Questions about TTS in game development?
We’re just a click away on Discord.
“We wanted a solution that could feel extremely responsive to user input without putting a heavy load on the CPU… Using ReadSpeaker’s solutions, we were able to synthesize TTS audio for 24 unique languages… [and] we had a markup language included that allowed us to adjust the pronunciation of certain words.”
“Integrating ReadSpeaker’s text-to-speech plugin took around 20 minutes and automatically gave a voice to each line of dialogue created within my character engine. There was a lot of nuancing to get the right tone, timing, and intonation, but essentially Acolyte went from a text-only experience to a fully voiced game with almost infinite lines [of voice-over] in less than half an hour.”
“Within about five minutes, it just worked. It was Skyrim, it just worked!”
Enjoy near-zero speech latency: ReadSpeaker’s CPU-based TTS engine delivers lightning-fast, always-available on-device lifelike speech wherever it’s needed, never breaking immersion or taking players out of the action. With or without connectivity.
Our plugin can famously be installed within minutes from just two lines of code.
Build accessibility features once then deploy TTS across all major gaming platforms (PC, mobile, consoles, and server):

ReadSpeaker’s natural and expressive TTS voices add valuable flexibility to game audio, enabling dynamic updates to dialogue long after actors have left the recording studio.
ReadSpeaker prioritizes ethical practices by collaborating directly with voice actors in a way that allows for dynamic expansion of a script from the same initial recordings. This ensures that voice actors are protected and that the creative integrity of their performances is preserved, whilst avoiding costly additional or re-recordings.

Yes! It’s true that most TTS solutions for video games are cloud-based, streaming tools, so they require an internet connection. But ReadSpeaker’s gaming plugins are different.
Our TTS engine runs on the gamer’s device, which eliminates the need for an internet connection. It also speeds up performance considerably.
Of course, we also offer more conventional streaming TTS through an API, if that’s what you’re looking for. Just choose the speechEngine SDK if so.
The answer depends on a number of factors, most notably the TTS voices you choose. Our top-quality AI voices (built on neural Hidden Markov Models, HMMs) only occupy between 13 and 16 MB per voice.
Our DNN-based AI voices might take up to 32 MB per voice, however. We also use a technology called DNN Micro, which can run as low as 4 MB per voice.
This question also depends on the CPU your gamer’s device has available. Neural Standard voices need 1 GHz or higher on a 64-bit processor, while Neural Lite voices run from 800 MHz.
If the CPU only offers 400 MHz, it might be limited to our Unit Selection Synthesis (USS) voices, which take between 80 and 600 MB per voice. They still deliver high quality, just not as high as our best AI voices.
To sum it all up, the TTS footprint is based on the TTS voice, and can run anywhere from 4 to 600 MB per voice.
We’ll work with you to find the technology that offers the best combination of quality and footprint for your unique project.
Our gaming plugins provide TTS in more than 40 languages and dialects. See which in the section "Localize your game in over 40 languages" higher up on this page.
Just click on any language to sample a voice in that language and click on the voice name to choose another voice to sample.

ReadSpeaker can build an ethical custom voice (aka ethical voice clone) for you, but we are a B2B company, and we do not offer DIY or self-service voice cloning.
Ethical AI-powered Voice solutions are our core priority. We simply can’t guarantee ethical usage if we make our technology available to all.
When we create TTS voices, we set up fair contractual agreements across the TTS chain, from the voice actors to the user. That’s the only way to avoid exploitation or unauthorized use of voice data, and we don’t see a way to offer voice cloning ethically on the self-service model.

The audio format breaks down accessibility barriers for lots of gamers, including players with blindness, low vision, dyslexia, attention deficits, cognitive disabilities, or a simple preference for auditory experience over reading.
The key to gaming accessibility is to offer each player lots of choice. Let them decide how they interact with your experience.
Every gamer brings a unique combination of needs, capabilities, and predispositions to your game. You want to meet each player where they are, and you can only do that with lots of options.
Some gamers may require audible UI narration to play, while others may do fine with text resizing or no accommodations at all.
But if you don’t offer TTS accessibility tools, you run the risk of leaving people behind, and shrinking your target audience considerably.
GenAI speech and neural text to speech both use advances in artificial intelligence. GenAI TTS generates voices from scratch and often needs heavy online processing, while ReadSpeaker’s neural TTS engines are based on deep learning models trained on high-quality recordings and are deterministic.
This ensures natural, expressive speech optimized for gaming, with a focus on performance and seamless integration. Crucially, our voices run offline directly within your game engine, giving you greater control and reducing latency to near zero. Essentially, ReadSpeaker’s TTS leverages AI to deliver high-quality voice content with greater efficiency and flexibility for game developers.
Yes, you can use ReadSpeaker’s voice content authoring tools (AI Voice Generator) to pre-generate audio with our AI voices for your game, giving you offline prompts. However, for maximum flexibility and dynamic in-game runtime speech generation, we recommend our dedicated offline plugin for game engines like Unity and Unreal Engine.
Absolutely! With ReadSpeaker’s AI-powered text-to-speech voices for gaming, you can easily update elements of your game’s dialogue without needing to re-record. This saves you time and resources while maintaining consistency and quality in your artificial intelligence-powered text-to-speech voiceover.
Yes, absolutely! Our AI voice engine can speech enable any text you provide, regardless of whether it’s generated by AI (AI text) or written by humans, making it perfect for bringing your indie game’s dialogue to life.
It’s easy to bring your NPCs to life with ReadSpeaker! Simply integrate our AI-powered text-to-speech gaming plugin directly into your game engine (like Unity or Unreal Engine) and you’ll be able to give every character a dynamic voice at runtime.
ReadSpeaker does not offer a self-service voice clone feature. This is because we prioritize ethical AI technology development and responsible use of voice data in a B2B context, which includes ensuring fair agreements with voice actors and preventing misuse. We’re happy to discuss other ways our diverse range of AI voices can help bring your school project to life!
