[FEATURE] Voice assistant initially responds with a male voice; should switch to female voice as per configuration in Ten Agent

Description

When interacting with the voice assistant, the initial response is delivered in a male voice even though the configuration has been updated to use a female voice in the Ten Agent settings. The voice should immediately reflect the selected preference to ensure a consistent user experience.

Severity

Minor

Additional Information

Steps to Reproduce
Start the voice assistant.

1. Ask the first question — the response comes from a male voice.
2. Change the voice configuration in the Ten Agent to female.
3. Continue the conversation — the voice should switch immediately but doesn't.

Expected Behavior
Once the voice configuration is changed to female in the Ten Agent, all subsequent responses from the voice assistant should be in a female voice.

Actual Behavior
The voice assistant continues to respond in a male voice initially, and the switch to the configured female voice happens only after the first response or with a delay.

Start by reproducing the issue in the voice assistant through the Ten Agent settings: select a female voice, ask an initial question, and observe subsequent responses. Trace where the selected voice is applied before the first response and verify that all later responses immediately use the configured voice.
