The hidden cost of multi-vendor Voice AI
Most voice AI runs on US-hosted compute with separate vendors for telephony, STT, TTS, and orchestration. Even when your customer is local, their data travels halfway around the world and back.
The hidden costs:
• Each vendor adds 300-500ms latency
• Each hop adds failure points and compliance risk
• No single point of accountability
A full-stack voice AI platform
Telnyx owns the entire stack, from telephony to AI, with GPUs co-located at our Sydney point of presence. That means ultra-low latency for clearer, more natural AI conversations.
• One API to build, one bill to pay, one vendor to call
• Local Telephony Engine and AU Numbers
• Local WebRTC Infrastructure
• Local AI Inference: STT, TTS, LLMs
Production-ready Voice AI
Local infrastructure for speed, HD audio for clarity, and dedicated support for scale. Everything Australian enterprises need to deploy Voice AI with confidence.
Sydney infrastructure
4,000+ GPUs co-located with telephony PoP. <500ms round-trip latency. No ocean crossings.
Crystal-clear audio
HD Voice with G.722 wideband audio (16 kHz) and AI-powered noise suppression for natural conversations.
24/7 local support
Award-winning support from our Australian team to help you build and scale.
True data sovereignty for Australian businesses
Most vendors guarantee where your stored data lives. Few control where data travels during calls. Almost none control where real-time compute happens. With Telnyx, everything stays in Australia.
Your stored data stays in Australia. Call recordings, transcripts, and logs are encrypted in Australian data centers. Full control over retention and deletion to meet Privacy Act 1988 requirements.
Voice and customer data stays onshore, both in transit and at rest. Traffic routes through our private network with no offshore hops, helping you demonstrate ACMA compliance and meet critical infrastructure obligations.
Real-time AI runs locally on Sydney GPUs. STT, TTS, and LLM inference happen in Australia, giving you control over data routing to meet industry and government requirements.
