Rakuten AIris

What it is

Rakuten Institute of Technology has long-running speech-recognition research and ships internal ASR across Rakuten's e-commerce, banking, and telecom subsidiaries. Outside the group, the technology is accessed via partner agreements rather than developer signup. Useful reference point for any Japanese enterprise considering an in-Rakuten transcription rollout. Best fit when the buyer is japanese-language transcription inside the rakuten ecosystem (commerce, fintech, telecom). The honest caveat: not a self-serve developer product; engagement is via partner channels. Procurement is via direct sales rather than a developer signup, so plan for a discovery call and a written proposal before the first transcript runs.
