Soniox is a voice AI platform offering two primary ways to process speech: an API for developers and a standalone app for individuals and teams. The technology is designed for real-time use, focusing on low-latency streaming across a range of languages and accents.
For developers, the API supports building voice agents, call center tools, and wearable interfaces. It includes features like endpoint detection to identify when a speaker has finished and the ability to provide domain-specific vocabulary for specialized terminology.
Business users can use the Soniox App for tasks like meeting transcription, voice typing, and real-time translation. The platform is designed for privacy, processing audio in memory without storage by default.
Buyers should confirm whether they need the API for product integration or the App for internal productivity, as the pricing models and features differ.
