    Spoken Audio Forge

    Example session with this skill installed

    I have a product walkthrough script in docs/onboarding-walkthrough.md and 14 short support prompts in support-lines.csv. Please turn the walkthrough into numbered MP3 narration segments with a calm, trustworthy tone, and render each support line as its own WAV file with a clear, unhurried phone-menu delivery. Use the cedar voice for the walkthrough and marin for the support prompts, keep every chunk under the per-request character limit, and drop the final files into the standard output folder with a record of the exact settings used for each clip.

    • Read your context and instructions

    Summary

    Rendered the onboarding walkthrough as 4 continuous MP3 segments and all 14 support lines as WAV prompts; manifests cleaned and per-clip settings logged.

    Next steps

    • Listen to walkthrough-002 — the acronym "SPRV" may need a pronunciation note
    • If the support prompts feel rushed, change only pacing and re-render the batch
    • Files are in output/spoken-audio/; keep the instruction specs for future re-renders
    • Disclose synthetic voice wherever this audio is presented as a human narrator

    About this skill

    The problem

    Generating high-quality, professional text-to-speech for product demos, IVR systems, or narration often requires tedious manual tweaking and custom scripts. Developers face challenges with inconsistent pacing, fragmented batch processing, and hit-or-miss tone control across multiple files.

    What it does

    • Synthesizes scripts, CSVs, or articles into professional audio clips using OpenAI Audio API models.
    • Handles long-form content by automatically segmenting text into chunks under 4096 characters to prevent truncation.
    • Executes batch jobs via JSONL manifests for consistent generation of multiple prompts or lines.
    • Applies steerable delivery specs to control affect, tone, pacing, and diction for specific contexts like accessibility or sales.
    • Manages local file organization with stable, sortable naming conventions for reproducible workflows.

    Frameworks & tools

    OpenAI Audio API (GPT-4o mini TTS), Python openai library, and uv for package management.

    Why this beats prompting it yourself

    This skill provides a structured CLI-first approach that ensures auditability and reproducibility. It avoids the common pitfalls of ad-hoc scripts by enforcing hard constraints on character limits and API rate-limiting while providing standardized templates for tone and pacing that go beyond basic text prompts.

    Use cases

    • Creating voiceovers for product walkthroughs and explainer videos.
    • Generating numbered IVR prompt sets for phone menus and support systems.
    • Producing accessibility readouts for long-form articles or documentation.
    • Batch processing localized UI strings into spoken notification clips.

    Known limitations

    Does not support voice cloning, custom voice enrollment, or real-time streaming. Limited to built-in OpenAI voices. No post-production editing or music mixing capabilities.
