Replaces the voice in a video or audio file with one from the Novoads voice catalog, over the REST API. Converts the SPEECH in the source to a voice you pick, keeps the original timing so lip-sync survives, and returns audio that gets muxed back over the untouched picture locally. Casts by MEASURING the source voice against auditioned candidates instead of reading labels, refuses a source with no speech before anything is charged, fences sound effects and music so they survive from the…
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
# Change Voice One video in. The same video out, with the speech re-performed by a voice you chose. The picture never moves. The timing never moves. What changes is who is speaking, and the entire craft of this skill is in three decisions the endpoint cannot make for you: **which voice**, **which spans of audio to replace**, and **whether the result is actually good**. The HTTP call in the middle is one request. **Every HTTP mechanic here belongs to the pack, not to this skill.** Auth, strict bodies, status codes, rate limits and error envelopes are written out once in [`skills/novoads-api/SKILL.md`](../novoads-api/SKILL.md) and its [`reference.md`](../novoads-api/reference.md). Read those for mechanics; this file names the endpoint and the fields that matter to a re-voice. ## Before anything: this runs on a Novoads account - **Base URL:** `https://api.novoads.ai/v1` (host overridable with `NOVOADS_BASE_URL` — host only, you append `/v1`). - **Auth:** `Authorization: Bearer $NOVOADS_API_KEY`, read from `.env` at the repo root. - **Check:** `./scripts/check-novoads-env.sh`. If it is missing, run `./scripts/setup.sh`. …

How to install
mdr add novoads/agent-skills/change-voice@sha256:bbe7c3507beef4bfThe line at the top of this page pins the label git:20260930.c0004d7, 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.
