Pountuation errors in AI service

Question

I manage to complete the transcription perfectly, but I have one small issue, It does not separate after punctuation

For example:

I am transcribing things

I believe we have some power over who we love.It isn't just something that happens to a person.And yes, you can stand there and tell me that the poets would disagree, but I am not a poet.I am just a woman and as a woman I have no way to make money.Not enough to earn a living and support my family.Even if I had my own money, which I don't, it would belong to my husband the minute we were married.If we have children, they belong to him, not me. They are his property.So don't sit there and tell me that marriage isn't an economic proposition, because it is. It may not be for you.But it most certainly is for me.That will be Fred now.How do I look?Do I look alright?

As you can see, it doesn't separate after a . or ?

Thi is my VM
