ReadSpeaker’s speechEngine for Unity is a text-to-speech (TTS) plugin that empowers game developers to embed AI-driven voices directly within their projects, enhancing accessibility and offering new possibilities for on-device dynamic audio.
Game developers often face challenges when incorporating synthetic speech due to technical barriers such as file management, latency, and the need to work with external TTS systems.
These limitations made it difficult to use TTS for real-time audio in games, complicating the development process and impeding player accessibility.
Developers needed an in-engine, latency-free TTS solution that could seamlessly integrate into their existing workflows, allowing for dynamic voice features like NPC dialogue, UI narration, and in-game chat.
ReadSpeaker’s speechEngine for Unity provides developers with a direct, efficient way to integrate synthetic speech in real-time, eliminating the need for external file management.
The plugin, compatible with Unity and Unreal Engine, offered a library of lifelike voices powered by deep neural networks (DNN), with customizable pronunciation, pacing, and tone controls.
The plugin’s applications span various areas, including UI narration for visually impaired players, in-game chat narration, prototyping dialogue during development, and lifelike speech for AI-driven NPCs, all rendered instantly within Unity.
This TTS plugin also enhances game accessibility by meeting CVAA requirements for narrating in-game text in multiplayer experiences, making it an ideal tool for studios prioritizing inclusivity.
ReadSpeaker’s speechEngine for Unity has provided developers with flexible, accessible, and high-quality voice synthesis capabilities:
“The plugin allows us to experiment without the need to lock our decisions, which is a very powerful tool to have the privilege to use.”
— Conor Bradley, Director at Soft Leaf Studios
