What Are the Advantages and Disadvantages of Speech Recognition?

June 6, 2024 Business

Using speech recognition software has some advantages, but also some disadvantages. 

Some of these advantages include time saving, ease of use, and accuracy. Some of these disadvantages include language input, and the requirement of language skills.

Speech Recognition Software

Using voice recognition software, you can easily dictate text onto a computer, tablet or smartphone. It can help those with physical disabilities or dyslexia write more accurately and free them from using a keyboard. It also makes it easier for people to communicate with others.

Speech Texter – Free

SpeechTexter is a free speech to text converter that converts spoken words into text in real time. It doesn’t need to be installed, and it’s built on Google’s high-end speech recognition engines. It works on all platforms, and you can use it for learning how to pronounce foreign words.

It can be used for language learning, or to practice speaking. To use it, you just need a microphone button and a computer that has a microphone.

Kaldi – Open Source

Kaldi is a speech to text converter that is free for Windows and Linux. It is built on the Apache License and is one of the few speech to text converters that are supported by leading technologies. It’s also known for its user-friendly interface. It’s highly customizable, too. You can add timestamps, adjust sound and speed, and e-mail your transcription. It is the highest quality standard in speech to text conversion.

Voice Texting Pro – iOS

Voice Texting Pro is another speech to text converter that supports multiple languages. It has a variety of in-app purchases, and works best on the iPhone 5. It has a professional look, and is a great app to use if you need voice texting for business purposes.

Speech Recognition on Android

Android offers several features to help developers add speech recognition to their apps. 

The Android SDK provides the SpeechRecognizer class, which can be used in conjunction with the RecognitionListener interface and other classes from the android.speech package to enable voice control of an app. 

The SpeechRecognizer can detect multiple languages and has built-in support for continuous speech recognition. It can also recognize spoken punctuation and symbols, as well as nonverbal commands, such as “yes” or “no”.

The Speech Recognizer is really easy to use: all you need to do is configure a few parameters (like the language) and then use it in conjunction with an event listener that will be triggered when the voice recognition has been activated. 

The listeners have a simple interface and all they need to know is how to setup the settings for speech recognition on their devices. 

You can also customize the sensitivity of the Speech Recognizer to better match your app’s specific needs.


Various factors can affect the accuracy of speech recognition. 

For example, a speaker’s age and accent can thwart the system’s ability to recognize speech. Another challenge is the number of variations found in human speech.

These variations include speech sounds, inflections, and accents. Fortunately, recent advances in artificial intelligence have made it possible to develop speaker-independent speech recognition. 

The technology uses self-supervised learning models, allowing the system to learn more about the speakers’ voices and adjust its accuracy.

One of the most important advances in speaker-independent speech recognition is deep learning. This technology utilizes neural networks as feature transformations. 

By utilizing faster processors and cheaper memory, the system can increase its vocabulary size and recognition accuracy. In addition, deep learning has decreased word error rates by 30%.


Despite the popularity of voice recognition technology, there are some disadvantages to using it. 

While the automatic speech recognition may be the star of the show, it can still be a bit of a challenge to implement. For example, it may not be able to capture all words accurately because of pronunciation variations, or it may not be able to sort through background noise. 

If this is the case, it may be best to rely on a more accurate (and more expensive!) transcription service.

Using automatic speech recognition can be an advantage in some industries, such as the law industry. It can help lawyers reduce time spent on legal research and documenting their cases, and ensure the accuracy of their work. It also allows for more efficient internal processes. However, many users are still hesitant to use an ASR bot for sensitive tasks, for the reason we’ve mentioned above – lack of accuracy.

There are still many factors to consider before implementing automatic speech recognition in your office. For example, you must ensure that your office equipment is capable of recording quality audio, and that your software can accurately read the text produced.

Although the technology can make documentation easier, it can also result in errors. For instance, the system may not understand accents or slang. It may also take longer than anticipated to capture words correctly.

Some users are worried that they will not be able to trust the voice recognition system. They are hesitant to use ASR bots for sensitive tasks. The lack of trust may cause businesses to hesitate in adopting this technology.

The technology is also expensive to implement. This may include special hardware and software. Depending on the application, it may also require significant training. There may also be regulatory requirements.

Voice recognition software can be a distraction. It may not be able to differentiate between ambient noise and the actual speech. 

Wearing a noise-canceling headset may help. Also, people who speak in accents need to learn to speak clearly so the system can recognize them. People must also avoid talking in a choppy manner or mumbling. This can lead to grammar and spelling errors.

Speech recognition may also have data privacy concerns. It is important to consider how a speech recognition system will handle your personal information. This information may include sensitive financial or medical information.

Then, it is often necessary to train your employees in the proper use of automatic speech recognition. This includes developing a training program based on different scenarios. A training program can also include a number of other features, such as filtering out background noise.

A Little Bit of History

During the early part of this decade, a wave of voice recognition applications exploded onto the market. 

These applications are typically very easy to use, and allow consumers to interact with technology in a manner that is most convenient for them. It also provides a means for people with limited use of their hands to work with computers. 

In addition to a variety of voice-enabled business applications, speech recognition technology has also been used to help make driving safer.

But the history of speech recognition dates back to the early 1950s. In 1952, Bell Labs developed a speech recognition system that could recognize digits spoken by a single voice. 

However, this system was not quite as accurate as modern technology and this system was capable of recognizing 16 English words. 

Over time, by 2001, the technology had reached 80% accuracy and improved vastly. However, it still has a long way to go. 

The history of speech recognition also includes the introduction of mel-frequency cepstral coefficients, a classical frame-based feature extraction method. Mel-frequency cepstral coefficients were originally used to recognize speech, but they eventually became standard for many speech-enabled applications.

The latest speech recognition technology relies on artificial intelligence (AI). 

Advanced speech recognition software utilizes neural networks, grammar, and structure. These technologies enable the software to recognize words that are spoken in a variety of languages. 

The software is also trained on different accents and speech patterns. This technology can even be used to analyze emotion. For example, a speech recognition system can use its analysis of vocal characteristics to determine whether a person is sad, excited, or satisfied.


Let’s focus on positive things – Speech recognition has become an important tool for many professionals. This software is also installed on a variety of devices, including mobile phones. 

Speech recognition has also been used in the medical field. It can help clinicians to perform their dictation tasks more quickly.
