Voynichese is a numeric cipher?

[oshfdk]

I used the script to encode a simple phrase in English. Could you time how long approximately it will take you to decode it?

or an /// chol iin chor o /// qo qo ey iin an in oke y y /// ch o /// chor an in oke y y /// cph y oke y oke y /// ch cph y o ey iin an in oke y y /// che ey in /// chor ch o in y /// ch eor cph y cph y q or an in an in oke y iin /// cph y o ey iin or in /// chol iin chor o /// chol iin ey in y /// cph y cph y ey in ey in oke y oke y oke y in /// ch ch an in y /// an in oke y /// o ey iin oke y iin /// an in oke y /// y /// chol y eor ey iin y

Also, I see /// marks here split the words. I don't think there is something similar in the Voynich MS. Is it possible to decode the cipher without these extra marks? I've encoded another phrase and removed /// marks, how quickly can you decode it?

o ey iin oke y chol iin oke y chol y ey iin an in oke y an in oke y chol y eor y chor ch o chol y ey iin ey y ey or an y y an in oke y ey in oke y iin y ch o ey iin y q ey iin oke y qo ey y oke y iin y ey iin or ch an in oke y ey in ey y or oke y oke oke o an ch an in oke y ch eor cph y o an oke y
