ZoomPhoneの日本語環境でカスタム辞書に登録した単語で文字起こしの精度を上げる方法を教えてください。

 Hi ​@横田 浩之,

To improve Zoom Phone transcription accuracy using AI Studio > Custom Dictionary in a Japanese environment, the main thing you can do is make sure the terms are added in the format Zoom’s custom dictionary expects (so the speech-to-text engine can reliably match them).

Practical tips that typically help:

• Add proper nouns you expect in calls (company/product names, people names, place names).
• Add acronyms/initialisms and common industry terms that are often misrecognized.
• If a term is commonly misheard, add the most likely spoken variant(s) as separate entries (for example, different ways users pronounce the same name).
• Keep entries short and specific (very long phrases tend to be less consistently recognized than key terms).

On your question: “Does it still only work properly in an English environment?” The public Zoom guidance for AI Studio Custom Dictionary explains how to create/manage dictionaries to improve transcription accuracy, but it does not clearly state which languages (including Japanese) are supported or whether it’s English-only. So I can’t confirm from Zoom’s published info whether Japanese is fully supported or limited.
