Cartesia

Today, we’re releasing a new model called Voice Changer. Voice Changer transforms an input voice clip into any output voice from your Cartesia voice library. It preserves the vocal characteristics of the input voice: the intonation, prosody, and emphasis. It’s a perfect fit for so many use cases, 1. For creators, record speech exactly as you want, and change to the voice of your choice to make unique and emotive content. 2. For gaming & entertainment, act out dialogs, and use the character voice you love for each dialog to craft the perfect experience in studio quality. 3. For listeners, transform your favorite audiobooks, lectures, and podcasts to bring every character to life with a different voice. 4. For businesses, allow any employee to quickly create studio quality, expressive, and realistic audio that fits your brand and your goals. Voice Changer integrates seamlessly into our platform, and you can use it with all voices immediately starting today.

He also won the US Mathematical Olympiad in 2020. Reflecting on his internship experience at Cartesia, he said "I had the freedom to make key decisions about my project and come up with new ideas, while under the mentorship of world class researchers. I'm excited to be back!"

We're excited to welcome Noah Tye to our technical staff! 🚀 Noah previously led Developer Experience at LiveKit, which provides realtime audio/video infrastructure for AI. Before that, he worked at Stripe and Twitter, and worked on developer tools at Kite and RunKit. "Real-time voice models are cutting-edge technology with clear business applications," he said, adding that writing about himself in third person feels weird. "I'm excited to build the tools for the next generation of tech products." We're excited to share several of the product features Noah is already working on very soon 🎉

It's been awesome to work with Quinn Favret, Hassaan Raza, and team on building lifelike digital replicas! Low latency and ultra-realistic speech are key in this setting.

When Cartesia met Hassaan Raza and team, they were already pushing the limits of AI performance. Tavus had previously faced challenges with auto-scaling and network delays in their existing setup. Partnering with Cartesia has been a game-changer for Tavus. Cartesia's Sonic model, with its consistent sub-90ms latency, has enabled Tavus to simplify their infrastructure while meeting their stringent performance requirements. Here's why Tavus chose Cartesia: ⚡️ Industry Leading Latency: Achieving sub-90 ms response times, Sonic enables Tavus to deliver end-to-end interactions in less than 1 second—3x faster than previous solutions. 🔊 Voice Realism: Tavus team seamlessly integrated Sonic's lifelike speech, resulting in AI conversations that feel genuinely human. 🚀 Simplified Scalability: With Cartesia's robust infrastructure, Tavus overcame previous challenges with auto-scaling and network delays, handling multiple concurrent users effortlessly.
