Please help me have a voice engine that can help children to hear words in segmented phonemes

Hi all
I’m trying to build an app that can help children to read better so I think if I can have a voice engine that can pronounce any word in separate phonemes I know that this can be a little bit away from the topics you speak about in your wonderful society but I believe maybe you can help me, here you can see an example
