What Makes Soniox Stand Out

• Native-speaker accuracy across 60+ languages: Soniox delivers unmatched recognition accuracy for numbers, names, and domain-specific vocabulary in high-noise, multi-speaker scenarios.
• Ultra-low-latency streaming: Transcribe speech with sub-200ms latency and generate audio from the first few words, enabling natural, real-time interaction.
• Seamless language switching: Accurately transcribe and translate conversations where speakers switch languages mid-sentence, with support for 3,600 language pairs.
• Privacy-first design: Audio is processed in memory and never stored, with SOC 2 Type II, ISO 27001, HIPAA, and GDPR compliance.
• Single unified API: One API for speech-to-text, text-to-speech, and translation, with in-region processing for data residency.
