Pick from a roster of built-in voices ranging from bright and conversational to calm and narration-friendly, then hear the same line delivered differently.
Add a short natural-language direction such as "speak slowly and warmly" to influence tone, pace, and emotion without changing the script itself.
Paste a paragraph or a full script and stream the synthesized audio immediately, with no signup, install, or configuration step.
Switch voices, styles, and wording back-to-back to judge which combination fits a voiceover, audiobook, or product demo.
