Get ListedSoniox is a real-time multilingual speech AI platform that provides speech-to-text, text-to-speech, and translation capabilities through a single unified API. Designed for developers and enterprises building voice-enabled products, Soniox addresses the core challenge of achieving native-speaker accuracy across 60+ languages while maintaining sub-200ms latency for live interactions. The platform powers use cases ranging from voice agents and wearables to dictation and speech translation, with support for seamless language switching, multi-speaker conversations, and domain-specific vocabulary.
Real-time Speech-to-Text: Transcribe live speech with sub-200ms latency across 60+ languages. The API handles multi-speaker conversations, mixed-language code-switching, and noisy environments without requiring manual language selection.
Text-to-Speech with Precision: Generate natural, high-fidelity speech in 60+ languages with accurate handling of alphanumerics, foreign names, borrowed words, and language switching. The TTS API supports ultra-low-latency streaming, starting audio output from the first few words.
Real-time Speech Translation: Translate spoken content across 3,600 language pairs with low-latency output that begins before sentences finish. The translation engine is optimized for code-switching environments where speakers alternate languages mid-conversation.
Multi-region Deployment: Use the same models and API everywhere with in-region processing to meet latency, data residency, and regulatory requirements. Soniox supports SOC 2 Type 2, ISO/IEC 27001:2022, HIPAA, and GDPR compliance.
Speaker Detection and Diarization: Automatically distinguish between different speakers in fast-paced or overlapping conversations, producing clean transcripts that separate who said what.
Developer-friendly API and SDKs: Get started quickly with comprehensive documentation, a cookbook, and integrations with popular frameworks like LiveKit and Pipecat. The platform offers both streaming and async transcription modes.
Developers integrate Soniox via a single REST API or WebSocket connection. For speech-to-text, audio is streamed in real time and returned as transcribed text with punctuation, formatting, and speaker labels. For text-to-speech, text input is converted to natural speech with configurable voice parameters. Translation combines both: incoming speech is transcribed, translated, and optionally synthesized into speech in the target language. The entire pipeline operates with sub-200ms latency, enabling live conversational experiences.
Soniox is built for developers and product teams at startups, mid-market companies, and enterprises who need to add real-time voice capabilities to their applications. It serves use cases such as voice agents, call center transcription, medical dictation, media captioning, speech analytics, wearables, and multilingual communication tools. The platform is also used by AI labs and global technology companies requiring high accuracy across multiple languages and accents.
