Samsung keyboards do not have built-in microphones, and you cannot add one to the physical device
A Samsung keyboard — whether wireless, Bluetooth, or USB — is a hardware input device with no internal space or electrical capacity for a microphone. You cannot physically attach or install a microphone into the keyboard itself. If you need voice input on your Samsung device, you will use the microphone that already exists on your phone, tablet, or computer, or you will connect a separate external microphone to your device.
The confusion often comes from Samsung's voice input features, which work through your device's existing microphone, not through the keyboard. Your Samsung phone has a microphone built into the body. Your Samsung tablet has one. Your computer has one, either built in or as a separate USB device. The keyboard is just the tool you type with — it does not need to capture audio.
Key Takeaways
- Samsung keyboards have no microphone slot, port, or internal space to add one, because they are designed only for typing input.
- Voice input on Samsung devices uses the microphone already built into your phone, tablet, or computer, not the keyboard.
- If your device's built-in microphone is broken or too quiet, you can connect an external USB or Bluetooth microphone directly to the device, separate from the keyboard.
- Samsung's voice typing feature activates through the keyboard's spacebar or through your device's voice assistant, but the audio is captured by your device's microphone, not the keyboard.
How voice input actually works on Samsung devices
When you use voice typing on a Samsung phone or tablet, you press the microphone icon on the keyboard's spacebar or open Google Assistant, and your device's built-in microphone captures what you say. The keyboard itself is just the interface — it tells your device to start listening, but it does not do the listening. The microphone that records your voice is the small hole on the edge or back of your phone or tablet.
On a Samsung computer or laptop, the same principle applies. If you use voice typing in Microsoft Word, Google Docs, or another process, the microphone built into your monitor, laptop, or a separate USB microphone does the recording. The keyboard is not involved in capturing audio at all.
If you want to use voice input and your device's microphone is not working, the problem is not the keyboard — it is the microphone. You would need to repair or replace the device's microphone, or connect an external one.
When you actually need an external microphone
You need a separate microphone if your Samsung device's built-in microphone is damaged, too quiet, or if you want better audio quality for voice calls, video recording, or voice typing. External microphones connect directly to your device via USB, 3.5 mm headphone jack, or Bluetooth — not through the keyboard.
Popular external microphone options for Samsung devices include USB microphones like the Blue Yeti or Audio-Technica AT2020USB, which plug into a USB port on your computer or tablet. For phones, you can use a Bluetooth microphone or a wired microphone with a USB-C or 3.5 mm adapter. These microphones work alongside your keyboard, not as part of it.
If you are using a Samsung keyboard with a computer and want to record audio, you would plug the external microphone into the computer's USB port or audio jack, just as you would if you were not using a Samsung keyboard at all. The keyboard and microphone are completely separate input devices.
Troubleshooting a Samsung keyboard that seems to have no voice input
If your Samsung keyboard does not have a microphone icon on the spacebar, it may be an older model or a basic keyboard model without voice typing support. Samsung's newer keyboards, especially those designed for tablets and phones, often include a microphone icon that activates voice input. If yours does not, you can still use voice typing by opening Google Assistant or another voice app directly on your device.
To use voice typing on a Samsung phone, open any text field, tap the microphone icon on the on-screen keyboard, and speak. You do not need the physical Samsung keyboard to do this — the on-screen keyboard will have the microphone button. If you are using a physical Samsung keyboard connected via Bluetooth, the microphone icon on the spacebar (if present) straightforward triggers the same voice input feature.
If the microphone icon on your keyboard's spacebar does not work, the problem is usually a Bluetooth connection issue or a software setting, not a missing microphone in the keyboard. Reconnect the keyboard to your device, restart both devices, and check that voice input is turned on in your device's settings.
What you can do instead of adding a microphone to the keyboard
If you want hands-free voice input while using your Samsung keyboard, use your device's voice assistant instead. On Samsung phones and tablets, press and hold the home button or say "Hi Bixby" to set up Bixby Voice. On any Android device, say "Hey Google" to set up Google Assistant. Both of these use your device's microphone, not the keyboard, and they work whether the keyboard is connected or not.
For computer use, Windows has Cortana and Google has Google Assistant for Chrome. Mac has Siri. All of these set up voice input through your device's microphone or an external microphone you have connected — again, the keyboard is not part of the process.
If you want to record audio, take voice notes, or make video calls while using your Samsung keyboard, the audio will be captured by your device's microphone or by an external microphone you have plugged in. The keyboard will not interfere, and you do not need to modify it.
Checking whether your Samsung device's microphone is working
Before you assume you need to add a microphone to your keyboard, test your device's built-in microphone. On a Samsung phone or tablet, open the Voice Recorder app, tap the record button, speak a few words, and play it back. If you hear yourself clearly, the microphone is working. If the recording is silent or very quiet, the microphone may be blocked by dust or a case, or it may be damaged.
On a computer, open Sound Settings (Windows) or System Preferences (Mac), go to the Input section, and select your microphone. Speak into your device and watch the input level meter. If it moves when you speak, the microphone is working. If it does not move, the microphone is not being detected.
If your device's microphone is not working, you have two options: clean the microphone hole with a soft brush or compressed air, or connect an external USB or Bluetooth microphone. Neither of these involves the keyboard.
Frequently Asked Questions
Can I connect a microphone to my Samsung keyboard via Bluetooth?
No. Samsung keyboards do not have Bluetooth pairing capability for microphones. A Bluetooth microphone would pair directly with your Samsung device (phone, tablet, or computer), not with the keyboard. The keyboard and microphone are separate devices that both connect to your main device independently.
Does the Samsung keyboard's microphone button actually record audio?
The microphone button on the spacebar does not record audio itself. It tells your device to start listening through your device's built-in microphone or an external microphone you have connected. The button is just a trigger, not a recording device.
What if I want to use voice typing but my device's microphone is broken?
You will need to repair or replace your device's microphone, or connect an external USB or Bluetooth microphone directly to your device. The keyboard cannot help with this. Once your device has a working microphone, voice typing will work through the microphone button on the keyboard or through your device's voice assistant.
Is there a Samsung keyboard model with a built-in microphone?
No Samsung keyboard model has a built-in microphone. All Samsung keyboards are input devices for typing only. Voice input on Samsung devices always uses the microphone built into the device itself or an external microphone connected to the device.
Can I use a USB microphone with my Samsung keyboard?
Yes, but they work independently. A USB microphone plugs into your computer or tablet's USB port, and your Samsung keyboard plugs into a different USB port or connects via Bluetooth. Both devices connect to your main device separately. The keyboard does not need to be involved in microphone use at all.
