Not getting same list of voices in Speech synthesizer demo

[AIHypnosis]

The Speech synthesizer demo displays Microsoft Natural voices when running it in Edge browser. However, when I implemented the code provided in the example, I was not getting any Microsoft Natural voices in my select list. The issue was that I was testing my code in Chrome.
It took me a while to figure out this discrepancy.

Code example on MDN:
https://developer.mozilla.org/en-US/docs/Web/API/SpeechSynthesisVoice#examples
Speech synthesizer demo:
https://mdn.github.io/dom-examples/web-speech-api/speak-easy-synthesis/
Test it in Chrome and Edge to see the difference in voices selections.

Microsoft Natural voices available in Edge sound naturally in contrary to the voices available in Chrome that sound mechanical.
How can I get Microsoft Natural voice that I like to be consistent in all browsers for my application? Is it possible to serve the voice of choice from the application somehow instead of relying on browser limitations? Please advise.

Thanks!
