ReadSpeaker has unveiled a new plugin to help balance immersion and accessibility without sacrificing workloads for video game developers. 

This plugin is called speechEngine. It aims to eliminate the hurdles faced with traditional TTS, which requires recording audio or creating static audio files.  

Accessibility as a Competitive Advantage 

For game studios, enterprise developers, and publishers, accessibility is no longer optional. It is moving from an afterthought or compliance checkbox to a differentiator. 

In an industry where engagement and reach are critical, making XR content accessible to a wider audience that includes people with visual impairments, cognitive differences, or language barriers can directly impact a video game’s success.  

However, accessibility options are often added toward the end of development once the core gameplay features have been established. This is where issues that would affect inclusivity are identified and addressed, which could require significant rework and additional costs to implement specific accessibility aids. 

Traditional voiceovers can be time-consuming and costly. ReadSpeaker’s real-time TTS solution seeks to avoid this by aiding developers in creating and integrating real-time voice synthesis. 

Most importantly, this could allow teams to deliver dynamic, voice-powered interactions without inflating production time or costs. It could even grant them more time to produce high-value content. 

Streamlining Workflows with Ethical Voice AI 

Beyond productivity gains, ReadSpeaker’s use of voice AI for accessibility stands out for its ethical approach.  

We’re in a time where unauthorized voice cloning and AI-generated media content are rising concerns, but ReadSpeaker prioritizes transparency and consent with their plugin.  

speechEngine’s voice library is built in direct collaboration with real voice actors who have agreed to ReadSpeaker’s usage terms, which ensures their voices are licensed and ethically used.  

This approach aligns with expectations of responsible AI use. This means developers can scale content faster without relying on manual voiceover work, all while explicitly avoiding unauthorized voice cloning. 

Powering Scalable Accessibility in RT3D 

ReadSpeaker’s TTS capabilities could empower accessible XR experiences across non-entertainment industries. These could include: 

  • Healthcare: TTS may help create accessible patient simulations and training modules. 
  • Retail: Virtual showrooms may benefit from multilingual voiceovers or audio descriptions to dynamically guide users through product features. 
  • Automotive/Architecture: Voice-enhanced RT3D experiences could support safer and more intuitive user navigation.  

Through diminishing the accessibility barriers by implementing voice AI in RT3D environments, real-time TTS could help teams easily build inclusive solutions regardless of their budget or technical expertise. 

Setting Standards for Responsible AI-Use for XR 

Generative voice AI will undoubtedly become more prevalent in gaming and other XR experiences, and the ethical implications of using it cannot be overlooked.  

ReadSpeaker’s stance on responsible AI use, emphasizing transparency in contracts and consent from voice actors, could set new ethical standards across the XR and AI development landscape.  

Taking ethical AI seriously can help ensure inclusivity and transparency for both users and stakeholders, remaining front and center.
