Enhance Your Models with Automatic speech recognition (ASR)

Automatic Speech Recognition.

Automatic speech recognition (ASR) technology is significantly impacting the world. This technology already transforms how students learn, employees work, and society functions. ASR also creates opportunities to assist specific communities of individuals, such as those navigating life or their studies with disabilities. While ASR is a valuable tool many people use daily, not everyone understands how it works or why it’s so helpful. Misconceptions about the role of ASR and its capabilities persist. Delve deeper into what this technology is, how it works, use cases of ASR, how it transforms industries, and how Macgence can help you with ASR solutions.

What is ASR?

Artificial intelligence is changing the way we teach, learn, and work. Automatic Speech Recognition (ASR) is a subset of AI that uses AI & ML to convert spoken words into written words (Speech to Text) and written language (Text to Speech). It is expected to expand to billions of dollars by 20 by 2028 at a CAGR of 6.0%.

ASR technology uses machine learning (ML) and artificial intelligence (AI) to convert human speech into text and vice versa. It’s a standard technology we encounter daily – think Siri, Okay Google, or any speech dictation software. 

How ASR Works

Most ASR voice technology begins with an acoustic model to represent the relationship between audio signals and the basic building blocks of words. An acoustic model transforms sound waves into bits that a computer can use. From there, language and pronunciation models take that data, apply computational linguistics, and consider each sound in sequence and context to form words and sentences.

Simply put, ASR follows a set of steps/processes, which are:

  • An individual or a group speaks, and the ASR software detects this speech.
  • The device then creates a wave file of the words it hears. 
  • The wave file is cleaned to delete background noise and normalize the volume. 
  • The software then breaks down and analyzes the filtered wave file in sequences. 
  • The automatic speech recognition software analyzes these sequences and employs statistical probability, finally outputs the words we see as transcripts.
  • Some technology providers’ ASR service includes editing by professional human transcribers. Adding this layer to the process helps correct errors and achieve greater accuracy.

Some Key Examples of Automatic Speech Recognition Variants

Some Key Examples of Automatic Speech Recognition Variants

There are several different variants of automatic speech recognition (ASR) that are used in various applications. Here are a few examples:

  • Directed Dialogue

It is the elementary variant of the two, in which the machine needs you to respond using a specific word from a set list of choices. It can process directed response requests only, for example: “Do you wish to re-purchase an item, see other similar items, or speak to a voice executive?

  • Natural Language Conversations

It is the more advanced variant of the two, which is a combination of natural language understanding and automatic speech recognition, using natural language processing (NLP) technology, which can imitate a real-world open-ended chat conversation; for example, the system can visualize and interpret responses from a wide range of reactions, even before posing a question, “How can I help you today?”

  • Speaker-independent recognition

Here, the system is trained to recognize speech from any speaker, regardless of their characteristics. You’ll find it used in public information systems, such as automated customer service or IVR systems, which must be accessible to many users.

Exploring More Use Cases for Speech Recognition Technology

Exploring More Use Cases for Speech Recognition Technology

Apart from using the automatic speech recognition technology in chat-based software, there are other use cases of this exceptional technology. Here are a few of them:

  • Vehicle Speech Recognition

Today, we have the luxury of telling our car whom to call, which song to play, and where to set the destination. This all has become possible because of speech-to-text technology. This is a tremendous step in the safety aspect of your driving experience. By eliminating the need to interact physically with the screen, automatic speech recognition prevents loss of attention that may lead to an accident.

  • Transcription Services

ASR technology has streamlined transcription, allowing fast and accurate conversion of spoken content material into written textual content. This has benefitted journalism, legal, and scientific industries, in which precise and well-timed transcriptions are crucial.

  • Call Center & Customer Support

Centers have adopted automatic speech recognition systems to record customer interactions, allowing for better tracking, analytics, and quality control. By converting spoken conversations into text, ASR enables call center operators to review customer interactions and gain valuable insights to improve their services.

  • Language learning

ASR technology has revolutionized language learning by providing real-time feedback on pronunciation and spoken language skills. This allows learners to adjust their speech plans, receive instant correction, and improve their fluency.

Automatic Speech Recognition (ASR) Industry Impact

ASR has many unique applications. For example, speech recognition can help improve customer experience, operational efficiency, and return on investment (ROI) in finance, telecommunications, and unified communications industries. Here is how ASR is revolutionizing various industries:


Speech recognition is applied in the finance industry for applications such as call center agent assistance and trade floor transcripts. Automatic speech recognition transcribes conversations between customers, call center agents, or trade floor agents. The generated transcriptions can then be analyzed to provide agents with real-time recommendations. This adds to an 80% reduction in post-call time.

Furthermore, the generated transcripts are used for downstream tasks:

  • Sentiment analysis
  • Text summarization
  • Question answering
  • Intent and entity recognition


Contact centers are critical components of the telecommunications industry. You can reimagine the telecommunications customer center with contact center technology, and speech recognition helps.

As previously discussed in the finance call center use case, ASR is used in Telecom contact centers to transcribe conversations between customers and contact center agents, analyze them, and recommend call center agents in real-time. T-Mobile uses ASR for quick customer resolution, for example.

Unified Communications as a software (UCaaS)

COVID-19 increased demand for UCaaS solutions, and space vendors began focusing on using speech AI technologies such as ASR to create more engaging meeting experiences.

For example, ASR can generate live captions in video conferencing meetings. Captions generated can then be used for downstream tasks such as meeting summaries and identifying action items in notes.
