Different Workflows for Games and Animation

For Game Developers

Goal: Voice 500-5,000+ NPC lines + main characters + cutscenes
Approach: Economy tier for bulk NPCs; Studio+ for protagonists
Timeline: 2-4 hours generation + 1-2 days QA vs. 4-6 weeks with voice actors
Integration: Export MP3 → Unity / Unreal / Godot dialogue system
Cost example: 500 NPCs (Economy) + 200 protagonist lines (Studio+) = ~$25-30/mo

For Animation Studios

Goal: Consistent character voices across episodes / seasons
Approach: Studio+ for all speaking characters — emotional consistency
Timeline: Hours per episode vs. $1,000-5,000 with voice actors
Integration: Export WAV → animation software timeline sync
Cost example: 10-episode series (1,500 total lines) = ~$50/mo

Directing Character Performance with Emotion Tags

Emotion tags replace traditional voice direction notes — available in Studio+ tier. Place before any line to direct delivery. Full emotion tag guide →

Game Dialogue Examples

Battle / Combat

[excited] "Charge! Don't let them regroup!"

[angry] "You dare challenge me?!"

[serious] Ready your weapons. They're coming.

Story / Character Scenes

[sad] "I never thought it would end this way..."

[calm] "Take a deep breath. We'll figure this out."

[excited] "You actually saved the kingdom!"

Boss Encounters

[serious] [whisper] "So... you've finally come."

[laugh] "This will be... entertaining."

[angry] "Enough games. You die here."

NPC / Tutorial

[calm] "Welcome to my shop. Browse my wares."

[serious] "You're not allowed past this point."

[excited] "Thank you for saving our village!"

Animation Dialogue Examples

Dramatic Scenes

[serious] "This changes everything we thought we knew."

[sad] "They're gone... and it's my fault."

[whisper] "Don't tell anyone... but I think I love them."

Action / Comedy

[excited] "Let's do this! For victory!"

[angry] "You'll pay for what you've done!"

[laugh] "That's the stupidest thing I've ever heard!" [laugh]

Pro tips: Use 1-2 tags per character turn. Combine tags: [excited] [serious] for intensity + focus. Test the same line with multiple tags and pick the best delivery.

Step-by-Step Workflow

Game Development Workflow

Write dialogue script in spreadsheet (character, line, emotion note)

Assign voice tier per character — Economy for NPCs, Studio+ for protagonists

Enter text in SG.ai, select voice per character

Add emotion tags for Studio+ lines

Generate audio in 500-char batches

QA — check pronunciation and emotional delivery

Export as individual MP3 files per line

Import into game engine (Unity / Unreal / Godot)

Cost example: 500 NPC lines (Economy) + 200 protagonist lines (Studio+) = ~$25-30/mo vs. $5,000-10,000 with voice actors.

Animation Workflow

Script episode (150-200 lines, character-labeled)

Create multi-voice project, assign character voices

Add emotion tags for dramatic delivery

Generate episode in 500-char sections

Export WAV files per scene

Sync audio to animation timeline (Blender / Toon Boom)

Generate multilingual dub versions separately

Cost example: 10-episode series, 1,500 total lines with 8 characters = ~$50/mo vs. $10,000-30,000 with voice actors.

Exporting to Game Engines

Use MP3 192 kbps for games, WAV for animation. Name files descriptively: character_emotion_line-number.mp3

Unity

MP3

AudioClip → AudioSource component → trigger on dialogue event

Fastest setup, no conversion needed

Unreal Engine

WAV preferred

Sound Wave asset → play via dialogue system

Use WAV; convert MP3 with Audacity first

Godot

MP3 / OGG / WAV

AudioStreamPlayer node → trigger on event

Open source, all formats natively supported

RPG Maker / GameMaker

MP3

Asset library drag-and-drop → dialogue event

Simplest integration, works out-of-the-box

Animation lipsync: SG.ai exports standard audio files. Use Rhubarb Lip Sync (free, open source) to generate phoneme timing data from your exported audio for frame-accurate lipsync in Blender or Toon Boom.
