・"alt STT" speech recognition API

alt STT is the API for our high-precision speech recognition engines, including AI GIJIROKU, an AI automatic minutes tool, as well as industry-specific engines designed to recognize technical terms and phrases in a range of fields. We also plan to make it possible to customize our speech recognition engines.


・"alt Translator" machine translation API 

This is the API for the "AI GIJIROKU" translation engine, which can be used to localize services and build automatic interpretation applications in combination with speech recognition.


You can use our speech recognition and machine translation technologies immediately through "alt developer". If you are already a BORDERLESS VISION K.K. customer and have an alt ID, please log in. Customers who do not yet have an alt ID can use the service immediately by clicking "Sign Up."


In the near future, we will release "alt DIGEST", an automatic summarization API that outputs a summary of the input text based on a nuanced understanding of the context using AI. Also coming soon is "alt Speaker Identifier", a speech synthesis API that utilizes "AI GIJIROKU"'s speaker identification function, which boasts 98.6% accuracy. The API based on various P.A.I. technologies will also be available for use.


Through "alt developer", we will support our customers in creating a better user experience while responding to a wide range of needs, such as software and service development and consulting for DX. In addition, we will contribute to the realization of a more affluent society through various foundational technologies centered on P.A.I. and its integrations.



■ What is P.A.I. (Personal Artificial Intelligence)?

P.A.I. (Personal Artificial Intelligence) is an original research and development project by alt. P.A.I. digitizes human intentions and judgments as reproducible clones and places them in the cloud, with the goal of replacing all digital tasks with those clones.
