Pros	Emotion-tag control system ([angry], [whispering], [laughing], [pause]) gives fine prosodic steering that most TTS APIs lack Instant voice cloning from ~10-15 seconds of reference audio Voice Library of 2M+ community voices to browse instead of training your own 30+ language coverage across the same models Streaming API with low enough latency for real-time voice agents S1 and S2 model checkpoints published on GitHub for self-hosting Symmetric STT that recognises the same emotion tags used for TTS	Astonishing vocal quality Wide genre range Fast to iterate Lyric + instrumental generation in one tool
Cons	Free tier is explicitly non-commercial - monetised use requires a paid plan Public pricing is opaque - tier prices sit behind sign-in and shift with promos Community-uploaded voices raise consent and IP questions the platform pushes onto the user S2.1 Pro (the best model) is closed - only older S1/S2 are open source Cloning quality on non-English voices is more uneven than on English No native long-form audiobook chaptering workflow - you script and stitch yourself	Copyright/IP questions remain Hard to fine-tune to a specific style
