Voice AI is not only real-time.
Meetings, medical conversations, customer calls, interviews, podcasts, and years of call center recordings all contain valuable information that needs to be turned into structured data for LLMs, search, analytics, and other downstream systems.
Soniox Async STT is built to do this at massive scale.
It doesn’t just return a transcript. It turns recorded conversations into a structured representation of what was said, who said it, in which language, when it was said, and how confident the model is in each token.
Submit recordings up to 5 hours long, provide context about your domain and terminology, and get:
• Accurate transcription across 60+ languages
• Speaker diarization
• Token-level language identification
• Token-level confidence scores
• Precise timestamps
These annotations make recorded conversations much more useful for downstream AI systems, whether you are feeding them into LLMs, building search, extracting insights, or analyzing millions of hours of historical audio.
At about $0.10/hour, even very large archives of recorded audio become practical to process.
