Have there always been mobile phones made with voice recognition functionality?

The first speech recognition software put on a smartphone was Siri. It was added to the iPhone in 2005.

Speech recognition on big computers has been around since the 1960s... but not on mobile devices.

Thank you for responding. Actually according to this:

"By 2001, speech recognition development had hit a plateau, until Google came along. Google invented an application called ‘Google Voice Search’ for iPhones which utilized data centers to compute the enormous amount of data analysis needed for matching user queries with actual examples of human speech."

I don't think that is accurate, and I wouldn't give Google that much credit for speech recognition. The real work was done first by AT&T Bell Labs and then by Dragon (who bought a couple of innovative technologies along the way).

Nuance is a big evil corporation (I worked for Nuance a while back) that buys up all of the speech recognition technologies now. They basically wait until some innovative new company develops something new, and then takes them over. In my not so humble opinion, Nuance is holding back the technology.

You were correct. In the late 20th century ('70s - '90s) and even earlier, it was mostly machines made that had voice recognition functionality.

I did some work for a company called eScription that was kind of cool. eScription did speech recognition for doctors, the doctors used a telephone (at that time a land line) to call a central server. The central server did the speech recognition.

It was a cool company until it was snapped up by Nuance (do you get the idea that I am not too fond of Nuance).

The technology behind Nuance came from Bell labs and we had a few key players from Dragon too.
