About "スピークバディー"
What is SpeakBuddy
SpeakBuddy is an app from appArray, Inc. focused on practicing English conversation with an AI character. You practice role-play conversations across 1,000+ scenes with an "AI buddy," and it also has a free-form "Free Talk" feature powered by generative AI. Its strength is letting you practice speaking — which can be nerve-racking in front of others — anytime and anywhere; it has surpassed 5 million downloads.
Rack up speaking volume without worrying about your partner
Improving at conversation takes volume, but a human partner can mean nerves and constraints on time and cost. SpeakBuddy's strength is that because your partner is an AI, you can speak freely, as much as you want. Role-play across business, daily-life and other scenes, practice freely with generative-AI Free Talk, and cover pronunciation and the four skills — all in one app.
