Smallest.ai
Smallest.ai delivers the world's fastest AI voice technology with sub-100ms text-to-speech and real-time voice agents for enterprises.





What is Smallest.ai
Smallest.ai is an AI voice platform that provides the world's fastest text-to-speech technology and intelligent voice agents. The platform's core product, Lightning V2, can generate 10 seconds of natural speech in just 100 milliseconds, making it significantly faster than traditional voice synthesis tools.
The platform offers two main solutions: ultra-fast text-to-speech for converting text into realistic voices, and AI voice agents that can handle customer calls, support inquiries, and business automation in real-time. Users can clone voices from just 10 seconds of audio and create custom voice experiences across multiple languages.
Designed for enterprises, the platform integrates easily through REST APIs and runs efficiently with less than 1GB of memory, making it suitable for everything from mobile apps to large-scale contact center operations.
