    16歳で渡英、イギリスで物理学と経営学を学んできました。在学中に英国気象庁でデータ解析・可視化基盤開発に従事。帰国後新卒でソニー株式会社に入社、製品ソフトウェアの開発、技術標準化、R&Dなどを担当。2014年10月に独立・創業し、2016年2月にAI英会話アプリ「TerraTalk」をリリース。

  • Joyz株式会社で第二言語としての英語学習に関する自然言語処理系の研究者兼エンジニアをやっています。学生時代は典型的な理系のそれであり、数理科学や自然科学に関することを主に学習・研究してきました。

    千葉大学に在学中は、物性物理、特にカーボンナノチューブ等、カーボン系や有機半導体の電子状態に関する数値計算をスーパーコンピュータを用いて解析するということを研究していました。また、電子状態に関しては、数値計算だけでなく紫外光電子分光などを用いた計測も行っており、真空や実験機器の制御などもやっていました[1]。

What we do

Teaching a language is hard. Improving the state of language teaching is even harder, since educating and training teachers for the next generation can take years of effort and massive investment. Because of this, some countries – such as Japan – have been lagging behind for decades in terms of the average English proficiency attained in public education.

Our solution is TerraTalk: a voice-enabled chatbot with an automatic assessment engine.

TerraTalk’s conversation lessons are role-play based. For instance, the app can play the role of an immigration officer at an airport, with the user pretending to be a traveler. The dialog engine is actually quite dumb (simple flow / state machine) and no machine learning is involved. We are measuring ‘correctness’ of users’ utterances instead, then deciding whether or not to progress to the next step.

Public and private schools across Japan are now scrambling to adapt to the policy change. Any solution needs to be low-cost enough to accommodate every enrolled student. They also need to ensure that quality of teaching is maintained and as consistent as possible across the board. All of this seems unattainable with the existing class of human-based services, including Skype-based tutoring.

How we do

We are a nimble team, comprised of professionals from all over the world.
