VO not pronouncing the new year properly?

I havent experienced this on my i phone 8 running 13.3. I use Alex as my voice and he doesn't seam to have this problem
Maybe it's only a samantha bug?

I'm using an iPhone7 with the default Samantha. She says, January two-thousand-twenty.

Yep, having the same issue as the author running 13.3 on an iPhone 7 using samantha

I haven't seen this, & I use Ava Enhanced as my voice of choice.

Samantha does this on my iPhone X as well.

The Kate voice is doing something similar on macOS.

yep, I'm also experiencing it with Siri female US voice! it says 20th 20 for I don't know what reason!
just checked it in my calendar app!

funny bug

I am using iPhone 8 Plus and it is running iOS 13.3. There is no issue. Siri clearly pronounces twenty-twenty. Using Indian English (female) voice. Probably, you can change the Accent and see if Siri pronounces correct.

I changed Siri accents to British (Female), and still, there is no incorrect pronunciation by Siri.

I use the iPhone XS, 13.3, with original Samantha. She pronounces the year the same as the original author indicated.

Some of the American voices have major pronunciation issues with 13, Samantha being the worst. Been reported to Apple on multiple occasions.
How in capitals reading H O V. Gun spelling G U N. A rather large list.

Hi.

This is being caused by the speech synthesiser trying to be too clever. It is seeing the month name and then a number afterwards, and is assuming that the first part of the number is the date within that month.

Consider the following text:

January 2020

This is the word January, written out in full, followed by a space and then the digits 2 0 2 0. This also works if you just write Jan.

I have several English voices on my phone. The compact ones all say it correctly. The enhanced versions of the Lee and Karen voices both say "January twentieth twenty ".
The worst example I have found on my phone is the UK female Siri voice, which says "the twentieth of January twenty".

This kind of assumption has been around for years, even in eloquence, but this is the worst effect I have ever seen.

The only issue is tom who says January as januar but everything is read correctly otherwise.

The incorrect pronunciation doesn't occur everywhere, so those reporting they aren't seeing the problem might not be encountering the situation where it does occur. As pointed out in comment 13 above, I think it's a matter of the synth attempting to be too smart. If it sees a month followed by a number, it's assuming the number is a day of the month and not the year. So, this happens in the calendar where the month is followed by the year without a day of the month. The year heading is pronounced correctly in the calendar because there's no preceding month in the heading.

Likewise, Siri pronounces the date correctly when asked for the date. Voiceover pronounces it correctly on the lock screen because it includes the day of the month along with the year.

I don't think it's strictly a particular voice, but rather, some of the voices (perhaps the enhanced voices) are trying to be too smart and making incorrect assumptions.

My calander says January two-thousand-twenty, but I think I am using compact Samantha.
Fred says it correctly
Siri Female says twentieth twenty
Funny though, Samantha says milibars instead of MB
I wish screan readers didn't expand abbreviations and roman numerals.
