Shohei Ohtani, born July 5, 1994, in Oshu, Iwate, Japan, is a professional baseball player recognized for his rare ability to excel as both a pitcher and hitter. Ohtani attended Hanamaki Higashi High School, where he demonstrated his talents and was noted for his 99 mph fastball. He entered Nippon Professional Baseball (NPB) with the Hokkaido Nippon-Ham Fighters in 2013, quickly making an impact with his dual-threat capabilities.

Early Career in Japan
Ohtani’s time in NPB was marked by significant achievements. In his rookie year, he recorded a 3.53 ERA and hit .238. By 2014, he had improved his pitching and batting, achieving a 2.61 ERA and hitting 10 home runs. His 2016 season was particularly outstanding; he posted a 10-4 record with a 1.86 ERA and hit 22 home runs with a .322 average, earning him the Pacific League MVP award.

Transition to MLB
Ohtani transitioned to Major League Baseball (MLB) in 2018, signing with the Los Angeles Angels. His rookie season was notable, despite an elbow injury that limited his pitching. He finished with a .285 batting average, 22 home runs, and a 3.31 ERA in 10 starts, earning the AL Rookie of the Year award. However, Tommy John surgery in 2018 and subsequent injuries in 2019 limited his pitching.

Historic 2021 Season

Recent Career and Impact

Ohtani’s impact on baseball is profound, as he challenges the traditional separation between pitchers and hitters. His success has inspired many and brought significant attention to the sport globally.

Personal and Cultural Impact
Beyond his on-field achievements, Ohtani has become a cultural icon. His humility, work ethic, and exceptional talent have made him a beloved figure in Japan and internationally. His influence extends beyond baseball, contributing to increased interest and viewership of the sport.

Honors and Awards

2 多肢選択式問題の作成およびAI音声変換
ChatGPT4oのAI音声読み上げ機能を利用した読み上げ結果は下記の通りである。

  1. 以下では、問題文ごとにAI音声が聞けるようにした。なおChatGPT4oのAI音声読み上げでは選択肢の間にポーズがなく聞き取りにくいが、音声ファイルの編集は手間がかかる作業であるためとりあえず下記ではそのままとした。
  2. SSMLを使えるAI音声合成サービスGoogle-To-Textを利用して、適当に選択肢の間でポーズを持たせたイギリス英語AI音声を参考のために付け加えた。こうした多肢選択式ヒアリング問題の読み上げに関しては、ChatGPT4oとGoogle-To-Textとの間での音声的優劣はないように思われる。Google-To-Textに与えたSSMLのテキストを本ページの最後に参考としてあげておく。
  3. 各問題に対して、関連イラストをChatGPT4oに作成させた。ただしデフォルトのChatGPT4oでは地図のイラストに見られるように各種の間違いがある。しかしここではとりあえずそのままの形とした。
  4. 投手に関しては同一のイラスト画像を左右反転させることで、右投げ投手と左投げ投手のイラストを作成できたが、打者に関してはうまくできなかった。また、ChatGPT4oに様々なプロンプト文で右打者のイラストを描かせようと何回も試みたが、常に右打者しか生成しない。そのため、ここではウィキペディアの中の打者に関する写真をサンプルとして打者のイラスト図を作成させた。
