Is SAM (Text to Speech) free to use commercially?
SAM Text to speech in spanish
Videos
I'm not entirely sure how to phrase my question properly, so I'm not sure if I make sense. I'm not that familiar with the Commodore 64, so I figured I'd ask here. Maybe my reasoning below could further explain what I mean.
I have an idea for a video and want to use the C64 SAM voice module (I like how it sounds), but I'm not sure if there's some kind of copyright protection associated with it or if it's a public domain/CC0 thing.
Does anyone know if there's an old school text to speech tool like SAM that generates a bit-crushed voice in spanish?
This a web based version of SAM:

I somehow got hold of this when I was 10 to 12 years old. You could run it with basic programming. It was really cool.
It was weird but you had to load a separate module for vowels. Otherwise it couldn’t speak the and they would just buzz.
On Windows about the best I have found was using the speech API and voices from AT&T Natural Voices: https://nextup.com/attnv.html They are however VERY expensive if available at all. I have run into projects where the usage/business model was so far from what AT&T was thinking of that they wouldn't even sell a license.
There is a free software alternative, Festival: http://festvox.org/ , the quality though is horrible. It is about 10 years behind the current sound quality of commercial systems. It is however free.
A third alternative which has worked well for me was to shift the voice synthesis part of a few projects to OS X. OS X has a decent set of tools and speech APIS and a fairly decent set of stock voices. The downside of course is that prorams written for these APIs run only under OS X which runs only on Apple hardware.
AT&T Natural Voices engine produces great speech but its not free
there is also NeoSpeech which are also good - Not free as well
