Balabolka for converting texts to audio files

 Just tried a couple of Web apps for converting texts to audios: Murf.ai, and Speechify: 

Plus: 

- the resulting speech sounds quite natural

Minus: 

- once you want to download the audio to your computer, it asks you to upgrade. 

+++++++

I then tried Balabolka, a desktop app: 

Plus: 

- It's open-source; it's free to download the generate audio

Minus: 

- the resulting speech is not natural enough

++++++++++++++++

I finally got back to my Spotify episodes, which are converted from my Wordpress blog via postcaster.spotify.com (formerly Anchor.fm). 

The audios are natural enough, but the steps for downloading an episode as an MP3 file are slightly complicated.
