Push to Talk is a communication feature, not a file-opening setting

Push to Talk (PTT) is a way to send voice messages or make calls where you hold down a button to speak and release it when you stop — like a walkie-talkie. It is not a program that opens files by default. If you arrived here looking for which software handles Push to Talk, you are looking at the wrong category.

Push to Talk is a communication method built into certain messaging and calling apps. It does not compete with other programs to open documents, images, or media files the way a web browser or photo viewer does. The confusion often happens because some apps that support PTT also handle other file types, but PTT itself is a feature within those apps, not a default handler.

If you are trying to change which app opens your files — like which program plays your videos or displays your photos — you want the file-opening defaults section. If you are trying to understand what Push to Talk is or which apps offer it, this section explains that instead.

Key Takeaways

  • Push to Talk is a voice messaging feature inside communication apps, not a program that opens files.
  • Common apps with Push to Talk include WhatsApp, Telegram, Slack, and some two-way radio apps.
  • PTT settings live inside each app's messaging or calling menu, not in your device's file-opening defaults.
  • If you want to change which app opens a file type, look for file associations or default apps in your device settings instead.

Apps that include Push to Talk as a feature

Several popular messaging and communication apps have added Push to Talk in recent years. WhatsApp added a PTT button to its messaging interface, letting you hold it down to record a voice message that sends when you release. Telegram offers the same — a voice message button that works like PTT. Slack includes a voice message feature for team communication. Signal, a privacy-focused messaging app, also supports voice messages sent the same way.

Two-way radio apps and professional communication software often use Push to Talk as their main feature. Apps like Zello, Voxer, and Motorola Solutions apps are built around PTT functionality. These are designed for teams that need when ready voice communication — construction crews, security teams, delivery drivers, and emergency responders often use them.

The key point: Push to Talk is a feature inside these apps. It is not a separate program that opens files. When you use PTT in WhatsApp, you are still inside WhatsApp — you are not launching a different app to handle voice messages.

Where to find Push to Talk settings in your app

If you have an app that supports Push to Talk and want to turn it on or off, the setting is usually in the app itself, not in your device settings. Open the app, look for a messaging or settings menu, and search for "voice message" or "Push to Talk" in the options.

In WhatsApp, for example, the voice message button appears next to the text input field in any chat. In Slack, voice messages are sent through the message composer. In Telegram, the microphone icon in the message area handles voice messages. Each app places this feature slightly differently, but it is always within the app's own interface.

If you cannot find the feature in an app you thought had it, check the app's help documentation or settings menu. Some apps let you turn PTT on or off, and some require a certain version of the app or operating system to support it.

The difference between Push to Talk and file-opening defaults

File-opening defaults are what your device uses when you tap or double-click a file — like which app opens a PDF, which plays an MP4 video, or which displays a JPG photo. These are system-level settings on your device, usually found in Settings or Preferences.

Push to Talk is not a file type and does not have a default handler. It is a feature inside an app. You cannot set PTT as a default for anything because it is not competing to open files. If you are trying to change which app opens videos, photos, or documents, you need to look at your device's file associations or default apps settings, not at communication apps.

The confusion sometimes arises because an app like WhatsApp can handle multiple things — it sends text messages, makes calls, and sends voice messages via PTT. But each of those is a separate feature within WhatsApp. None of them are file-opening defaults in the way a browser or media player would be.

If you meant to find file-opening defaults

If you are actually trying to change which program opens a specific file type on your device, go back to your device settings and look for "Default apps," "File associations," or "Open with" options. On Windows, this is usually in Settings under Apps. On Mac, it is in System Preferences under General. On Android or iPhone, it varies by device and file type.

You can usually also right-click or long-press a file and choose "Open with" to pick a different app for just that file, or to change the default for all files of that type. That is where you set whether videos open in VLC, Photos, or another player — not in Push to Talk settings.

Frequently Asked Questions

Is Push to Talk the same as a voice message?

Push to Talk and voice messages work the same way in most modern apps — you hold a button, speak, and release to send. The term "Push to Talk" comes from two-way radio, where you literally push a button to transmit. In messaging apps, the terms are often used interchangeably now.

Can I set Push to Talk as my default for opening audio files?

No. Push to Talk is not a file handler. It is a feature for sending voice messages within an app. If you want to change which app plays audio files, look for default apps or file associations in your device settings, not in PTT options.

Do I need to read Push to Talk separately?

No. If an app supports Push to Talk, the feature is already built in. You do not read it as a separate program. You just open the app and use the voice message or PTT button in the messaging interface.

Why does my app not have a Push to Talk button?

Not all messaging apps include this feature. Some older apps or lite versions may not support it. Check your app's settings or help section to see if it offers voice messages. You can also update the app to the latest version — older versions sometimes lack this feature.

Can I use Push to Talk on a computer?

Yes, if the app has a desktop version. WhatsApp, Telegram, Slack, and others have Windows and Mac versions that support voice messages. The button or keyboard shortcut for PTT may be different on desktop than on phone, so check the app's help documentation.
