SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps production teams turn scripts and performed audio into polished speech deliverables while choosing the right Cartesia voice API, managing realtime and batch workflows, and avoiding rights, privacy, and integration mistakes.

Core Features & Use Cases

  • Production TTS Planning: Select Sonic models, voices, endpoints, output formats, pronunciation controls, and generation settings for narration, ads, explainers, notifications, avatars, and voice agents.
  • Realtime and Transformation Workflows: Design WebSocket continuation flows for streaming LLM speech, timestamped SSE generation, voice cloning and localization, and voice changer workflows that preserve performed timing and intonation.
  • Rights, Security, and QA: Review consent and usage rights, protect API credentials, assess retention and Zero Data Retention boundaries, estimate credits and concurrency, maintain asset manifests, and validate pronunciation, timing, technical quality, and disclosure requirements.
  • Use Case: Create scene-level WAV narration for a product launch, generate word-timed captions through a timestamp-capable endpoint, or repair a choppy voice agent by moving fragmented transcript generation to WebSocket continuations.

Quick Start

Use the cartesia-sonic skill to create a production plan for the supplied script, including model and endpoint selection, voice direction, pronunciation handling, output settings, rights and privacy checks, asset manifest fields, cost and concurrency estimates, and final QA.

Frequently Asked Questions about cartesia-sonic

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do realtime LLM voice agents handle WebSocket streaming and SSE generation?

Realtime LLM voice agents use WebSocket continuation flows for streaming speech and timestamped SSE generation to maintain low latency. Moving fragmented transcript generation to WebSocket continuations repairs choppy audio output and preserves natural conversational timing.

How do I estimate credits and concurrency for batch audio delivery?

Voice cloning and audio production require consent and usage rights review, API credential protection, and assessment of retention and Zero Data Retention boundaries. You must validate disclosure requirements and maintain asset manifests to ensure rights-aware speech generation.

Does voice conversion preserve original timing and intonation during localization?

Batch audio delivery cost estimation involves calculating required credits and managing concurrency limits based on your selected Cartesia Sonic endpoints and output formats. Production planning includes assessing these metrics alongside artifact manifests to validate batch technical quality.

What human QA steps validate pronunciation and timing in generated speech?

Voice changer workflows preserve performed timing and intonation during voice conversion and localization tasks. The process requires selecting appropriate Cartesia Sonic APIs and validating that pronunciation, timing, and technical quality meet human audio QA standards.
