Accessible Game Development with ReadSpeaker’s Text-to-Speech Plugins for Gaming

Why Accessibility Matters in Game Development

Today’s players expect more from their games—including inclusion. As accessibility becomes a standard across the industry, tools that help developers meet diverse player needs without adding heavy dev load are in high demand.

This is where ReadSpeaker’s text-to-speech plugin for gaming plays a unique role. From AAA studios to solo indie creators, it empowers teams to create accessible games that are inclusive, flexible, and immersive—without compromising performance.

From Static Audio to Real-Time TTS

Traditionally, implementing TTS in games meant generating speech as static audio files—cumbersome, slow, and limiting. ReadSpeaker’s speechEngine plugin for gaming eliminates that roadblock with real-time, on-device voice synthesis.

Key Benefits

• Dynamic speech generation at runtime
• Narration for menus, UI, and gameplay
• Simplified voice integration early in development
• Lightweight deployment with no bloated audio libraries

One Plugin, Every Platform

Build Once, Deploy Anywhere

ReadSpeaker is built with true cross-platform support in mind. Its TTS plugin runs natively on:

• Consoles: PS4®, PS5®, Xbox Series X™, Nintendo Switch™
• PC: Windows and Linux
• Mobile: Android and iOS

Whether you’re targeting one platform or all of them, speechEngine ensures your TTS functionality remains consistent across the board.

Built-In Support for Unity, Unreal—and Soon, Wwise

ReadSpeaker offers deep integrations with leading game engines to minimize ramp-up time and maximize flexibility.

Unity & Unreal

• Pre-built components and code-friendly setup
• Blueprint nodes in Unreal
• Just a few lines of C# in Unity
• Fully customisable or plug-and-play simplicity

“There are only a few steps: configure the component, initialise the plugin, and send text to be converted to speech,” explains Pontus Melin, Product Manager Gaming Solutions at ReadSpeaker.

Wwise (Coming Soon)

• Use speechEngine as a runtime audio source
• Process TTS output with real-time audio effects
• Export voice models into SoundBanks
• Fully integrated via Wwise SDK pipeline

Accessibility First: TTS for Inclusive Game Design

Accessibility isn’t just a feature—it’s a design philosophy. With ReadSpeaker, adding text-to-speech to your game is easy, flexible, and impactful.

Example Use Cases

• Narrate UI for players with visual impairments
• Auto-generate spoken tutorials or hints
• Prototype dialogue with real voice delivery
• Adaptive voice-over for interactive storytelling

By linking a “Speaker” component to a UI element, you can have it auto-speak the displayed text—no manual audio syncing needed.

“Developers used to pre-generate TTS audio. We enable them to do it dynamically with just a few lines of code,” says Pontus.

Lightweight Performance, Heavyweight Sound

ReadSpeaker’s neural TTS voices are not only realistic—they’re also optimised for runtime efficiency.

Performance Highlights

• Runs on a single CPU thread
• Easily scaled down for mobile hardware
• Minimal memory footprint (10–20 MB)
• Configurable voice quality per platform

Built on Ethical AI Voice Technology

With concerns around voice cloning and consent in the AI space, ReadSpeaker takes an ethical approach. Our neural voices are developed with:

• Direct collaboration with voice actors
• Transparent contracts and usage terms
• No unauthorised voice cloning

This ensures respectful treatment of talent while giving developers safe, professional-grade voices to work with.
