# Voice conversations

> Shoppers can talk to your assistant out loud from the widget. Here is how microphone selection works and what to check if a call cannot hear the shopper.

Shoppers on desktop and mobile web can tap the microphone in the chat widget to speak to your assistant instead of typing. The assistant replies out loud in real time, and the conversation continues in chat afterward.

## Microphone selection

The widget asks the browser for whatever it considers the default microphone, the same approach every voice product uses. Most of the time this is correct.

On a shopper's work laptop, a conferencing app like Microsoft Teams or Zoom can install its own virtual audio device and quietly become the operating system's default microphone, even while the app is closed. Left alone, this makes the browser capture silence from the virtual device instead of the shopper's real microphone.

The widget checks for this: if the default microphone's name matches a known conferencing app (Teams, Zoom, and similar), it automatically switches to a real microphone on the same device when one is available.

## If a shopper still cannot be heard

* ask them to check their operating system's sound settings and confirm a real microphone, not a conferencing app's virtual device, is selected as the default input
* ask them to close any open conferencing app and reload the page
* confirm the site is loaded over HTTPS, browsers refuse microphone access on plain HTTP
