What it is
Speak is an AI English-speaking practice app backed by the OpenAI Startup Fund. The product runs conversational AI lessons that let learners practice English speaking with high-quality voice AI tutors. Speak transcribes learner speech, scores pronunciation, and adapts the lesson plan based on the learner's level. The product has grown into one of the largest paid consumer AI apps with strong revenue in South Korea, Japan, Taiwan, and increasingly the US Hispanic market. Speak raised a $20M Series B in 2024.
Watch out for: ESL focus; not a meeting bot.
