How to delete a Siri language/accent

I downloaded different accents for English Siri to try, but now I don't know how to delete them and I won't even be using them. What can I do to delete these Siri accents so I can get my storage back?

I’ve read the answer of:

1. Open Settings > Accessibility
2. Tap on Spoken Content, then tap on Voices
3. Select English
4. Tap on the voice you want to remove, then select Edit in the top right corner.
5. Tap on the red delete symbol

not working, there is no edit button or delete symbol..
