      Bridging the Gap: Edge vs Desktop

      On Airoha devices, our cutting-edge model was able to achieve 75% of the performance of the Desktop model, with a 25x reduction in size.


      Continuous Improvement

      Driven by Feedback and Innovation

      Our success lies in the continuous refinement of our algorithms, fueled by the feedback from our growing user base of PC app users. Our proprietary speech dataset features more than 100,000 unique speakers across 99 languages, which helps us refine and improve our algorithms. We also value our clients’ privacy and do not use their data for training. Instead, we rely on public datasets with permissive licenses and conduct our own data collection with consent.
