Re-Voice IVR Prompts on Phone-Tree Config Merge
When a phone-tree config change merges in GitHub, regenerates the ElevenLabs audio for any prompt whose script changed in the diff and opens a follow-up PR adding the new audio…

- OutputOpen follow-up PR wiring in new audio pathsGitHub
What it does
Treats the IVR phone tree as code. When a pull request that edits the phone-tree config (script strings and node names) merges to the main branch, the workflow reads the diff, synthesizes audio for each changed prompt, uploads the clips, and opens a follow-up pull request that wires the new audio paths into the config.
When to use it
Use this when your IVR definition lives in a Git repo and product renames arrive as config edits. It guarantees the spoken audio is regenerated and version-tracked alongside the text it came from.
How it works
- 1A merged pull request touching the phone-tree config file triggers the run.
- 2A GitHub action fetches the diff and extracts prompts whose script text changed.
- 3A logic step skips no-op edits like reordering and keeps only altered spoken lines.
- 4ElevenLabs synthesizes the changed lines to audio files.
- 5An action uploads the audio to Dropbox and records the resulting paths.
- 6The output step opens a follow-up pull request updating the config to point at the new audio files.
