How can I send a .mp3 to play through my mic?

[ejected]

I want the text to speech to go through my mic so that people who are in a voice channel with me will hear the text to speech.

I don't know how else to explain it... I really don't. I don't mean to sound rude or mean or condescending or whatever I understand you guys are just trying to help me, but maybe if you guys aren't native Americans translate it to your native language? Again don't mean to sound like a poopy face or whatever, but maybe that will help?

Here are some alternative explanations of what I want to do/worded a bit differently:

- play a .mp3 through my microphone (on Discord/TeamSpeak/Skype/other voice comm programs) instead of speakers.
- play a .mp3 through my VB Audio Cable (which is a different playback device I have, OTHER THEN my default one. [see this screenshot: https://i.imgur.com/R5tUECr.png)
- play .mp3 music through my microphone (on Discord/TeamSpeak/Skype/ect)
- play .mp3 to my default RECORDING DEVICE. INSTEAD OF PLAYBACK DEVICE. [ https://imgur.com/a/Phe7zE1 ]
- play .mp3 to a SPECIFIC PLAYBACK DEVICE. NOT MY DEFAULT ONE. (while not changing it to default. For example, you know how you can change your recording device on Skype/TeamSpeak/Discord ect? Like that.) [Example of another program that does this: https://i.imgur.com/IMVXRvO.png - See how you can choose a specific playback device? This is what I want to do. I want to choose a specific playback device to use instead of my default one.]

- Change the playback output device of this voice1.mp3 TO A SPECIFIC PLAYBACK DEVICE. NOT MY DEFAULT WINDOWS ONE:

from gtts import gTTS

 
t2s = gTTS(text="Hello this is the text to play", lang='en')
t2s.save("voice1.mp3")

to a device other then my default one. (again to this: https://i.imgur.com/R5tUECr.png)

- Make this play voice1.mp3 THROUGH MY RECORDING DEVICE (microphone) INSTEAD OF MY PLAYBACK DEVICE (to one of THESE: https://i.imgur.com/AO4Vx5p.png)

from gtts import gTTs
 
t2s = gTTS(text="Hello this is the text to play", lang='en')
t2s.save("voice1.mp3")

Any ONE of those methods in the explanations above is enough. I don't need all of them. Just one should work.

to inject this sound where the mic sound is going? if the latter, where is the mic sound going?

Yes. This is what I mean. The mic sound is going to any voice recording software/program/game. (For example: Skype call. ANY program that records the mic)

So I managed to get this to (maybe) work but now I'm getting this error. How do I get pygame to use that audio driver?

from gtts import gTTS
import os


t2s = gTTS(text="This text", lang='en').save("lastplayed.mp3")

from pygame import *
os.putenv('SDL_AUDIODRIVER', 'vbaudiovacwdm')
mixer.init()
mixer.music.load("lastplayed.mp3")
mixer.music.play()

while mixer.music.get_busy():
    time.Clock().tick(100)
