If a sound file can be played from the Files folder, where it is pre-recorded by the Expert Advisor, then the solution of the problem will be real, if the resulting sound file will be integral.
No! The documentation says that sound files should be stored in the Sounds folder.
https://www.mql5.com/ru/docs/common/playsound

This is a critical issue for the topic. If the file won't play from the Files folder, then PlaySound is out of the question. Then there is no need to return anything from the server. Why? Unless PlaySound suddenly fails to work with the EA's internal resource, which I highly doubt...
Someone try running the .wav from the Files folder. I wonder if it works.))

double-checked the song and ran it again

   Sleep(1*1000);
   PlaySound("\\Files\\Sounds\\Kazka.wav");

Well, then you don't always have to believe the documentation)))

Now, if the TC will receive valid audio files from the server, then re-recorded in one place and play on the fly, then the task of universal solution for the voiceover of text messages to the user will be solved.

ZS. Can PlaySound also play the sound from internal resources created by EA? Then there is no need to write the file to Files. Immediately save the file to the resource and play it.

I do not know, in my Expert Advisor - where there is some action, it plays 

                     ObjectsDeleteAll(0,InpObjDownNameG);
                     IndicatorDelete();
                     PlaySound("ok.wav");
                     if(InpChartInd && Obj_SELLChartInd())
                        return;

of course its own melody or sound

Serhii Shevchuk:

I can take a look, but not before tomorrow evening. If you haven't worked it out yourself by then.

Maxim Kuznetsov:

and you won't :-)

why do you put curl command options in HTTP headers?

Why don't you at least read some books, look through some examples... otherwise, we'll all write you an article

so where can i get an example with output to a binary file? ))

trying to figure it out, i've minimized the syntax of the url command itself


curl -X GET -u ^
apikey:GR1bb3zVMs9fcNKL6pA9-5 zj9ptWliCu6eh9oupUnpZB ^
--output hello_world.wav ^
https://api.eu-gb.text-to-speech.watson.cloud.ibm.com/instances/9886a3ce-5734-455f-8f78-7a56381da686/v1/synthesize?text=TEST

i use it to download a wav file with the word TEST in it

then remove options

in the header now is the authorization option -u, behind which the server waits for the apikey. Seems to make sense, but something in the syntax is still wrong

code result -"Webrequest4Voice (EURCHF,D1) Error loading 'https://api.eu-gb.text-to-speech.watson.cloud.ibm.com/instances/9886a3ce-5734-455f-8f78-7a56381da686/v1/synthesize?text=TEST', code 401"

Can you give me a hint? ))

What does error 401 mean?

To translate an HTTP request from curl options to WebRequest parameters, you have to:

1. in general, look at wikipedia to see how HTTP is structured

2. check in Curl documentation to see what options mean and why they are used

3. read the WebRequest help and see examples, even in this thread a lot

4. You should write code being aware of what you've done :-) what, why and why is it used.

You are obviously expecting all 4 points to be done for you. I understand it's weekend, time is short, and you have lots of ideas. It has to be quick.

But you still have to do it yourself.
