Speech recognition, believe it or not, has been around since the 1980s.

And over the last 40 years, thanks to some of the best speech recognition software AI like Siri, Alexa, Google Assistant, IBM’s Watson etc., it has improved by leaps and bounds in recognizing human speech.

Can the best speech recognition software available today effectively replace humans in transcribing audio or video files?

And which free, paid and online voice recognition apps and services help you do that efficiently and effectively?

Let’s find out.

DISCLAIMER: 

At the time of writing, while we’ve researched the best speech recognition software and listed them in this article, they work best with slow paced, clear, enunciated American accent dictation recordings by a single speaker with no background noise.

In addition, the person should be talking close to the microphone.

Even the best speech recognition software will oftentimes struggle if there’s:

  • Faint voice of the speaker
  • More than one speaker
  • Background noise or music
  • Overlapping conversation

Having said all that, advanced machine learning has made things easier over the last few years.

Below is a list of the best speech recognition software available today:

Accuracy

With over 15 years of experience in human audio transcription services, working with some of the best universities, individuals and companies in the world, we’ve gathered sizeable expertise in the field.

And that is evident in our verified Trustpilot reviews.

We’ve then used that expertise to train our speech recognition AI to reach state-of-the-art accuracy levels.

To be featured in this list of best speech recognition software in 2020, we had to work hard on making it able to differentiate between fast and slow pace of speech, different accents, and catch even the most obscure technical jargons.

Customizations to Increase Accuracy

Thanks to advanced machine learning, you can provide a base vocabulary or a glossary of terms to feed our speech recognition AI to generate more accurate transcripts for your project.

Using a mix of speech models, neural networks and algorithms, it learns specific words, phrases, technical terminology or names of individuals related to your niche.

Video transcription can use the same system to add quick closed captions or subtitles.

High Confidentiality

Unlike other online tools on this list, for example the ones from Google or Facebook, our speech recognition AI doesn’t process your confidential data online.

It’s processed on a separate device, and all of your sensit
