Hello,

I've noticed that my avatar's voice have changed in the HeyGen API.
I might have a clue about what changed.
I went to the web version of the service and encountered the same issue with Eleven Lab v3. When I set the parameter to Eleven Lab v2, it works again as before.
So, I though the default "model" parameter has changed from Eleven Lab v2 to v3. This is why I specified the modele parameter v2 in my API request to resolve the issue.
Unfortunately, the problem still persists and specifying the model parameter in the API request didn't yield the same result as my voice using the web version.

TECHNICAL DETAILS:

endpoint: POST https://api.heygen.com/v2/video/generate

with voice parameters:

"voice": {
"type": "text",
"input_text": "this is text",
"voice_id": "my_voice_id",
"speed": "1",
"pitch": "0",
"elevenlabs_settings": {
"model": "eleven_multilingual_v2", # << this parameter seems ignored
"similarity_boost": 0.5,
"stability": 0.8,
"style": 0.4
},
"duration": "0.7",
"emotion": "Broadcaster"
}

Please keep me updated.
Thank you in advance,
Hugo
