Delay and lag
You hear
Conversations keep overlapping because your voice, or theirs, arrives late.
Most call delay comes from the network: a distant server, busy Wi-Fi or a VPN. Some apps add a little delay of their own.
Likely causes, in order
Check them top to bottom. The room and the mic come first because no setting can remove what a closer mic or a closed door would.
| 01 · Layer | 02 · Likely cause | 03 · Fix |
|---|---|---|
| 01 · App | Voice activation waits for your voice before it starts sending | In Discord, use Push to Talk, which has relatively no delay when you press the key push to talk |
| 02 · App | Video is competing with your audio on a struggling connection | Turn your video off, or join the audio by phone, when the connection is poor video off |
| 03 · Network | A VPN routes the call through another location | Turn off the VPN for the call, or ask your IT team to let call traffic bypass it VPN off |
| 04 · Network | Wi-Fi is weak or crowded | Use a wired connection, or the 5 GHz Wi-Fi band wired |
| 05 · Network | The voice server, or the service location, is far from you or from the others | In Discord, pick a voice region between you and the people you talk to; for a work app, ask IT how call traffic is routed voice region |
| 06 · Network | The connection's latency is simply high | Check the call app's statistics; Zoom recommends latency of 150 ms or less ≤ 150 ms |
By app
- Discord
- Discord says Voice Activity has an inherent 200 ms delay, plus the distance to the voice server, while Push to Talk has relatively no delay when you press the key. A voice channel's region can be changed with Region Override.
- Zoom
- Zoom's meeting statistics show latency, the delay between a packet being sent and received. Zoom recommends 150 ms or less, with jitter of 40 ms or less.
- Google Meet
- Google says a VPN routes your traffic through another network location and can delay your meeting, and suggests a wired connection or the 5 GHz band. On a poor network, it suggests joining without video.
- Microsoft Teams
- Microsoft notes that sending Teams traffic through a VPN, or to a service location further from you, adds latency and jitter, and that Teams puts audio ahead of video when bandwidth is short.
Check it with the test
The noise test can't measure network delay: it only hears your mic. If the test sounds right and people still talk over you, check the call app's own statistics for latency, or try the call on a wired connection.

Q.01How much delay is too much?
Zoom recommends latency of 150 ms or less on its meeting statistics, with jitter of 40 ms or less and packet loss of 2% or less.
Q.02Will a faster internet plan fix the lag?
Not on its own. Speed and delay are different numbers: Google suggests watching latency over time as well as bandwidth, and Microsoft notes that a VPN or a distant service location adds latency.
Q.03Does push to talk reduce delay?
In Discord, yes. Discord says Voice Activity has an inherent 200 ms delay, while Push to Talk has relatively no delay when you press the key.
