You can do this by writing numbers as words, which helps control how they are pronounced. Additionally, you can adjust the phrasing by using spaces and hyphens to get the desired effect.
Examples:
- "12325" will read as a full number (twelve-thousand three-hundred twenty-five)
- "One-twenty-three-twenty-five" will be read as it is written.
- "One-two-three two-five" will be read as individual numbers with a small pause after "three."
