3 Key Points

What happened
NTT TechnoCross launched an 'AI Voice Interpreter' option for its on-premises IP-PBX 'Crossway', handling Japanese, Vietnamese and English two-way interpretation with all speech processing done on-site, no external cloud.
Why it matters
Because voice data never leaves the facility, the option can be used in environments with strict confidentiality requirements, and existing Crossway phones, smartphones and speaker devices work as-is, reducing new hardware and management costs.

WHO IT HITSFactory, logistics, nursing-care and municipal-counter managers who supervise multilingual staff can deploy real-time interpretation without sending sensitive conversations to the cloud, while their foreign employees can report problems in their native language over familiar desk phones.
