no matter what voice I choose it never lets me set the transcription model to "bg" (Bulgarian) even when I choose a voice which literally its preview is in Bulgarian language, e.g. Elana by Elevenlabs (fSxb5mPM1l5zTVVtM3Vb) Any ideas how to resolve this? https://cdn.discordapp.com/attachments/1211484481848873020/1357661551099777145/image.png?ex=67f10459&is=67efb2d9&hm=86aa1598cf80c8e8b7ce1509ab105ba55b1c82194499cc9db68d2056ab7fd58e&
