It targets developers, product teams, and enterprises that need production-ready transcription, streaming, and any-to-any speech translation in a single API.

• ✨ 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.

📌 What Makes Soniox Speech-to-Text Unique?
