Why does Apple's 7siri reading accelerate?

Maybe there's something wrong with the system. You can find the reading speed in the settings, and then in the auxiliary function, you can adjust the speech speed of siri.

_I is the acronym for Speech Interpretation & Recognition Interface, which originally means speech recognition interface, and it is the voice assistant applied by Apple on iPhone, iPad, iPod Touch, HomePod and other products. Through Siri, users can find information, make phone calls, send information, get directions, play music, find Apple devices and so on.

_iri can support natural language input, and can call the weather forecast, schedule, data search and other applications that come with the system. It can also learn new sounds and intonations continuously and provide conversational response. Siri can transform iPhone4S and above (tablets above iPad 3) into intelligent robots.
