ElevenLabs: eleven_english_sts_v2

The Eleven English v2 Speech to Speech (i.e. Voice Changer) model is an English-specific speech-to-speech model developed by ElevenLabs. Its core function is to convert any recorded source audio into another completely identical sound while fully retaining the emotions, intonation, and expression details of the original performance. The official description states that it can capture whispers, laughter, crying, accents, and subtle emotional cues, achieving a highly realistic and nearly human-like effect.
