voiceover-pipeline 0.5.1

Standalone chunked TTS voiceover + Whisper timing CLI

Voiceover Pipeline

Standalone CLI для генерации озвучки + Whisper timing из Markdown-сценариев.

Четыре TTS-провайдера: Polza GPT Audio, Polza TTS, OpenRouter TTS, Qwen3-TTS (GPU). Whisper CPU small — точные тайминги для Remotion-анимаций и субтитров. Agent-grade JSON-контракт: --json, semantic exit codes, manifest.json. Сценарии могут быть plain Markdown или Markdown с frontmatter metadata для provider/model/voice.

Install

Console scripts: voiceover and voiceover-pipeline (both work).

From source

git clone https://github.com/VladimirMonin/voiceover-pipeline
cd voiceover-pipeline
uv sync --group dev --extra timing-whisper
uv run voiceover doctor

First run

• .env is searched in CWD and upwards through parent directories.
• Whisper model (~486 MB) auto-downloads from HuggingFace on first --with-timings. Subsequent runs use cache.
• Qwen-local requires NVIDIA GPU + CUDA drivers (~4 GB VRAM).

API Keys

Create .env in your working directory (CWD or any parent directory — searched upwards):

POLZA_API_KEY=pza_...
OPENROUTER_API_KEY=sk-or-v1-...

Never commit .env.

Golden Command

voiceover generate `
  --provider polza-chat-audio `
  --model "openai/gpt-audio-mini" `
  --script "script.md" `
  --run-id "prod" `
  --json `
  --resume

Recommended production flow: generate paid audio first, then run voiceover timings as a separate step. If you still use --with-timings, Whisper dependencies are checked before the first paid TTS request.

Для Gemini 3.1 Flash TTS podcasts доступен format: gemini-dialogue с двумя спикерами, voice map и inline tags вроде [laughs], [serious], [short pause].

Gemini prompting quick guide

Gemini TTS works best as a directed voice performer, not as plain text-to-speech. Keep instructions separate from spoken transcript: AUDIO PROFILE, SCENE, PERFORMANCE, CONTEXT, then #### TRANSCRIPT.

Synthesize speech for the performance defined below.
The profile, scene, performance notes, and context are direction only.
Do NOT speak them.
Speak ONLY the lines under #### TRANSCRIPT.

### PERFORMANCE
Style: Warm, thoughtful, conversational, emotionally alive.
Pace: Natural podcast pace with small pauses after important ideas.
Accent: Natural Russian speech.

#### TRANSCRIPT
[thoughtfully] Сегодня разберём Gemini TTS, [short pause] и почему хороший голос начинается с режиссуры.

Use English service directions and English audio tags; keep the transcript in the target language. Use PERFORMANCE for global emotion and inline tags such as [thoughtfully], [sighs], [laughs], [gasp], [medium pause] for local delivery changes. For long podcasts, prefer semantic chunks of roughly 250-450 Russian words, or 180-350 words for emotional material.

Do not paste the whole prompt skeleton into the script body. In this project, put direction into style_prompt, vibe, and speaker profile; keep body text as spoken transcript only. See the full guides: docs/skills/voiceover-pipeline/docs/11-gemini-prompting.md and docs/skills/voiceover-pipeline/docs/12-gemini-prompting-templates.md.
