Sonic is incredible! I cannot remember the last time that I was this impressed by a product. The Cartesia team is clearly onto something here. Highly recommend to everyone looking for ultra-realistic generative voice technology

@mashy That's a great point! We're definitely prioritizing (and continuing to work on) expanding the voice options to be maximally inclusive and diverse! We've put in a lot of work to try to expand our training data to make sure a diverse set of voices work well.

Looks very cool! A lot of folks out there are creating voice experiences. It sounds like speed and accuracy (in terms of sounding lifelike) is a big differentiator? Would love to hear a little more from y'all about what you think some of the key features are. Congrats on the launch!

@sg2 Thanks for the great question! One key feature is extremely low latency, compared to other offerings of this quality - this makes it particularly useful for interactive applications (e.g. conversational agents, gaming, tutors). Based on our benchmarks, we also think it has better pronunciation on hard examples (e.g. numbers, dates, acronyms, initialisms), highly diverse and expressive voices, and the ability to design voices (by mixing two similar voices and/or adjusting the emotion and pace of a given voice).

@bclyang this sounds amazing. We're building a wearables-based agent to interpret conversation and provide audio feedback. Will give this a proper look. Thanks

Review Cartesia Sonic?

Reviewers mostly praise Cartesia Sonic for one thing: fast, natural speech that works well in real-time use. The lone user review says it is easy to integrate and notably low latency. Founder feedback from makers of MindPal, Guideless, and Toby adds recurring detail: responsive voice output, strong voice quality, useful multilingual options, and a quality-to-cost balance that held up against alternatives. There is little critical feedback in the reviews provided.
