Cartesia's Sonic models are a leading choice for real-time text-to-speech, prized for very low latency and natural prosody, making them well-suited to voice agents and interactive applications. The API is developer-friendly with a usable free tier (20K credits), pay-as-you-go at roughly $50 per million characters, voice cloning, and clear pricing tiers from Free to Enterprise.
It's an infrastructure product, so non-developers won't use it directly, and heavy voice-agent usage adds per-minute costs on top of TTS credits. Multi-language support is growing but English remains strongest; it's globally accessible as an API with no ASEAN-specific provisions. An excellent pick for engineers building latency-sensitive voice experiences.
