Use when the user asks for text-to-speech narration or voiceover, accessibility reads, audio prompts, or batch speech generation via the OpenAI Audio API; run the bundled CLI (`scripts/text_to_speech.py`) with built-in voices and require `OPENAI_API_KEY` for live calls. Custom voice creation is out of scope.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Speech Generation Skill Generate spoken audio for the current project (narration, product demo voiceover, IVR prompts, accessibility reads). Defaults to `gpt-4o-mini-tts-2025-12-15` and built-in voices, and prefers the bundled CLI for deterministic, reproducible runs. ## When to use - Generate a single spoken clip from text - Generate a batch of prompts (many lines, many files) ## Decision tree (single vs batch) - If the user provides multiple lines/prompts or wants many outputs -> **batch** - Else -> **single** ## Workflow 1. Decide intent: single vs batch (see decision tree above). 2. Collect inputs up front: exact text (verbatim), desired voice, delivery style, format, and any constraints. 3. If batch: write a temporary JSONL under tmp/ (one job per line), run once, then delete the JSONL. 4. Augment instructions into a short labeled spec without rewriting the input text. 5. Run the bundled CLI (`scripts/text_to_speech.py`) with sensible defaults (see references/cli.md). 6. For important clips, validate: intelligibility, pacing, pronunciation, and adherence to constraints. 7. Iterate with a single targeted change (voice, speed, or instructions), then re-check. …

How to install
mdr add letta-ai/skills/speech@sha256:b3179910f6ad57a6The line at the top of this page pins the label git:20260422.d32735f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
