How we evaluated each TTS tool
To make the comparison fair, every product was measured against the same checkpoints:
- Voice realism and variety – Do the neural voices sound natural and are there enough styles to match different content types?
- Language coverage – How many languages and accents are available on the free plan?
- Usage limits – Character caps, daily quotas, or time-based restrictions that affect production.
- Ease of use – Is the interface beginner-friendly and can you export MP3/WAV quickly?
- Commercial usage – Are you allowed to monetize the generated audio without extra licensing?
- Pricing upgrade path – What happens if you need more usage or advanced features later on?
