On a Mac, or does your call platform run in the browser? Terpside is also a Chrome extension.

  1. Install and open

    Double-click the installer. Terpside opens in a separate window designed for your second monitor.

  2. Choose what to listen to

    In the source selector, choose the app playing the call (apps currently playing audio are marked) or your audio device.

  3. Interpret as usual

    Bubbles appear when each person finishes speaking. The first time you open Terpside you will see “Preparing this computer…”: it checks what it can use for recognition (the processor or the graphics card) and prepares the graphics card, which can take a couple of minutes. Wait for it to finish before starting a call; later starts are much faster.

What's new in this version

  • The latest turn always stays in view, even when its translation arrives a moment later.
  • A single turn of the mouse wheel no longer takes you out of the conversation; if you scroll up to reread, Terpside goes back to following it after 12 seconds without touching it.
  • More faithful numbers: Spanish “cuarto” no longer turns into “4th”, and “unos”/“unas” are no longer read as “one”.
  • New speech recognition, faster and more accurate: on medical sentences over the phone it gets more than 93% of words right.
  • Tested on real calls: it captures more of the conversation than the previous version and hardly falls behind, even on modest computers.
  • Works without a graphics card: it uses a single processor core.
  • Numbers, dates and phone numbers in digits: “March 25th 1985”, “555, 123, 4567”.
  • Personal glossary: add your own terms with their translation; the program flags them and recognizes them better.
  • Each sentence shows up as soon as it is recognized, and the translation follows right after instead of holding it back.
  • Optional: text while speaking, in a provisional bubble that corrects itself (⚙ → Performance → “Text while speaking”).
  • Lighter installer.
  • If you already have Terpside, install the new version over it: your settings, license and glossary are kept. From this version on, the program tells you when a new one is out.

    In Terpside's top bar, click “Free · activate Pro”. Settings open at the License section.

Requirements

Speech recognition and translation use the processor. Performance depends on your computer.

Operating systemWindows 11, 64-bit. On Windows 10, per-app capture needs build 20348 or later; on earlier builds the whole device is captured.
ProcessorMinimum: 4 cores; with 4 it works in the light profile (measured on a Ryzen 5 3500U laptop). Recommended: 6 cores (a recent Ryzen 5 or Core i5). 2 cores are below the minimum: on a 3rd-generation Intel laptop even the lightest profile is at its limit with clean speech, and it falls behind in real calls. Terpside says so on screen.
Memory8 GB of RAM.
Disk spaceAbout 1.1 GB once installed: the installer ships the models inside.
GPUNot needed: the default recognizer (Moonshine) runs on the processor. If you choose the Whisper engine in ⚙ and there is a graphics card (Intel or AMD integrated graphics, or NVIDIA), Terpside can use it through Vulkan.
Other requirementsWebView2 (included with Windows 11) and audio output through headphones or speakers.

About the load on your computer

If recognition falls more than a few seconds behind, Terpside drops the oldest audio to catch up with the present, and you will see it as a gap in the history. This may be caused by CPU or GPU load (for example, from a game or virtual machine), audio capture or the computer itself.

The thresholds Terpside uses to decide how much of your computer to spend were measured on a desktop (a Ryzen 5 3600 with 32 GB and an RTX 2060) and checked on two laptops (a Ryzen 5 3500U and a 3rd-generation Intel); that is not a campaign across a range of computers. That is why it does not ask you: at startup it measures your computer, picks the gear by itself and, if the result is tight, tells you in the bar instead of running slowly in silence. You can fix the gear by hand in Settings → Performance.

On a Mac? Terpside works in Chrome

If your call platform runs in the browser, the Chrome extension does what the Windows program does: it listens to the call tab and recognizes and translates on your computer, in Chrome's side panel. Free: 60 minutes a day, with the same Pro license.

Add to Chrome

Requires Chrome 137 or later. It only hears Chrome tabs: if your call runs in an installed program, it cannot hear it. We have measured it on Windows but not yet on a real Mac: if you try it there, tell us how it goes.

Is your platform an installed program?

That needs a desktop Terpside for Mac, which does not exist yet. Leave your email and we will let you know when it is out. We will use it for nothing else.
