Cartesia Sonic-3.6
Sonic is an advanced text-to-speech model designed specifically for real-time voice agents, featuring a natural delivery system with a response time of less than 90 milliseconds and supporting over 40 languages seamlessly. Its primary aim is to facilitate effortless voice interactions, characterized by a tone that adapts to various contexts, a steady pacing, and speech that aligns with the natural flow of conversation. Sonic automatically interprets the emotional nuances within transcripts, adjusting its delivery accordingly, and allows for the direct insertion of non-verbal cues like laughter into the spoken text. Faithful to the original transcripts, the model generates clear audio across different languages and voice options while effortlessly managing alphanumeric data, including order and phone numbers, email addresses, and IDs, without requiring any prior processing. Its context-aware pronunciation ensures that heteronyms are articulated correctly based on surrounding terms, and customizable pronunciation dictionaries empower teams to dictate how specific proper nouns and industry-related terminology should be pronounced. This comprehensive approach not only enhances the quality of interactions but also tailors the user experience to meet diverse communication needs.
