# Introduction

> The most reliable platform to build voice AI agents.

Phonic is the platform for building, evaluating, and deploying voice AI agents that sound
like a real conversation. Our state-of-the-art speech models feel genuinely human with
real emotion, timing, and nuance.

Every agent you build gets:

* **Sub-500ms latency** between speech-in and speech-out
* **Natural interruption handling** for real back-and-forth conversation
* **Accurate pronunciation** of URLs, emails, and alphanumerics
* **Enterprise readiness** with HIPAA & SOC2 compliance, backed by a 99.9% uptime SLA
* **Usage-based pricing** starting at \$0.15 per minute of conversation

## Get started

To start building, you need a Phonic account and an API key.

* **Phonic account** — sign in or sign up at [phonic.ai](https://phonic.ai)
* **API key** — create one on the [API keys page](https://phonic.ai/api-keys) and store it in `.env.local`

## Build

See the [API reference](/api-reference) for the full surface.

#### [TypeScript SDK](/docs/get-started/installation/typescript_sdk)

Install the SDK and make your first call.

#### [Python SDK](/docs/get-started/installation/python_sdk)

Install the SDK and make your first call.

#### [CLI](/docs/get-started/installation/cli)

Drive the API from your terminal.

## Build with AI

Point your AI assistant at `https://docs.phonic.ai/docs/get-started/overview.md` to have it start building for you.

> **Tip**
>
> Every docs page is accessible as clean markdown for token-efficient parsing — append `.md` to any URL.

#### [MCP Server](/docs/get-started/installation/mcp_server)

Connect Claude Code, Cursor, or Codex to manage your workspace.

#### [Agent Skills](/docs/get-started/installation/skills)

Give your coding agent specialized Phonic knowledge.

#### [LLM Index](https://docs.phonic.ai/llms.txt)

Point your agent at a full index of these docs.

## Example use cases

Phonic agents are already handling conversations like these in production:

#### Customer Service

Field support inquiries — order or booking changes, refunds, account changes, and escalation options.

#### Recruiting

Conduct structured real-time voice interviews, evaluates candidates against role fit, and fits into hiring workflows.

#### User Research

Conduct qualitative user interviews with open-ended discovery, neutral probing, and no leading.

#### Patient Intake

Run patient intake, confirms or reschedules appointments, and hands urgent cases off to a nurse line.
