Pros and cons

Cartesia

Pros

  • Published time to first audio of about 90 ms for Sonic 3.6, suited to live conversation.
  • Free tier with 20K credits per month and a $5 Pro plan with commercial use and instant cloning.
  • One platform covers text-to-speech, speech-to-text and managed voice agents.

  • Ranked first on Artificial Analysis speech leaderboards according to the company.

Cons

  • The free tier has no instant voice cloning, only 2 concurrent TTS requests and no commercial license.
  • Credit-based billing with overage up to $65 per 1M credits can be hard to forecast as usage grows.
  • Independent reviews note a smaller preset voice library than some narrative-focused competitors.
  • Developer-oriented; there is no consumer app and no released iOS or Android app.

Suno

Pros

  • Free plan with 50 daily credits and access to v6-mini

  • Song downloads are capped at 20 per month on Pro and 60 on Premier, with none on the free plan
  • Suno Studio, personas and advanced stem splitting require the $30 Premier plan
  • Music made entirely by AI may not qualify for copyright protection
  • No public self-serve API; Universal Music Group and Sony Music lawsuits against Suno are reported as still ongoing
