Auto Refresh CAPTCHA When No Speech Is Detected.

Is your feature request related to a problem? Please describe.

Sometimes the CAPTCHA solver cannot detect any speech in the current CAPTCHA challenge. In these cases, the process stops and requires the user to manually click the CAPTCHA refresh button before trying again.

Describe the solution you'd like

If no speech is detected in the CAPTCHA, automatically click the CAPTCHA refresh button to load a new challenge. After the new CAPTCHA is loaded, the user can manually start the solver again, keeping the project's manual-start policy unchanged.

Describe alternatives you've considered

Continuing to retry the same CAPTCHA is often ineffective when no speech is present. Manually refreshing the CAPTCHA works but requires unnecessary user interaction.

Additional context

This feature would only refresh the CAPTCHA when no speech is detected. It would not automatically start the solver or bypass the project's requirement that the solver must always be started manually from the extension button.
