How to convert text to speech (free projects, services)?

Question

speech synthesis

I want to create an application with the sound of the entered text.
The user enters text, the application reads it.

What services can be used to convert text to speech? Interested in free projects (git)
Maybe something is under Delphi, C#? Well, or javascript (often it is web oriented).
Paid sites are also interesting, with easy registration and minimal cost (this is important). You give them an http request, they give you a file.

I looked at Amazon Polly and Yandex SpeechKit. I liked the quality of the translation.
But, unfortunately, it requires the creation of an account. Of course, you need an account to pay for anything. But the amount of information required and linking the card ... even I somehow don’t want to link a real card, and users, especially, will not go to such difficulties.

What can you advise me?

Answer 1

Google MS SpeechAPI. There are dozens of Delphi examples on the net for working with a standard Windows synthesizer. You don't need to invent anything. Just recently I made a bot for VK on Delphi with just such an opportunity. "TextToSpeech"

Answer 2

How about SpeechSynthesisUtterance in JS?

let synth = window.speechSynthesis;

    document.onclick = function(){
      let speech = new SpeechSynthesisUtterance();
      speech.lang = 'ru-RU'; // язык
      speech.rate = 1.5; // скорость
      speech.text = 'Текст для озвучки';
      synth.speak(speech);
    }
