[Zoom Contact Center] Call Recording Transcripts Outputting in English for Japanese Calls

Hello,

We are currently using Zoom Contact Center and encountering an issue with our call recording transcripts. We would greatly appreciate it if anyone could provide insights on the correct settings or a potential workaround.

■ Issue Description

Even though the calls are conducted entirely in Japanese, the post-call recording transcripts (retrieved via the API’s transcript_url / WEBVTT, as well as the recording transcripts in “Customer Experience Analytics”) are being outputted in English. The system seems to be phonetically spelling out Japanese pronunciations into English words.

  • Examples: “〜ます” (masu) → “masse” / “ka masse”, “お願い” (onegai) → “Oniga”, Customer speech → “Either of us?”, “Hi”, etc.

Upon checking our last 25 recordings, only one was correctly transcribed in Japanese.

■ Key Clue (Comparison Within the Same Call)

When analyzing the exact same call, there is a stark contrast between the two transcription features:

  • Live Transcript (Real-time during the call): Accurate Japanese (even the operator’s self-introduction is recorded perfectly).

  • Recording Transcript (Post-call via transcript_url): Corrupted into English, making the content completely unreadable.

(Example: Engagement ID - B_GYxn6RGa8g1u8v1VjDA. We have attached the raw VTT file of the recording transcript for reference.)

■ Settings Already Checked

  • Contact Center Management > Preferences > Voice Engagement:

    • “Allow call recording transcription” = Enabled
  • Same section > Live Transcription and Auto-Transcription > Language:

    • Set to Japanese
  • Account Settings > Recording and Transcription:

    • We could not find any specific setting to define the language for Contact Center recording transcripts.
  • Data Storage Region: Japan

■ Questions

  1. Where is the setting to lock/force the post-call recording transcript language to Japanese? If the system is automatically detecting the language incorrectly and defaulting to English, is there a way to prioritize Japanese?

  2. If the above is not possible, is there a way to retrieve the accurate Live Transcript via the API (Server-to-Server OAuth)? Currently, the transcript-related endpoints under the Engagement API return an empty response, and the recording object only provides the corrupted post-call recording transcript.

  3. If this is a known limitation or current specification, could you let us know if there are any plans for improvement, along with a recommended workaround?

■ Environment

  • Feature Used: Zoom Contact Center (Voice)

Thank you for your time and assistance. We look forward to hearing from you.
