When selecting a TTS provider, consider the trade-offs between spelling accuracy (pronouncing spelled-out words like “W - O - R - D”), voice naturalness, pacing/tone consistency, and accent support.
These observations are based on our internal testing. Results may vary depending on the specific voice, model, or language used.

Provider Overview

ElevenLabs

  • Best for: Most natural sounding; best support for niche accent needs (e.g., Australian English)
  • Consideration: You may occasionally notice small pacing/tone quirks; less reliable for exact spelling

Cartesia

  • Best for: Natural sounding with stronger spelling than ElevenLabs
  • Consideration: Pacing/tone can sometimes be less consistent than ElevenLabs; localization may be weaker for certain accents

MiniMax

  • Best for: Strongest spelling + most consistent tone (rarely has pacing/tone quirks); great for Asian languages
  • Consideration: Voice sound can sometimes feel more robotic compared to other providers

Rules of Thumb

  • Need most natural sound → ElevenLabs (or Cartesia)
  • Need spelling accuracy → MiniMax (or Cartesia)
  • Need most consistent tone → MiniMax
  • Need specific accents → any provider can work, but ElevenLabs tends to perform best for niche accents
