NTT has expanded its involvement in the generative AI voice sector through both protective services and technological advancements. In late September 2026, NTT West’s VOICENCE Company, in partnership with legal experts, launched a ‘Voice Consultation Desk’. This initiative was designed to assist performers and agencies in addressing unauthorized AI-generated voice usage, following reports of significant economic losses due to unauthorized AI content.

By late October 2026, NTT announced further developments in conversational AI applications. These include the ‘Voicesta!’ service by NTT Data, which uses generative AI to monitor the lifestyle and emotions of elderly users, and a specialized AI for preschool children developed by NTT Docomo to encourage healthy habits. Additionally, NTT has developed a bidirectional voice AI capable of natural human-like interactions, such as handling interruptions, with response times significantly faster than existing commercial services.
