Elevenlabs Api

What this skill does

The Elevenlabs Api skill enables advanced control over ElevenLabs’ text-to-speech (TTS) capabilities within programmatic video and audio pipelines. It supports detailed voice selection by gender, accent, and age from the full voice catalog, streaming TTS for faster audio generation, and real-time synthesis via WebSocket for immediate previews. It also handles pronunciation customization using SSML phoneme tags or a pronunciation dictionary, and implements caching strategies to reduce redundant audio generation and manage API quotas efficiently.

Who it's for

This skill is designed for performance marketers and growth leads working with video content who need precise voice customization and fast turnaround times. SEO and PPC specialists embedding dynamic audio in ads or landing pages will benefit from streaming and real-time TTS features to optimize production speed. Agency strategists managing multi-voice campaigns with complex pronunciation requirements and tight API quotas will find the caching and dictionary controls essential for scalable, consistent voice branding.

Key workflows

Practitioners start by querying the API to list available voices and programmatically select the best match based on attributes like gender or accent. Next, they generate narration audio using streaming endpoints to reduce latency, especially for longer scripts, or leverage WebSocket connections for near-instantaneous previews during iteration. For brand consistency, they incorporate pronunciation dictionaries or SSML tags to override default word pronunciations. Finally, they implement content hashing and caching to avoid regenerating audio unnecessarily, balancing quota usage with production speed.

Common questions

How do I select a voice that matches a specific accent or demographic? Use the voice listing API to filter voices by labels such as gender, accent, or age before synthesis. Can I preview audio quickly during development? Yes, the WebSocket API provides real-time TTS streaming for immediate playback. How can I prevent hitting API limits with repeated text? Implement caching based on a hash of the text, voice, and model parameters to reuse existing generated audio files.

How to use in Metaflow

Attach the Elevenlabs Api skill to any Metaflow agent task that requires advanced TTS beyond basic generation. Expect to configure voice selection parameters, streaming options, and pronunciation dictionaries programmatically within your workflow. The skill handles cache checks automatically to optimize API calls and runtime, enabling efficient and consistent audio production across video or audio assets. This is ideal for workflows demanding both quality and speed.
