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	Strong arrangement quality Multiple style controls Affordable More granular composition controls than Suno
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	Slightly behind Suno on vocals (subjective) Smaller community
