Build Voice AI with ultra-low latency on Australian infrastructure and local support. The only full-stack platform with Australian GPUs, co-located telephony, and authentic local voices to scale with confidence.

G'day sounds better when it is authentic. Preview regional voices from Telnyx NaturalHD and Resemble on Telnyx infrastructure, alongside third-party options including MiniMax, Amazon Polly and Azure on provider infrastructure. Use Telnyx Ultra when the Telnyx-native Voice AI path is the priority.
Most vendors guarantee where your stored data lives. Few control where data travels during calls. Almost none control where real-time compute happens. Telnyx adds Australian storage through Data Locality, Sydney hardware for the default AI engines, and request-level controls to pin inference in region.

Data Locality keeps covered data at rest in Australian infrastructure. Call recordings, transcripts, and logs are encrypted in Australian data centers, with full retention and deletion controls.

Voice media anchors to our Sydney PoP and rides the Telnyx private network. Storage at rest is guaranteed under Data Locality; in-region processing follows the assistant anchorsite on a best-effort basis.

Pin inference to Australia with strict mode, which fails rather than falling back to another region. Voice AI processing follows the assistant anchorsite and is not guaranteed in region yet.

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
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
