OpenAI-backed ‘Speak’ secures funding to improve language learning through conversational AI

AI-powered language learning apps are transforming how people achieve spoken fluency in new languages, with Speak emerging as a leading platform that emphasizes conversational practice over traditional memorization methods.

Speak has secured a new funding round led by Accel, with participation from existing investors OpenAI’s Startup Fund, Khosla Ventures, and Y Combinator. This follows their recent $20 million Series B extension at a $500 million valuation.

The company plans to use the funding to expand its language offerings to include Spanish and French, demonstrating the commercial potential of generative AI applications in language learning.
