Please vet my Saas idea — Text To Speech

After brainstorming too much, I have decided to go forward with a text to speech saas idea.

MVP:

For the MVP version, the plan is to offer multiple speakers with a few languages supported at a reasonable price.

I am thinking to integrate chatGPT into same product also, so the user can generate the script, edit it and convert it to speech at the same place.

What do you think?

What do you think, is there still a market for this, will people be interested in paying to use this saas, what more features do you think MVP or the product should have?

Please be as blunt as needed, I am all ears.
