How do I Convert numbers to text?

You mean with these numbers:

1511 => isloe

1279 => intag

example like that, right?

And you want to convert from 4 digits and more only, right?

The link OP provided explains it a bit better:

0=o, 1=i, 2=n, 3=m,4=k, 5=s, 6=b, 7=t, 8=f, 9=g

1. 2 digit numbers with 0 or 1 are pronounced as they are, for example 17=it.
2. other 2 digit numbers get an “a” in between the numbers, for example 45=kas
3. twin numbers like 22, 33, 44 are pronounced with an oe-sound (like in shoe), for example 22=noe, 33 =moe, 44= koe ; this provides important variation in sounds.
4. 00 and 11 are pronounced as poe and loe for practical reasons.

Here is my quick attempt:

Maverick1912 Something is wrong with your version. Try checking with examples from that link:

4533441690 = kasmoekoe ibgo
7712674491 = toein batkoegi
0632552199 = obman soenigoe
4201667451 = kanoi boetaksi
0900231141 = ogpoe namloeki
