Ask HN: Audio-based content creation?

I was reading how someone made 6-figures PER DAY making Excel videos (https://www.theverge.com/22807858/tiktok-influencer-microsoft-excel-instagram-decoder-podcast) and started wondering if creators would benefit from having a platform where they could create content centered around audio.

Speech-to-text (STT): All your words are transcribed in real-time. This supports foreign languages as well. You can even edit the text in-place while you speak.

Text-to-speech (TTS): Supply the text and receive an mp3 audio file with a voice that sounds like yours reading the text. This also supports different languages.

This could be used to create video courses more easily, or add personal flavor to your blog posts. Whether it's teaching React or talking about any topic you're interested in, your voice dictates the creative process.
