How to build an audio translator for Spanish ⇌ English Translations?

I have been using AI to translate video and audio for more than 7 months now, I realized I wanted to build a software that would work in the same manner as the Wavel AI voice translator online website that I was using but I’d like to build one specifically for Spanish.
The efficiency needs to be on par with this AI that I use but later on I’ll modify it more to be an excellent Spanish ⇌ English audio/voice/video/text translation and voiceover tool.
I’d like a low-code approach, so if you know a repository that could help me in this project, tag it in the comments
