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.
8. Save/return final outputs and note the final text + instructions + flags used.

Temp and output conventions

• Use tmp/speech/ for intermediate files (for example JSONL batches); delete when done.
• Write final artifacts under output/speech/ when working in this repo.
