Voice-First AI Agent Platform

Everything you need to build, deploy, and scale LLM-powered voice agents

Interaction Flow Designer

Map out how your agent handles conversations — greetings, intent routing, escalation, and handoffs. Define branching logic visually so the agent always knows what to do next.

Knowledge Base Access

Connect documents, FAQs, and product catalogs. Your agent pulls relevant answers in real time so it responds accurately instead of hallucinating.

Agent Personas & Voices

Give each agent a distinct personality and voice from 2M+ options. Match your brand tone — professional, friendly, multilingual — and keep it consistent across every call.

Multilingual Support

Agents that speak 8+ languages natively. Serve global customers in their preferred language without building separate agents for each region.

Telephony & Web Integration

Connect to phone systems via SIP or deploy on the web via WebRTC. Replace IVR phone trees with natural conversations your customers actually want to have.

Tool & API Integration

Let your agent take action mid-conversation — look up orders, book appointments, update CRMs, trigger webhooks. Connect any API and the LLM decides when to call it.

Voice Agents for Every Team

Replace hold music and phone trees with AI that actually solves problems

Customer Support

Deploy agents that answer product questions, troubleshoot issues, and escalate to humans when needed. Handle thousands of calls simultaneously with zero wait times, 24/7.

Sales & Lead Qualification

Qualify inbound leads over the phone with natural conversation. Your agent asks the right questions, captures details, and books meetings — so your sales team only talks to hot prospects.

Call Centers & Telephony

Replace rigid IVR menus with voice agents that understand natural language. Route calls intelligently, handle common requests end-to-end, and cut average handle time without sacrificing quality.

Multilingual Customer Service

Serve global customers in their native language with a single agent. No need to hire multilingual staff or build separate support lines — one agent, every language, every time zone.

Frequently asked questions

A voice agent is a conversational AI that listens to users via microphone, understands their intent, and responds with a natural human voice in real-time. Fish Audio's voice agents combine speech recognition, language understanding, and our text-to-speech technology into a single deployable unit.
Use the visual flow editor to design your agent's conversation logic, upload documents to its knowledge base, select a voice from our library of 2M+ voices (or clone your own), and deploy with a single URL. No code is required for basic agents.
Voice agents connect via WebRTC for browser-based voice calls or WebSocket for server-to-server integration. This means you can embed agents in web apps, mobile apps, phone systems, or any platform that supports real-time audio streaming.
Yes! Agents can invoke external APIs and tools during conversations — look up databases, book appointments, process payments, trigger webhooks, and more. Configure tools in the agent settings and the AI decides when to call them based on conversation context.
Every agent gets a built-in test suite. Define conversation scenarios with expected function calls and run automated tests to validate behavior. You can also test with live voice calls directly from the dashboard before deploying to production.
Voice agents are billed at 20 credits per second of active conversation. During the beta period, all costs are reduced by 50%. Check our pricing page for credit packages and plans.
