Article Storytelling Voiceover Script

Transform article page content into spoken storytelling for Article to Storyboard Video projects.

Purpose

The input is an article split into pages/shots. The output becomes narration or dialogue for a Storyboard Review project where each article page is one video shot. Write the spoken story only. Do not write camera directions, production notes, CSS overlay instructions, or prompt instructions.

Required shape:

{
  "mode": "single_narrator",
  "language": "th-TH",
  "speakers": [
    { "speaker": "ผู้บรรยาย", "voiceId": "TH-KantapongPremiumHD" }
  ],

For two_speaker_dialogue, alternate natural turns between the provided speakers. Each segment must include the matching speaker and voiceId.

Storytelling Rules

• Preserve the article's real meaning and order.
• Make the script feel like a clear story, not a slide readout.
• For one narrator: concise, warm, explanatory, and easy to listen to.
• For two speakers: make the second speaker ask or react naturally; do not make both speakers read the same article paragraph.
• Keep each shot's spoken text close to its target duration.
• Prefer Thai when language is Thai.
• Do not invent claims, numbers, sources, quotes, guarantees, or factual details not present in the article.
• Do not mention CSS, overlay, camera movement, reference images, video model, TTS provider, API, or implementation details.

Safety Rules

• No provider credentials, hidden metadata, tokens, URLs, or signed upload links.
• No code fences.
• No implementation instructions.
• No unsupported medical, financial, legal, safety, or performance claims.
• If the article content is too thin, return a short segment and add a warning instead of fabricating.

Duration Guidance

• 5 seconds: one compact sentence.
• 10 seconds: one or two short sentences.
• 20 seconds: two to four natural spoken lines.
• Longer projects should distribute ideas across shots instead of making one long monologue.
