> ## Agent Instructions
> To search or read these docs, connect the Ringg docs MCP server at https://docs.ringg.ai/mcp (no key needed; tools search_ringg_ai and query_docs_filesystem_ringg_ai) instead of browsing pages one by one. Setup for each client: https://docs.ringg.ai/resources/mcp-server/docs-mcp-server/mcp-for-ai-assistants.md
> The dashboard labels agents "Assistants"; these docs say "agent". Both mean the same object, identified by agent_id.
> API base URL: https://prod-api.ringg.ai/ca/api/v0. Send the workspace API key in the X-API-KEY header, from server-side code only.
> Placing a call dials a real phone number and spends credits. Confirm the number with the user before calling.
> To act on a Ringg workspace (place calls, edit agents, read transcripts), use the separate Ringg workspace MCP server at https://mcp.ringg.ai/mcp: https://docs.ringg.ai/resources/mcp-server/workspace-mcp-server/overview.md

> List the voices you can give an agent, with their supported languages, preview audio and gender, optionally filtered by one or more language codes.

# List Voices

export const RelatedTopics = ({items}) => <div className="not-prose mt-12">
    <div className="text-sm font-medium text-gray-500 dark:text-zinc-400 mb-3">Related topics</div>
    <div className="flex flex-col gap-2.5">
      {items.map(([title, href]) => <a key={href} href={href} className="flex items-center gap-2.5 text-sm text-gray-700 hover:text-gray-950 dark:text-zinc-300 dark:hover:text-white">
          <Icon icon="file-text" size={16} color="currentColor" />
          {title}
        </a>)}
    </div>
  </div>;

Pass the chosen voice's `id` as `voice_id` when you [create an agent](/api-reference/agents/create-agent) or change its voice.

## Notes

* A voice works only in the languages listed in its `languages`. Pairing a voice with a language it does not support returns `400`.
