Bixby Voice, Samsung’s English version of its digital assistant will be delayed again because it lacks enough big data to teach it to work properly.

It was supposed to launch in late April before being pushed back to June. With that deadline passed, it’s still unclear when Bixby will be launched.

Samsung did launch parts of Bixby in April in the US, but the components that enable voice to control Samsung’s new Galaxy S8 phone are still only available in Korean

Bixby will compete against Apple’s Siri and Amazon’s Alexa in an industry that sees speech as the next significant step to interacting with devices.
