What Is a Speech Recognition Microphone?

The first speech recognition microphone was developed by Bell Laboratories in 1952. It was called the Pattern Recognition Machine and it worked by converting speech into text. This allowed people to transcribe live conversations, meaning that they could transcribe telephone conversations without the need for human operators to listen in on them.

Speech recognition microphones are now a common way for people to communicate with computers and devices.

The ideal microphone for speech recognition has to be highly sensitive, able to capture the subtle nuances of human voice and have a large dynamic range.

When you are looking for the best mic for speech recognition, it is important to consider such factors as the dynamic range, sensitivity, and noise level.

Buying guide Mics for speech recognition

With the growing popularity of speech recognition software, there is a lot of new features available on microphones. In this guide, we will go through some of the latest micro-features that are worth considering when going for a microphone.

Factors to consider when buying a microphone for speech recognition:

1. Microphone type

There are three common types of microphones: dynamic, condenser and USB

  • Dynamic microphones are mainly used for recording vocals. They have a cardioid pickup pattern and a cardioid polar pattern.
  • Condenser mics are used by sound engineers and sound producers in recording studios and sound reinforcement systems. They also find their way into home studios as well as live music venues because of their versatility in recording environments.
  • USB microphones can be connected to computers or laptops, but they are generally used by podcasters and gamers due to their affordability

2. Microphone sensitivity

Mic sensitivity is the easiest way to set up a microphone for speech recognition. You need to be able to take advantage of the microphone’s sensitivity so that it can recognize your voice commands even when you are being noisy.

Mic sensitivity is measured in dB SPL or dBV and ranges from 18dB SPL to 130dB SPL. The bigger the number on the mic, the more sensitive it is and better at recognizing your voice commands.

3. Mic Frequency Range

This is measured in Hz and goes from 20Hz to 20kHz

Mic Frequency Range is a feature that lets you choose how far the microphone can pick up sound. It affects how well the microphone will recognize your voice.

Microphones that have a wide frequency range are better and more expensive than those with a narrow range. This is because they are sensitive to signals from all over the spectrum.


How do I improve my voice to text recognition?

If you want to improve your voice to text recognition, the first step is to get a good microphone. In addition, you should avoid recording in a noisy place and speak slowly. The most important thing is consistency.

What is the best software speech recognition?

A software speech recognition is a tool that can convert speech into text or vice versa. It works by using natural language processing and speech-to-text conversion.

Dragon Professional is one of the most widely used software speech recognition solutions available today. It has been around since the early 80s and has seen continuous development since then.

It’s also compatible with all major computer operating systems and it’s only available in English, German, French, Italian, Spanish and Japanese languages.
