Cartesia designed new model architectures for the Qualcomm Hexagon NPU, bringing full on-device voice through both speech generation and transcription. Running locally on Googlebooks with Snapdragon X Series processors, these experiences can enable lower latency, greater privacy, and reduced cloud dependency.
Cartesia: Real-Time AI Speech Generation on the Qualcomm Hexagon NPU
Voice is rapidly becoming the primary interfaces for AI. Whether interacting with an AI assistant, engaging with a conversational agent, or consuming narrated content, users expect speech that sounds natural and responds instantly. Meeting both bars on-device has been historically difficult.
Cartesia is bringing this capability to Googlebook through its Sonic text-to-speech and Ink speech-to-text models, optimized for real-time conversational AI experiences. Powered by a new class of efficient architectures designed for low-latency deployment, Cartesia enables high-quality voice generation directly on device, where memory and power are tightly constrained.
Rather than adapting cloud-scale transformers to run on edge hardware, Cartesia designed the first set of these alternative architectures directly around the Hexagon NPU.
By running the full end-to-end pipeline on the Hexagon NPU, Cartesia delivers human naturalness and latency below the threshold of human perception (less than 100ms) to power:
- Real-time voice agents and AI assistants
- Personalized narration and reading experiences
- Accessibility-focused speech applications
- Interactive learning and educational experiences
- AI companions and conversational interfaces
Running inference locally enables speech experiences that are more responsive while minimizing dependence on cloud-based processing.
Expanding Snapdragon Mobile Innovation to Googlebook
Cartesia has already invested in optimizing voice AI experiences for mobile devices powered by Snapdragon. As they expand their offerings to Googlebook, they can take advantage of the same AI acceleration technologies that have enabled high-performance AI experiences across the Snapdragon ecosystem.
This creates a natural path for developers to extend AI innovations across multiple form factors while continuing to benefit from:
- Hexagon NPU acceleration
- Consistent AI performance
- Low-latency user experiences
- Power-efficient AI execution
- Privacy-first on-device intelligence
For developers, this means building compelling AI experiences that scale across devices. For users, it means immediate access to powerful AI capabilities directly from Google Play Store.
Building the Future of Voice AI
Qualcomm Technologies' collaboration with Cartesia highlights the growing momentum behind on-device AI and demonstrate how the Hexagon NPU can enable entirely new categories of voice experiences on Googlebooks.
With applications from Cartesia coming soon to Google Play, Googlebook users will gain access to powerful voice-first AI experiences that are fast, private, and powered by the Hexagon NPU.
As the voice AI ecosystem continues to grow, Snapdragon X Series and the Hexagon NPU are helping bring the next generation of intelligent, conversational, and personalized experiences directly to users, wherever they are.
