Adapt4Me advances inclusion through digital tools that adapt to the user, not the other way around. Our goal is that everyone is understood despite impairment in speech. We also work on diagnostic tools for speech therapists.
Personalized Speech Recognition.
We believe that everyone deserves to be understood. While speech recognition has become widely available, a large community is still being left behind: people with speech disabilities. We believe that individuals should not have to adapt to technology. Instead, technology must adapt to the individual. That is why we are working under high-pressure to make speech recognition personalized and accessible to everyone.
How it work
It starts by listening to you. During onboarding, the app builds a personal speech profile based on your pronunciation and style. As you use it, simple corrections help the system learn continuously, making speech recognition more natural and reliable over time.
Who it’s for
It is made for people whose voices are not well understood by standard speech technology. It also supports families, caregivers, and social environments by enabling clearer communication and reducing everyday misunderstandings.
Why it matters
It removes communication barriers by adapting to the individual, not the average. It supports independence, builds confidence, and helps people reconnect with the joy of being understood in daily conversations.

Support tool for speech therapist
A second focus is supporting speech therapists in diagnosis and treatment. Adapt4Me includes an algorithm for automated phoneme analysis, designed for use in clinical and educational settings. This tool does not replace professional expertise; it complements it with objective, data-driven insights for assessment, monitoring, and personalized intervention. The result is more precise, efficient, and accessible speech therapy.
The Research
Semantic re-chaining
A method to personalize speech recognition with minimal data by generating sentence variations from a small set of words. This expands training data and improves recognition, even in low-data scenarios.
Variational LoRA
A lightweight adaptation technique that enables robust personalization from limited speech samples. It improves model stability and handling of uncertainty, with validated results in both English and German. More→
Phoneme uncertainty
An approach that identifies difficult speech sounds based on model uncertainty and prioritizes them during training. This leads to improved accuracy and aligns closely with expert speech therapy assessments.

Be Part of Our Vision
We believe that every voice deserves to be understood. Our goal is a world in which communication is accessible, personal, and inclusive, regardless of how a voice sounds.
Adapt4Me is currently under development. To further develop the tool in a targeted way and adapt it to real needs, we are seeking exchange with people and institutions interested in inclusive communication.
If you have questions, are interested in the project, like the idea, would like to support us, or are considering funding or a donation, we would be pleased to hear from you.
Our Partners
For questions related to speech and speech therapy, we work closely with Samra Hamzic, the Head of Research at the Hochschule für Logopädie Ostschweiz.
We recently received funding for our project from Stiftung Cerebral. We also work closely with Stiftung Cerebral to benefit from the expertise of its users.
