From July 15, 2022, Zoom will have a 40-minute limit even for meetings with two participants if you have a free subscription. (Previously, it was only for meetings with 3 or more people.)
Companies and organizations using Zoom for business should consider switching to a paid license at this opportunity. 

Many people may have experienced that their voice was interrupted during a Zoom meeting. If the sound is interrupted all the time in a meeting or class, stress builds up, and you may have trouble understanding the content of the conversation at all. In this article, we will explain the causes and how to deal with voice interruptions on Zoom.

The voice may be interrupted due to the network line

The voice may be interrupted due to the network line

The sound quality of web conferencing services such as Zoom depends on the network connection status. It may be easier to understand if you remember when you watch videos on Youtube or VOD. Many of you may have experienced that when you watch on your computer at home, you can hear clearly, but when you watch it on your smartphone on the go, the voice breaks up. Improving the network connection status will prevent the video and voice from being interrupted, and you will be able to watch without stress.

If the network connection is unstable, try the following measures.

  • Connect to wired LAN
  • Check if communication is restricted
  • Use Wi-Fi
  • Participate from a location with good signal
  • Remove anything that causes radio interference

Connect to wired LAN

A wired LAN is connected directly to a computer with a LAN cable, so communication is more stable than a wireless connection. If the voice is interrupted with a wireless connection, connecting to a wired LAN may improve the situation if the wired LAN is available.

Check if communication is restricted

When the data usage reaches the upper limit, the Internet connection speed is restricted and the speed drops significantly. Zoom meetings send and receive video and audio, so slow communication speeds can cause video and audio to be interrupted. If the communication limit is applied, change the connection method or review the plan.

  • Connecting to the network using methods other than mobile communication
  • Consider a higher plan if monthly limits apply

Participate from a location with good signal

A characteristic of mobile data communication is that the communication speed is affected by the radio wave conditions and the usage of other users in the vicinity. When using Zoom from a smartphone, tablet, or LTE model computer, it may be improved by moving to a place with a good signal or avoiding busy times.

Use Wi-Fi

In general, Wi-Fi is more stable than mobile data communication, which is affected by the radio wave environment, so you can secure speed. If you can connect to Wi-Fi, try switching to Wi-Fi.

Remove anything that causes radio interference

If your Wi-Fi frequency is in the 2.4GHz band, using a microwave oven will cause radio wave interference. If the network is interrupted while using the microwave, refrain from using the microwave during the Zoom meeting, or try moving away from the area where radio interference does not occur.

In addition, if the distance between the device and the Wi-Fi router is too far, or if there is an obstacle between them, the connection may become unstable. prize.

Does your PC/smartphone meet the system requirements for Zoom?

Does your PC/smartphone meet the system requirements for Zoom?

When you have a web conference with Zoom, the camera and microphone are also running, and the CPU usage rate will be high. If the specs of the device are high, you can do a lot of processing at the same time, but if the specs are not enough, Zoom will freeze if multiple processes are running at the same time, and video and voice will be interrupted. .

If your computer or smartphone lacks resources, try to reduce the load.

  • Use high spec devices
  • close unnecessary apps
  • Turn off virtual backgrounds, screen sharing, and camera

Use high spec devices

The higher the device specifications, the higher the processing power. It goes without saying that using a device with high specifications will make the operation smoother, not just for Zoom meetings.

Please check the operating environment of Zoom and use a terminal that meets the system requirements as much as possible.

Reference: Recommended processor and RAM requirements for Zoom

Below are the system requirements recommended by the Zoom Help Center.

the smallest Recommendation
processor Single core 1GHz or higher Dual-core 2Ghz or better (Intel i3/i5/i7 or AMD equivalent)
RAM N/A 4 Gb

close unnecessary apps

If you have multiple apps running at the same time on your computer or smartphone, the amount of CPU resources that can be allocated to Zoom will decrease, causing delays or freezes. It is a good idea to close unnecessary apps during the Zoom meeting.

Turn off virtual backgrounds, screen sharing, and camera

In Zoom, the CPU load is high for functions such as virtual backgrounds, screen sharing, and video transmission. Just turning off these functions may improve the operation, so if you don’t really need to use them, turning them off is one way.

Audio problems may be caused by problems with audio equipment

Audio problems may be caused by problems with audio equipment

If the audio is interrupted with Zoom, there may be a problem with the audio equipment such as the microphone or earphones you are using.

Clean your microphone, earbuds, and speakers

Microphones, earphones, and speakers have small holes for voice input/output. If dust or sebum are clogged here, problems such as inability to hear sound will occur. Clean regularly to remove dirt, oil, and other contaminants.

Try changing the mic and earphones

Microphones and earphones are also consumables. If you try to replace it with another device and it improves, it may be a malfunction or life.

Use wired audio devices rather than wireless ones

Equipment such as microphones, earphones, speakers, etc. may also cause radio wave interference when connected wirelessly, making the connection unstable. If anything, a wired device is more stable, so if you have it at hand, try switching to a wired device.

Zoom’s “noise suppression” setting also causes voice interruptions

Zoom's noise suppression setting also causes voice interruptions

Zoom has a noise canceling function called “noise suppression” that suppresses noise in the microphone voice and makes it clear.

At first glance, it looks like a useful function that removes noise, but it sometimes happens that a small voice is judged as “noise” and silenced, resulting in the voice being interrupted.

Disabling this function may improve the choppy sound, so please try it.

How to turn off the “Noise Suppression” function

  1. Sign in with the Zoom desktop client.
  2. Open Settings.
  3. Click “Audio”.
  4. Turn on Show in-meeting options to enable original sound.

Noise suppression is now disabled.

One thing to keep in mind when holding a Zoom meeting with this setting is that the noise is not removed and can be heard by other participants as it is, so if you join from a noisy place, the noise may increase and it may be difficult to hear.

In this case, use a high-performance microphone for better sensitivity, or join Zoom from a quiet location.

Summary of how to deal with voice interruptions

If your voice is interrupted on Zoom, it is effective to check the following four points.

  • Unstable network connection
  • Device specs, lack of resources
  • Problems with audio devices such as microphones, earphones, speakers, etc.
  • Zoom’s “noise suppression” feature

If you experience a problem with your voice being cut off during a Zoom meeting, first check the points above and try to deal with it.
