Top 8 Best Mics for Speech Recognition in 2021 Review

If you want to establish when speech recognition first appeared, you could argue it was when Thomas Edison created the phonograph in 1877. In reality, if we are talking about speech recognition as we understand it today, it came much later. However, finding the best mics for speech recognition wasn’t an issue until quite recently.

The first systems were not as recent as you might think and were designed in 1952 but only to work with numbers. Very basic, of course, but it could recognize a voice repeating numbers.

IBM made Big Advances

Ten years after that, IBM put a lot of effort and expense into developing the computational linguistics department of their computer science operation. That came up with a basic answer they called the Shoebox. At the time, it was a revolution; it could understand and respond to sixteen words in English. For some, the “War of the Worlds” had arrived.

A dramatic increase in computer power and understanding of artificial intelligence has made this now part of everyday life. We have reached a situation today where science and capability are on a par with human performance. Google has broken through the threshold that was set at 95% accuracy.

What is the Key Element?

The software that is designed and operates speech recognition requires something to make it work. It needs an excellent quality of sound. The demands on the microphones are therefore very high.

They must not only create a reproduction of the highest quality. But they also need to be able to suppress the natural ambient noises generated in a workplace. For it to work well, the demands are high. So, let’s take a look at some of the best voice recognition mics currently on the market and find the perfect one for you.

1 Shure WH20XLR Dynamic Headset Microphone – Best Wired Headset Mic for Speech Recognition

Let’s start with a company that needs no introduction to anyone who knows anything about microphones. The first name on many people’s lips would be Shure.

Rugged but lightweight

It is built with a typical rugged Shure quality, but it is also lightweight, weighing only three and a half ounces. It is a dynamic mic that has a Cardioid pattern. That allows it to concentrate on the source of your voice and removes unwanted external noise.

It has an extra-strong cable that will resist damage. The cable is about four feet long. As this is a wired mic, you will have to stay close to your computer. All told, it’s one of the most durable speech recognition microphones on the market.

Speech accuracy

Dictation needs to be accurate, and for that, the sound collection has to be spot-on. Not everyone’s voice is the same. Therefore, there need to be built-in vocal corrections to ensure the reproduction has high quality.

This is achieved with a presence peak and a low-frequency roll-off. This means that the sound captured will be clear and accurate. Special attention here is given to the mids and higher frequencies because that is where the voice resides in the frequency range. This makes it is a mic that is excellent for speech recognition.

The frequency range is 50Hz – 15kHz. The sound is smooth and comparable to the highest-quality hand-held mics. One of the best hands-free speech recognition mics; it works well. Featuring a comfortable elasticated headband and a collapsible boom.

2 Dictaphone Nuance PowerMic II – Most Versatile Mic for Speech Recognition

Nuance is a multinational software company. They are based near Boston, Massachusetts, and provide artificial intelligence and speech recognition solutions. They merged with their main competitor, Scansoft, in 2005.

Easy to use

This is an easy-to-use system that connects via USB and operates as a plug-and-play installation. Controls are practical and are very visible, placed on the top of the handset. It has ten programmable options that give you complete control over your dictation requirements. One important added feature is the track-point control and the left and right mouse button.

An integrated interface

The Nuance PowerMic II is fully integrated for all Nuance speech recognition software. And is the preferred speech recognition microphone for medical practitioner software. This is especially applicable for Dragon Medical Practice Editions 1 and 2.

The Microphone

It has a tethered design with a USB connection that links directly to a laptop or computer. The connecting cable is about nine feet in length, so it gives you plenty of room. This helps any medical staff and gives them simple and direct thumb-controlled operations for dictation, review, and editing.

It relieves the burden of having to constantly shift between a mic and a keyboard. If you choose to use the mic while it is in its cradle, that can be set up. Although, you will have to stay fairly close to it to get a decent reproduction. It is a high-quality mic that has a very low noise factor. Not the cheapest option you will find but a quality product.

3 KLIM Rhapsody Desktop USB Microphone – Most Compatible Mic for Speech Recognition

The purpose of microphones where speech is delivered is simple. You want the person or the hardware you are speaking with to hear you clearly. That means a sharp and accurate transmission of the voice without background noise. And one of the big assets of this mic is that it delivers high-quality sound.

Plug and Play

You do not need extra drivers, PC accessories, or software to operate it, just plug it in. It is compatible with Mac OSX, Windows, Linux and also works on PS4 for gamers. As a result, it’s one of the easiest to use mics for speech recognition you can buy.

The Build

It has been given a very stable base that is durable, and so you don’t need to find or buy a mic stand. As it is a wired connection, you will have to stay quite close to your computer or another device. The cable for connection is about four feet long. Adequate when seated at a desk.

Conference Calls and Speech Recognition

It has a high-performance level when working with Speech Recognition software such as Cortana, Google Docs Voice, and Dragon Natural Speak. But it also functions well for use with Skype or other conference call software. However, it is very sensitive. You will have to ensure there is as little background noise around you as possible.

It has some RGB lights on the base. That might be fun for gamers but unlikely to impress those that are using it for serious work duties. It is limited in its functions to a certain extent. But if all you want is a basic mic that has speech recognition hooked up to your computer, it works well. Set at a very cost-effective price.

5 Philips SpeechMike Premium Air Wireless Dictation USB Microphone – Best Wireless Mic for Speech Recognition

Now we move a little further upmarket price-wise with this mic from Philips. This is a mic that performs as you would hope it might. Recordings give you a sound like they have been recorded using a mic many times the price.

The speech recognition uses this quality to produce near-perfect accuracy through the software. It has a free-floating mic that is a design that separates the mic away from the device to reduce any unwanted noise.


It is wireless but doesn’t use Bluetooth. It has a special “Lossless” technology. That allows you to move around without interfering with the operation. It also provides a superior transfer of your dictation into the software without even the smallest delays.

If you are looking for quality microphones, you usually do not have to look too much further than Sennheiser. This German company has for many years provided some of the best microphones for professional and other use. If you need a mic, then Sennheiser should be one of the first companies you look at.

Impressive Noise Cancellation

Best Mics for Speech Recognition Buying Guide

Best Mics for Speech Recognition

You will find that most of the specs for these mics are reasonably similar. There are, of course, higher specs that will cost more. But the big decision you need to think about is whether you need it to be portable.

“To Move or Not to Move” is the question

There is a considerable difference in price between those that are mobile and those that need a fixed position. The mobile mics are suited to more specific operations. The mics used in one place, on a computer desk, are usually used for other applications.

If you opt for the mobile option, you should check the battery life of the unit. You don’t want it running out too quickly.


If you are going for the mic that is static on a desk and connected to a computer, do you need a headset? If your usage involves a conversation, then you probably will. It’s worth looking at the headset options with a view to how comfortable they are.


The more expensive mics come with built-in features that allow you to search and edit your work. This may be important. Some also allow you to pull up previous documents. In some situations in the work environment, these options will be essential.
