Kotoba Technologies has announced a partnership with U.S.-based Cresta. Kotoba's speech recognition and speech synthesis models, including Japanese-language models, will be integrated into Cresta's Voice AI for contact centers. The rollout is planned to begin in stages from 2026.
Kotoba Technologies announced on 11 November that it will partner with U.S.-based Cresta, which provides an AI platform for customer experience. Kotoba's speech recognition and speech synthesis models will be provided for integration into Cresta's Voice AI agents for contact centers, supporting the automation of telephone interactions.
Under the partnership, Kotoba will provide its in-house speech recognition and speech synthesis technologies, while Cresta will integrate them into its AI platform. The technologies will be used for agent assistance, support for live operators and conversation analysis by making use of information transcribed through real-time speech recognition. Speech synthesis will read responses aloud in natural-sounding voices, with the aim of making conversations more fluid.
Supported languages are planned to include Japanese, Korean, Chinese and English, with the rollout scheduled to begin in stages from 2026. The services are expected to be offered to Cresta's enterprise customers.
Kotoba offers its Koto model, which is strong in East Asian languages including Japanese. Koto supports ultra-low-latency processing and may support speech-to-speech translation in addition to speech recognition and speech synthesis. The company aims to expand the supported languages and use cases.
