A: Hello,

TTS technology includes:
Rule-Based Systems: Use predefined rules for speech generation. Simple but less natural.
Statistical Models: Use statistical data for better quality speech than rule-based systems.
AI-Based Systems: Use AI algorithms for highly natural and conversational speech, offering the best quality.

Once you go to GSpeech homepage: https://gspeech.io
On TTS generator, open the voice panel. The voices with star icon are AI voices. The first voice in the list is non-AI voice.

Thanks! :)
