Kotoba just announced an additional $10M round with @KindredVentures, @SalesforceVC and @Sony_Innov_Fund. This is just the beginning of our push on voice AI for East Asia 🔥🔥 Our models are great for: 1. traditional cascaded approach with STT + LLM + TTS for agent use cases 2. end-to-end full-duplex with our speech-to-speech model: our simultaneous translation shows sub-2-second latency — voice agents coming soon! Try out our speech models on our SDK/API and the Kotoba app! Read more: businesswire.com/news/home/2…

Salesforce Ventures is proud to invest in @kotoba_tech 🚀 Voice is becoming the primary interface of AI. And for hundreds of millions of Japanese, Korean, and Chinese speakers, the gap between what global platforms offer and what they need has never been wider. Kotoba is built to close that gap. Their model, Koto, delivers real-time speech translation and voice interfaces for East Asian languages — at broadcast-quality accuracy, running on-device, and built to slot into the agentic systems that are reshaping how people interact with software. Founders Noriyuki Kojima and Jungo Kasai are two of Japan's most decorated NLP researchers — both Best Paper Award winners, both Masason Foundation Fellows. Proud to back them and the entire Kotoba team 🤝 🔗 On our blog, Ken Asada and Sho Yamanaka, CPA shared more about our investment in Kotoba: salesforceventures.com/persp…

Thrilled to welcome @kotoba_tech to the @Sony_Innov_Fund family as our latest #AI investment, alongside our good friends at @KindredVentures and @SalesforceVC! ㊗️ Kotoba is is tackling one of the hardest frontiers in #AI: real-time speech-to-speech #translation & #interpretation that feel natural and seamless. Thanks to its state-of-the-art Koto foundational AI #model, Kotoba unlocks the next wave of #voice-based #UX and #interfaces, by allowing them to be natively #multilingual. ✨ Leveraging on its roots spanning both #Japan and #US, Kotoba achieves outstanding low-latency and accuracy from/to #Japanese and other #Asian languages, where grammar, word order, context as well as sentence construction can differ fundamentally from English and other Western languages. 🇺🇸🇯🇵 With multiple embedding & integration of Koto across enterprise and consumer applications well underway, alongside the recent launch of Kotoba's API & SDK, genuinely look forward to working closely with @noriyuki_kojima, @jungokasai and the broader Kotoba team as they scale their voice AI platform across both #Cloud as well as #Edge deployments! 🚀 gamesbeat.com/kotoba-technol…
