@Ciprian-Caizar the text to speech is a really nice feature, I whish it was included in the VP19 permanent license. However there is a workaround that works really well. Not so convenient as 365, but it works. I will try to make a tutorial (if I find the time) on how to do this, but basically it boils down to recording "what you hear" in the speakers using the demo site:
pick your language, type what you want, let it play, whilst recording what you hear on your speakers or headphones.
Windows WASAPI is your friend. You could use the free tool Audacity and select audio host: "Windows WASAPI", recording device: "speakers to (Realtec(R)) Audio) (loopback)". Obviously only if you have Realtek audio chip on your computer, and also update your audio drivers to the latest. You need to set the windows sound config recording tab to enable "stereo-mix" and disable any microphone. It is also very important to configure your speaker setup in the playback tab of windows sound config to stereo (I have a 5.1 and that does not work for the speaker sound recording using WASAPI and audacity).
You could even use Vegas 19 own screen recording tool "vegas capture" to record what you hear, disable the video sources (you only need audio).
