About Soniox Speech-to-Text
Soniox Speech-to-Text focuses on high-accuracy, real-time speech recognition and translation across more than 60 languages. It targets developers, product teams, and enterprises that need production-ready transcription, streaming, and any-to-any speech translation in a single API. Instead of stitching together separate models for recognition, diarization, and translation, Soniox provides one universal speech API plus a companion app, aiming for native-speaker fluency, strong accent handling, and code-switching support in real conversational audio. Key Features: Universal Multilingual Model: Single API for speech recognition and any-to-any translation between 60+ languages, including mixed-language utterances and dialects. Real-Time Token-Level Streaming: Returns token-level output within milliseconds, keeping captions, voicebots, and assistants tightly in sync with live speech. Context and Domain Adaptation: Accepts hints such as domain, topic, custom vocabulary, and reference documents to improve recognition of medical, legal, financial, or branded terminology. Conversation Intelligence Built In: Handles automatic language detection, speaker diarization, endpointing, timestamps, and confidence scores in a single unified stream. Privacy and Compliance Controls: Offers regional data residency (US, EU, Japan), keeps audio in memory only by default, and is SOC 2 Type II, HIPAA, and GDPR compliant. Soniox App Companion: iOS and Android app for live transcription, translation, summaries, and insights, powered by the same universal speech AI.
