Smallest AI — Real-Time Voice AI Platform (Text-to-Speech, Speech-to-Text, Speech-to-Speech & Voice Agents) Smallest AI is a real-time voice AI platform that provides low-latency text-to-speech (TTS), speech-to-text (STT), speech-to-speech (S2S), and small language models (SLMs) for building production voice agents and multimodal AI applications. It is built for developers and enterprises that need accurate, sub-second voice processing at scale, with self-serve API access and enterprise deployment options including on-premise and private cloud. Core models and products - Lightning (Text-to-Speech): A text-to-speech model that generates studio-quality speech at approximately 100 ms latency, built for real-time voice agents. It supports voice cloning — instant cloning from 5–15 seconds of audio and professional cloning from longer samples — across 15+ languages. - Pulse (Speech-to-Text): A speech recognition model that transcribes audio across 30+ languages with speaker detection and emotion detection, available for both pre-recorded and real-time streaming transcription. - Hydra (Speech-to-Speech): A native speech-to-speech model built for production conversational AI, processing voice directly rather than chaining separate transcription and synthesis steps. - Electron (Small Language Model): A sub-3-billion-parameter small language model designed for fast, task-specific reasoning in voice and agent workflows. Key capabilities - Real-time, low-latency voice synthesis and transcription for live conversational agents - Instant and professional voice cloning - Multilingual TTS and STT with accents and dialects - Speaker and emotion detection in transcription - A voice agent builder for configuring agents by voice, language, and use case - Self-serve APIs with usage-based pricing, plus enterprise plans with custom concurrency and SLAs Who uses it Smallest AI is used to build voice agents and voice-enabled applications across industries including healthcare, debt collection, real estate, e-commerce, customer support, and small business operations. Common use cases include automated outbound and inbound calling, AI receptionists and front-desk agents, voiceovers and content narration, and multilingual customer service. Deployment and security Smallest AI offers cloud, on-premise, and private cloud deployment. The platform is SOC 2 Type 2 compliant, ISO 27001 certified, GDPR compliant, and HIPAA compliant, with a HIPAA zero-data-retention option, making it suitable for regulated and high-trust environments. Enterprise plans include a 99.99% uptime SLA, SSO, and role-based access control (RBAC).
