ADVANTAGE
Why Build Voice AI on TRTC
TRTC's voice AI infrastructure: sub-300ms latency, AI noise suppression, open LLM/STT/TTS providers, and MCP extensibility.
Ultra-Low Latency
End-to-end audio and video transmission under 300ms globally, with conversation latency under 1s — matching human response speed for smooth, natural interactions.
Fast to Deploy
Start from a scenario template in Agent Studio, validate with a live voice session in Playground, and grab ready-to-paste code from the Code Tab — go live in 2–3 days.
Leading Audio Processing
Server-side and client-side AI noise suppression with 3A echo cancellation — toggleable per AI conversation mode for precise, high-quality voice AI calls.
Open Provider Ecosystem
Compatible with leading LLM, STT, and TTS providers. Manage all third-party API keys centrally with API Management — configure once, reuse across every agent.
Precise Conversation Control
Choose between Intelligent Interrupt and Manual Interrupt. Switch between VAD Silence Break and Semantic Break for sentence detection. Fine-tune LLM history rounds and timeout for full control over every conversation.
Extensible via MCP
Connect any MCP Server to give your agent real-time access to external tools and business APIs — bridging voice AI directly with your own systems.
Architecture
From your voice to the agent's response
TRTC routes your voice through real-time STT, LLM inference, and streaming TTS synthesis, built for natural, low-latency conversation at scale.
The Tencent RTC Conversational AI solution includes built-in Automatic Speech Recognition (ASR) and interruption handling, allowing customers to flexibly access specified Large Language Model (LLM) and Text-to-Speech (TTS) model services to create natural and smooth conversational AI features that better fit business scenarios.

Frequently Asked Questions
How does Voice Agent charge?
New users receive 10,000 free trial minutes to experience all features at no cost. After the free credits are used, flexible postpaid billing applies. Total cost consists of three parts: Audio Call Fees + Voice Agent Service Fees + STT Fees. For STT and TTS, you can choose TRTC's built-in options or connect third-party providers; LLM fees are billed directly by the provider. See the Voice Agent Service Billing Guide for details.
Can I integrate Voice Agent into my own applications?
Yes. We provide both UI-based and headless (no UI) integration options, so you can combine TRTC's real-time audio capabilities to build highly interactive voice agent features directly in your product. See the Voice Agent service documentation to learn more.
What third-party STT, LLM, and TTS providers are supported?
STT: Tencent, Azure, Deepgram, Soniox
LLM: OpenAI, DeepSeek, Minimax, Tencent Hunyuan, Coze, Dify, and any provider compatible with the OpenAI standard protocol
TTS: Tencent, Cartesia, ElevenLabs, Inworld, Minimax, Azure, and Custom
