What speech does

This skill generates spoken audio from text through the OpenAI API using built-in voices. The agent calls it when preparing narrated explainers, lecture recordings, or voiceover tracks. The definition acts as an OpenDesign catalogue entry.

The skill is curated from the upstream openai/skills repository. To run the full workflow with original scripts and assets, you need to install the upstream bundle into your agent's skills directory. Without working OpenAI API access, audio generation will fail.

What it helps with

  • generate spoken audio from text for video voiceovers
  • narrate lecture notes and explainer scripts
  • produce quick voiceover tracks using OpenAI API voices

Example prompts for the agent

  • generate narrated audio for this explainer script
  • run openai speech to voice over the intro
  • create audio for this lecture using tts openai
