siri prefer silent responses but not always

There is no setting for what you want to do. You may submit feedback to Apple requesting such feature.

Feedback - iPhone - Apple

Instead of ticking “prefer silent responses” I would recommend using "Automatic" because...

Siri's ability to determine when to speak on iOS devices relies on a combination of on-device intelligence and sophisticated algorithms. This process involves several steps:

1. Contextual Understanding: Siri analyzes the context of the conversation or situation. It considers factors like the user's location, time of day, recent activities, and the nature of the request to determine the appropriate response. This analysis happens locally on the device, utilizing the device's computational power without needing to send data to external servers in many cases.
2. Response Decision: Based on the gathered information and the user's query, Siri decides whether a spoken response is necessary. For instance, if the query requires a verbal response or confirmation, Siri will speak out loud. However, for simple tasks like setting an alarm or turning off a setting, Siri might execute the task without verbal confirmation.
3. Natural Language Processing (NLP): Siri uses natural language processing to understand the intent behind the user's request. It interprets the meaning of the query and formulates an appropriate response or action.
4. Voice Synthesis: When a verbal response is needed, Siri generates the spoken response using a combination of pre-recorded phrases and synthesized speech. The device's speech synthesis capabilities allow Siri to deliver responses in a natural and human-like manner.

The key aspect of Siri's on-device intelligence is its ability to handle many tasks locally, preserving user privacy by minimizing data sent to Apple servers while still providing a seamless user experience. This blend of hardware and software capabilities enables Siri to determine when to speak based on various contextual cues and user interactions.
