Mobile browsers can hear your microphone, but not the meeting on your phone

While testing Speechara.AI on mobile, we ran into a limitation that was not obvious at first.

On desktop, Speechara.AI can capture system audio from Zoom, Google Meet, Webex, and other meeting apps, then transcribe and translate the conversation in real time.

Mobile browsers work differently. On both iOS and Android, they can usually access the microphone, but they cannot reliably capture system audio from an online meeting playing on the same phone.

Using the microphone as a workaround does not solve the problem. Mobile operating systems intentionally reduce or suppress speaker audio during calls to prevent echo.

This forced us to define the mobile experience more honestly. The mobile web version works for in-person meetings, lectures, and seminars. For an online meeting running on the same device, desktop remains the reliable option.

It is also one of the reasons we decided to build native iPhone and Android apps. Sometimes a platform limitation cannot be fixed with another browser workaround.

If a platform blocked an input your product depended on, did you narrow the use case, build a native app, or redesign the workflow?
