The model card for Foundry linked below lists "Multilingual support across 10+ languages" under "Key capabilities," yet the "Key model capabilities" section lists only nine languages: English, Spanish, French, German, Italian, Portuguese, Hindi, Japanese, and Chinese variants.

https://ai.azure.com/catalog/models/MAI-Voice-2

Additionally, the official blog post below states that 15 languages ​​are supported in MAI-Voice-2.

https://microsoft.ai/models/mai-voice-2/

Which information is correct?

I would particularly like to confirm the support status for Japanese mentioned above.

    The currently supported MAI-Voice-2 prebuilt voices include Japanese.

    The authoritative details in the available documentation are:

    • MAI-Voice-2 key features state multilingual support across 15 languages and 18 locales.
    • The currently published MAI-Voice-2 prebuilt voices table lists these locales/languages: German, English (Australia and United States), Spanish (Spain and Mexico), French, Hindi, Hungarian, Italian, Korean, Dutch, Portuguese (Brazil and Portugal), Romanian, Russian, Thai, Turkish, and Chinese (Simplified).
    • That published MAI-Voice-2 prebuilt voice table does not list a Japanese MAI-Voice-2 voice.
    • The Azure Speech language support page does list Japanese MAI-Voice-2-Flash voices: ja-JP-Haruto:MAI-Voice-2-Flash and ja-JP-Sakura:MAI-Voice-2-Flash.

    So the supported facts are:

    • 15 languages is correct for the MAI-Voice-2 feature summary.
    • Japanese is confirmed for MAI-Voice-2-Flash, not for the currently published MAI-Voice-2 prebuilt voices shown in the voice list.
    • For MAI-Voice-2 specifically, the currently published prebuilt voice list in the documentation does not confirm Japanese availability.
