IntegrationsBuild Voice AI Agents With Vision Agents and Telnyx
The Telnyx plugin for GetStream Vision Agents now covers the full voice AI stack: PSTN phone calling, LLM, STT, and TTS, all from a single install.
Conversational AI100 Voice AI Tips for the Rest of 2026
100 production rules for AI voice agents based on real deployments: call scope, latency, speech recognition, tools, evals, handoff, safety, and operations.
Conversational AIHow Telnyx Fixed Voice AI Latency with Co-Located Infrastructure
Most voice AI feels robotic because of latency, not bad voices. Every network hop adds delay. We fixed it by colocating our GPUs with our telephony core, cutting response times sub second and making conversations feel human again.

Telnyx STT vs Deepgram vs ElevenLabs on Phone Number Accuracy
We ran the same audio clip through Telnyx STT, Deepgram Flux, and ElevenLabs Scribe v2. Listen to the difference in phone number dictation accuracy.
TTS APITTS architecture decides what breaks first
Text-to-speech models do not only differ by voice quality. The architecture underneath the voice determines latency, cloning quality, streaming behavior, controllability, and cost.

How to build a Voice AI product that does not fall apart on real calls
Explore why most voice AI fails in production, what a real system must do end-to-end, and how to measure success using job-level metrics and reliable escalation.
VoiceBuild outbound AI calls with Python and OpenAI Realtime
Build outbound AI calls with Python, Telnyx Media Streaming, and OpenAI Realtime. Includes Call Control, WebSocket bridge, and PCMU audio.
Conversational AICanary Deployments for Voice AI Assistants
Telnyx AI Assistants now support end-user targeting on top of percentage traffic splits, so teams can test new voice AI agent versions on real calls before widening a canary.
Conversational AIHow we built multi-participant voice AI calls
Adding a second human to an active voice AI call breaks assumptions your conversation layer has held since day one. Here is what changes in the audio layer, the transcript state, and the tool design when you build for multiple speakers.
STT APIHow I built a voice dictation app for macOS using Telnyx
A full breakdown of building a Wispr Flow alternative on macOS using Telnyx STT and LLM inference APIs — pipeline architecture, permissions, hotkeys, and real-world latency.

How to evaluate Voice AI the way real conversations work
Learn the five metrics such as TTFA, E2E, barge-in, and others that explain why your voice AI feels slow on real customer calls.
Conversational AIThe Math Behind Voice AI ROI
Most voice AI evaluations start with cost per minute. That framing almost guarantees the wrong conclusion. Here is a 4-step framework to model the actual economics, plus an interactive ROI calculator to run your own numbers.
