Deploy Agentforce Voice in Japanese in Your Production Environment

Deploy Agentforce Voice in Japanese, now generally available for production environments. Set Japanese as your agent's default language and use a verified Japanese voice to serve customers on live calls.

Japanese moves from beta to generally available.

Note Japanese voice settings in the Agentforce Builder canvas appear dimmed and can't be edited. This canvas limitation doesn't affect Japanese voice functionality at runtime. Use Agent Script to configure supported Japanese voice settings. Keyword Boosting terms entered while another language is selected also apply when the agent runs in Japanese.

The Speed, Similarity, and Stability controls aren't yet available for Japanese. Support for these controls is planned for a future release.

Where: This change applies to Lightning Experience in Enterprise, Unlimited, and Developer editions.

When: This change is available starting August 7, 2026.

How: Set Japanese as the agent's default language and pair the agent with a verified Japanese voice. Use Agent Script to configure the applicable voice settings. For complete steps, see Create a Voice-Enabled Agent.

This example Agent Script sets Japanese as the default language and configures a Japanese voice with Keyword Boosting terms. The voice_id value is for the Azawa persona: a male, natural voice with a composed and conversational Japanese delivery.
