“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.”
“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 serious game and simulation audio, enabling dynamic updates to dialogue without re-recording.
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 the creative integrity of their performances is preserved.

Text-to-speech (TTS) technology improves teh learner experience and results by making content more accessible, engaging, and inclusive. It supports learners with reading difficulties, visual impairments, or language barriers by converting on-screen text into lifelike audio narration.
This dual-mode delivery reinforces instruction, helping students retain information through both visual and auditory channels. TTS also reduces cognitive load by allowing learners to focus on decision-making rather than reading, which is especially valuable in fast-paced or immersive scenarios.
For instructional designers, integrating TTS speeds up development by eliminating the need for manual voiceovers—while delivering a consistent, high-quality learning experience across all devices.
Text-to-speech (TTS) technology brings several key benefits to serious games and simulators used in education. It ensures accessibility for learners with diverse needs by providing spoken versions of written content—essential for users with dyslexia, low vision, or limited reading proficiency.
TTS also enhances engagement by creating a more immersive audio-visual experience, which supports different learning styles and improves information retention.
In addition, it streamlines content updates, allowing developers to make rapid changes without re-recording audio.
For education teams building simulations for classrooms or self-paced learning, TTS helps create inclusive, scalable tools that deliver consistent instruction in any environment.
Text-to-speech (TTS) is a strong fit for any serious game or simulator where accessibility, immersion, or real-time adaptability matters. This includes educational games for K–12 and higher ed, language learning apps, VR-based training simulations, STEM labs, digital assessments, and scenario-based soft skills training.
TTS is especially useful in content that changes based on learner input—like branching dialogues or adaptive feedback loops—where manual voice recording would be too slow or expensive.
Text-to-speech (TTS) technology adds a critical layer of realism to serious games and simulations by delivering spoken dialogue and instructional cues in real time. Unlike static voiceovers, TTS can adapt to dynamic scenarios—responding instantly to user actions, personalized content, or branching narratives.
This creates a more natural, immersive experience, where learners hear instructions, feedback, or character dialogue that feels responsive and context-aware.
With today’s neural TTS voices, the speech is not only flexible but also remarkably lifelike, helping simulations feel more authentic and emotionally engaging without the time and cost of manual recording.
Text-to-speech (TTS) in serious games refers to technology that converts written text into spoken audio, enabling game content to be heard as well as seen.
In educational simulations and training games, TTS is used to narrate instructions, read dialogue, or provide real-time feedback. Unlike pre-recorded voiceovers, TTS can generate speech dynamically—adapting to different scenarios, user choices, or content updates.
This makes it a powerful tool for creating more accessible, inclusive, and responsive learning experiences across platforms and devices.
