OpenHome provides a Voice SDK and APIs for developers to build custom, LLM-driven smart speaker experiences and conversational AI agents. The platform enables seamless deployment of real-time AI voices and personalities onto custom hardware. It supports complex applications ranging from speech-to-text and language understanding to emotion detection and scheduling.

Problem
Developers building voice‑enabled applications often must stitch together disparate speech‑to‑text, text‑to‑speech, and language‑understanding services, which introduces latency, licensing constraints, and limited control over hardware integration. This fragmentation hampers rapid prototyping of custom smart‑speaker experiences and restricts deployment on proprietary devices.
Solution
OpenHome delivers a unified Voice SDK and REST/GraphQL APIs that expose high‑accuracy automatic speech recognition (ASR), neural text‑to‑speech (TTS), and large‑language‑model (LLM) powered natural language understanding (NLU) in a single package. The SDK runs in real time on edge hardware, allowing OEMs to embed conversational AI directly into custom speakers without reliance on third‑party cloud gateways. Developers can define voice personas, tune inference parameters, and chain capabilities such as emotion detection or instant translation through declarative pipelines. All data streams are encrypted end‑to‑end and the platform provides enterprise‑grade monitoring, versioning, and scaling hooks for production workloads. By consolidating the core voice stack, OpenHome reduces integration effort, lowers latency, and enables consistent user experiences across devices.
Target Audience
The primary customers are hardware OEMs and software teams that need to embed conversational AI into smart speakers, IoT devices, or enterprise voice assistants, as well as SaaS developers building voice‑first applications for domains such as healthcare, education, and home automation.
