Our Technology


Leading proprietary ASR/MT technologies

AppTek ASR/MT solutions were developed based on years of R&D experience, innovative technology, intellectual property and system testing. These end-to-end solutions seamlessly integrate across multiple solid technologies to create a robust and scalable platform. We specialize in rapid and flexible efficient language / domain / dialect development and adaption. Our experience brings a large amount of of well-prepared in-house/proprietary text/acoustic data.

Automatic Speech Recognition (ASR)
Converting voice into manageable data
Equipped with Deep Neural Network and GPU technologies. High-quality, fast, noise/dialect/domain adaptive.
Machine Translation
Highly accurate, patent-pending
Deep Neural Network (DNN) and SMT.

Individually, and together, both our ASR and MT technologies are trainable, scalable and adaptable machine-learning engines developed to meet virtually any challenge.  We can develop customized models trained specifically for your use case.
