Soniox

Soniox Speech-to-Text AI is the world’s first universal speech API, delivering instant, real-time transcription and translation across 60+ languages with native-speaker fluency. Designed for developers, global enterprises, and professionals, it eliminates the need for complex, patchwork speech systems by accurately recognizing natural conversational flow, mixed languages, and specialized terminology instantly. You can finally build voice applications that truly understand speech, not just transcribe it.

Key Features

Soniox is built to handle the complexity of real-world global communication, offering precision and speed that traditional speech systems cannot match.

🌍 Universal Speech API

Deploy globally without complexity. Soniox provides a single, unified API for all 60+ supported languages and features. This unified approach eliminates the need to manage separate models, integrate multiple services, or rewrite code for global deployments, drastically simplifying your architecture and accelerating time-to-market.

🔄 True Real-Time Any-to-Any Translation

Experience true conversational fluidity across language barriers. Soniox delivers the world’s first true real-time, any-to-any speech translation, continuously streaming mid-sentence translations between any combination of 60+ languages. Unlike systems that wait for full sentences, this low-latency approach keeps conversations natural and synchronized.

🗣️ Native-Speaker Fluency and Low Error Rates

Achieve reliable data capture regardless of the speaker’s background. Soniox captures every word precisely with proven lowest error rates, accurately recognizing dialects, accents, and subtle phrasing across all supported languages. This precision is crucial for critical applications where a single misheard word can change the meaning.

🧠 Contextual and Domain Intelligence

Ensure high accuracy in specialized fields. By leveraging Domain Intelligence, Soniox instantly adapts to specific contexts (e.g., healthcare, legal, finance) using hints, reference documents, or prior conversational context. This capability delivers more consistent and context-aware recognition, ensuring the right terminology and phrasing are used every time.

🔠 Mixed Language and Alphanumeric Recognition

Handle complex, natural speech patterns seamlessly. Soniox instantly recognizes every word in the correct language even when speakers blend languages (code-switching) within a single sentence or phrase. Furthermore, it precisely captures alphanumeric codes, product names, and unique identifiers exactly as spoken, down to the last digit and character.

Use Cases

The precision and versatility of Soniox enable transformative applications across various sectors:

1. Powering Global AI Assistants and Bots

Utilize high-speed, token-level output streamed over WebSocket to build fast, responsive conversational AI assistants and bots. Because Soniox stays in sync with the user's speech in real-time across 60+ languages, you can deploy agents that understand complex queries, handle multilingual customer service, and deliver fluid, human-like responses with minimal latency.

2. Specialized Documentation and Compliance

In fields like medicine or law, accurate terminology is non-negotiable. Soniox is HIPAA-ready and allows you to define custom terminology and translation controls, ensuring technical terms, clinical phrases, or legal jargon are transcribed and translated exactly as intended. This is ideal for medical dictation, legal deposition transcription, and complex compliance documentation.

3. Enhancing Personal and Professional Productivity

The Soniox Mobile App transforms how you manage conversations. Whether you are a journalist interviewing a source, a student in a lecture, or a professional in a meeting, the app captures every detail in real time. It automatically summarizes key takeaways, highlights action items, and organizes all recordings into a searchable library, allowing you to focus on the conversation, not the note-taking.

Soniox distinguishes itself by solving fundamental challenges that limit traditional speech recognition systems, offering verifiable benefits centered on accuracy, flexibility, and privacy.

• Unmatched Language Flexibility: Unlike many providers that struggle when users switch languages mid-sentence, Soniox’s unique mixed-language recognition instantly handles code-switching, ensuring uninterrupted transcription fidelity in multilingual environments.
• Built for Privacy-Critical Use Cases: Security and privacy are foundational. Soniox is SOC 2 Type II–certified and HIPAA-compliant. Crucially, audio data is processed in memory and never stored or saved—a vital feature for highly regulated industries and sensitive communications.
• Simplified Global Deployment: By offering the world's first true universal speech API, Soniox eliminates the operational burden of managing separate regional models or language-specific infrastructure, streamlining development and maintenance for global applications.

Conclusion

Soniox delivers the foundational accuracy, speed, and flexibility required for the next generation of global voice applications. Stop compromising on multilingual performance and start building with the confidence of native-speaker fluency and real-time responsiveness.
