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.”
“ReadSpeaker’s SDK for Nintendo Switch is a development tool for embedding a Deep Neural Network (DNN) text-to-speech engine into Nintendo Switch games. […] By using this SDK, Nintendo Switch game developers can easily implement a Voice User Interface (VUI) that performs text-to-speech in real time, which can be used for interactive voice dialogs and in-game announcements.”
“Innovative DNN speech synthesis and custom voice developed ReadSpeaker are integrated in Konami Amusement Co., Ltd.’s latest arcade game, “QuizKnock STADIUM.”
ReadSpeaker’s cutting-edge AI voice synthesis utilizes deep learning and machine learning to create highly expressive and natural-sounding voices. […] ReadSpeaker’s technology allows for a wide range of emotions, including happiness, anger, and sadness, to be conveyed in a human-like manner. This integration marks a significant step forward in enhancing the immersive gaming experience for “QuizKnock STADIUM” players.”
“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!”
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' 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. If it supports up to 800 MHz or higher, it can run our DNN, HMM, and DNN Micro voices.
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 35 languages and dialects, including:
Listen to voice samples of these languages (and more) here.

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.
Although Gen AI speech and text-to-speech voices have advancements in the application of artificial intelligence as a common denominator, the latter typically involves generating voices from scratch, often requiring significant online processing. ReadSpeaker's AI-powered TTS voices, on the other hand, are built on deep learning models trained on high-quality recordings.
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.
