## What it does

This skill turns a finished post into audio with Gemini TTS. It can produce a spoken summary, a full article reading, or a two-speaker dialogue, then creates an audio file and an HTML5 embed.

Before the first paid call, it states the mode, model, chunk count, and estimated cost, then waits for explicit consent. Long text is split into chunks, and `--max-chunks` has a default cap of 12. Check the limit first, because a full reading can take several paid calls.

It requires Python 3.11+ plus `GOOGLE_AI_API_KEY` or `GEMINI_API_KEY`. FFmpeg converts WAV output to MP3; without it, the skill falls back to WAV. Regular runs do not create `.venv`; only `/blog audio setup` does that.

# Blog Audio: Gemini TTS Narration for Blog Posts

Bundled paths below use host Markdown substitution of `${CLAUDE_SKILL_DIR}`;
it is not an exported shell variable. Resolve them before execution, quote
paths, and refuse nonabsolute overrides. Pass `blog_reference_root` resolved
from `${CLAUDE_SKILL_DIR}/../blog/references`, `blog_template_root` from
`${CLAUDE_SKILL_DIR}/../blog/templates`, and needed sibling roots to agents.
Read the main reference `orchestration-details.md` before loading project
context; pass only its helper-fenced output to downstream agents.

Generate professional audio narration of blog content using Google's Gemini TTS.
Three modes: summary (200-300 word spoken overview), full article read-aloud,
or two-speaker podcast dialogue. 30 prebuilt voices, over 130 languages on
Gemini 3.8 Flash TTS (over 100 on Flash-Lite; Google's speech-generation page,
checked 2026-10-12), HTML5 embed output.

## Cost and consent gate (mandatory, read first)

This skill spends the user's Google AI credit and writes audio files.

- **What it spends:** one paid Gemini TTS call per text chunk. Long text is
  split into chunks, so a full read-aloud costs several calls. The script's
  `--max-chunks` flag caps the chunks per run (default 12); never raise it
  without telling the user the new worst-case cost.
- **Cost basis:** audio output tokens at 25 tokens per second of audio.
  On 2026-10-12 https://ai.google.dev/gemini-api/docs/pricing listed
  `gemini-3.8-flash-tts` at $9.00 per 1M audio tokens (about $0.00225 per 10
  seconds) and `gemini-3.8-flash-lite-tts` at $6.00 (about $0.0015 per 10
  seconds), both through 2026-12-31 with higher listed rates from 2027-01-01.
  Run `--dry-run --json` first for the script's estimate.
- **What it writes:** the audio file under `audio/` (or `--output`) and, in
  setup only, the managed `.venv`.
- **Consent:** before the FIRST paid call in a session, state the mode, model,
  chunk count, and estimated cost, then wait for an explicit yes. The yes
  covers only that run. Writing a blog post does not consent to audio.
- **No uncapped spend:** never retry or loop on paid calls beyond the cap;
  one retry on a transient error, then report.
- **Skips:** if the user declines, the key is missing, or setup is absent,
  skip and return ONE line for the orchestrator's "Fallbacks and skips"
  summary, such as "Audio: no API key set, skipped".
