How to use Sound Recognition on iPhone
Jul 13, 2025 am 01:14 AM
The sound recognition function of iPhone supports iPhone 6s and later models, and needs to run iOS 14 or higher; the method of opening is to enter "Settings" → "Assistance Functions" → "Sound Recognition", turn on the switch and select the type of sound to monitor; when using it, you need to pay attention to problems such as battery consumption, environmental noise interference and limited types of recognizable sounds. This feature is suitable for hearing-impaired users or users who want to improve their convenience in life. Even if the lock screen is locked, it needs to maintain a network connection to support background recognition processing.
The sound recognition function of iPhone is actually quite practical, especially suitable for hearing-impaired users or to more conveniently sense surrounding sounds in daily life. It can detect specific sounds (such as doorbells, knocks, alarms, etc.) through the microphone and then remind you with notifications. This function does not require additional software, and the system comes with it.
Which iPhones support sound recognition?
Not all iPhones support this feature. "Voice recognition" has been added to iOS 14 and above systems, but the real usefulness is to upgrade from iOS 17. The currently supported models are mainly iPhone 6s and later models, as long as they are running iOS 14 or higher. If you are using the second generation of iPhone SE, iPhone 8 or newer models, the experience will be better.
To enable this function, first confirm whether there is a "sound recognition" option in your system settings.
How to turn on and set sound recognition?
The operation is actually not complicated, it can be done in just a few steps:
- Open Settings → Accessibility → Sound Recognition
- Turn on the switch and the system will prompt you to allow access to the microphone
- Then you can choose which sounds to monitor by default, such as doorbells, knocking, faucets, alarm clocks, etc.
After the setup is completed, the iPhone will silently monitor these sounds in the background. Once it is recognized, a notification will pop up to remind you. Even if the phone is locked, it will work, but it needs to keep the network connection (because part of the recognition is uploaded to the server for processing).
What should you pay attention to during use?
There are several details that are easy to ignore, but they are also very important:
- Battery consumption : Although sound recognition is running at low power consumption, it will still have a certain impact on the battery when it is turned on for a long time. If you often misidentify or don’t use it at the end of the day, you can consider opening it temporarily only when you need it.
- Ambient noise interference : In noisy environments, such as coffee shops or roadsides, the recognition accuracy may decrease. At this time, you can try to get closer to a little sound source or change to a quiet location.
- There are limited types of recognizable sounds : There are not many types of sounds currently supported, but Apple is also continuing to update. If you find that a common sound is not supported, you can provide feedback on the settings.
In general, this feature is suitable for users who want to improve the convenience of their lives, especially those with hearing impairments. It's not troublesome to set up, it's worth a try. Basically that's all, let's try it.

Apr 13, 2025 pm 11:15 PM
Apple's iPhone 17 may usher in a major upgrade to cope with the impact of strong competitors such as Huawei and Xiaomi in China. According to the digital blogger @Digital Chat Station, the standard version of iPhone 17 is expected to be equipped with a high refresh rate screen for the first time, significantly improving the user experience. This move marks the fact that Apple has finally delegated high refresh rate technology to the standard version after five years. At present, the iPhone 16 is the only flagship phone with a 60Hz screen in the 6,000 yuan price range, and it seems a bit behind. Although the standard version of the iPhone 17 will have a high refresh rate screen, there are still differences compared to the Pro version, such as the bezel design still does not achieve the ultra-narrow bezel effect of the Pro version.
