Soniox Speech-to-Text

freemium

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.
