NPC dialogue and barks
Give each character a saved template and use expression tags for urgency, fear, confidence, or surprise.
For game creators
Use TextToSpeechSkills for prototypes, indie games, internal playtests, and live content systems that need expressive speech. Save character voices as templates, add emotion with inline tags, and generate audio through the UI, API, or your LLM app.
TextToSpeechSkills helps game creators generate voice lines for NPC dialogue, tutorials, mission updates, prototype scripts, and dynamic character barks. Each character can use a reusable voice template, while expression tags add emotion and delivery notes such as urgency, fear, confidence, or surprise. Non-technical creators can connect an LLM app through MCP, ask it to draft lines, validate tags, check credit use, and create speech jobs. Developers can later move the same workflow into the game backend or tooling without changing the content model.
Easy LLM setup
Ask an LLM to write NPC lines, then let the installed MCP tool validate tags, select a character template, check credit use, and create the audio job for you.

Turn onboarding steps, quest text, and live event updates into consistent narration without recording sessions.
Let an LLM generate draft lines and speech assets from one workflow, with account limits keeping experiments controlled.
Game creators, indie teams, modders, and interactive fiction builders usually need a repeatable path for writing, review, generation, billing, and reuse. The most important jobs here are npc dialogue and barks, tutorials and mission updates, prototype faster with agents. Those are the moments where voice becomes part of real work instead of a one-off export.
Start with readable text, add expression tags when tone matters, choose an approved voice template, and create a speech job through the UI, API, or MCP. The same pattern works for text-to-speech for games, NPC voice generator, game narration TTS, which makes it easier for humans and LLM apps to share one process without exposing internal routing or credentials.
Decide which templates are approved, which expression tags are allowed, who can create workspace keys, and which usage limits are acceptable. Those choices keep automated voice generation useful without letting it sprawl from the first paid Test plan through Pro, Scale, and Business usage.
Common questions
These are the practical details that matter before a team adds speech generation to a real workflow.
Game creators, indie teams, modders, and interactive fiction builders should use this page when they want generated speech that is easy to review, consistent across prompts, and simple to connect to LLM tools. The core workflow combines expression tags, voice templates, credit previews, and job-based generation.
Ask an LLM to write NPC lines, then let the installed MCP tool validate tags, select a character template, check credit use, and create the audio job for you. The setup guide keeps the first path short while still giving developers a clean API when the workflow moves into a product backend.
Every paid plan uses credits. Teams can add credit packs when needed, and workspaces on Pro and higher add central billing for $2 per user per month.
