesn't just listen; she understands me'

Apple did not comment on Siri's new responses on Google Glass.
