Invented and non-English names are the TTS failure case. Phonetic respelling that works across engines, and which providers take pronunciation markup.
Cartesia's Sonic 3.5 hits sub-90ms latency across 42 languages and fixes the reads that break TTS: numbers, codes, emails. What that actually buys creators.
ElevenLabs shipped chunk-based Music v2 and a performance-preserving Dubbing v2, then retired its v1 speech models. What changed, and how to match briefs.
Chaining one TTS call per line produces two monologues stitched together. One call that reads the whole script sounds like an actual conversation.
Sounding natural is a low bar almost every TTS model clears in one line. The attributes that actually separate voices only show up over a full script.
ByteDance's Seed Audio 1.0 collapses TTS, music, and foley into one model with zero-shot cloning. How it works, and practical patterns for using it on Versely.
Transcription covers 165 language codes. Dubbing covers 25. Six TTS engines each cover a different subset. Here is the real coverage picture, snapshot dated.
Three tools all get called a custom AI voice, but only two persist. A practical comparison of voice design, instant cloning, and Cartesia fine-tunes.
The best ElevenLabs alternatives in 2026, compared by job: voice cloning, narration, video voiceover, and why multi-provider access changes the math.
