If you’ve used virtual assistants like Alexa, Cortana, Google Assistant, or Siri, you might be familiar with speech/voice recognition and conversational AI concepts. Speech recognition is the technology that enables users to explain themselves verbally to a device. It does that by converting the users’ verbal queries into machine-readable text.
As voice recognition technology might be used more than simply playing your favorite song on Spotify, its top 11 uses in marketing, customer service, healthcare, and other areas are reviewed in this article.

Common applications
1. Voice search
Voice search is, arguably, the most common use of voice recognition. Reportedly, in 2022, in the US alone, 135.6M users would have used a digital assistant at least once a month.
Moreover, according to a PWC survey, using a voice assistant to search for something was the preferred method of 71% of participants. 1
2. Speech-to-text
Voice recognition enables hands-free computing. Its use cases include, but are not limited to:
- Writing emails
- Composing a document on Google Docs
- Automatic closed captioning with speech recognition (i.e., YouTube)
- Automatic translation
- Sending texts

3. Voice commands to smart home devices
Smart home devices use voice recognition technology to carry out household tasks, such as turning on the lights, boiling water, adjusting the thermostat, and more.
Some statistics of smart home devices are:
- By 2028, the revenue of the market for smart home devices is projected to reach $231M.
- 30% of voice assistant users state that smart home devices are their primary reason(s) for investing in Amazon Echo or Google Home.
- By 2025, 478M households will have a smart home device.

4. Customer service
Voice recognition is an important AI application in customer service. Voice recognition is an effective call center service solution, available 24/7, and is cheaper than live reps.
The common use cases of speech recognition in customer service are:
- Interactive Voice Response (IVR): It is one of the oldest speech recognition applications and allows customers to reach the right agents or resolve their problems via voice commands.
- Analytics: Transcription of thousands of phone calls between customers and agents helps identify common call patterns and issues.
5. Pre-sales
Sales Development Reps (SDRs) calls can be wasteful. An example would be insurance companies calling their leads and asking them questions (i.e., their age, occupation, lifestyle, etc.) to see which insurance package they’d qualify for.
Such processes could be automated with voice bots. The benefit is that the caller will not have to wait to be connected with a sales rep. Rather, the bot will immediately start the evaluation and qualification process.
6. Voice biometrics for security
Similar to how your smartphone allows you to unlock it with your fingerprints, vocal biometrics uses a person’s speech to authenticate them. Users might be required to say their name aloud during log-ins rather than typing a password.
Alternatively, speech biometrics can be used in Fintech to authorize transactions and to guarantee they are genuine and consented to by the account owner. Besides, speech biometrics can restrict access to authorized personnel in healthcare, where maintaining patient confidentiality is of utmost importance.
Industry applications
7. Automotive
In-car speech recognition systems have become a standard feature for most modern vehicles. Research has shown that by 2022, 73% of drivers will use an in-car voice assistant.
The biggest benefit of car speech recognition is that it allows the driver to keep their eyes on the road and hands on the wheels. Use cases include initiating phone calls, selecting radio stations, setting up directions, or playing music.
8. Academic
80% of sighted children’s learning is through vision, and their primary motivator is to explore the environment around them. Speech recognition can create an equitable learning platform for children with no/low sight.
Language learning tools such as Duolingo use speech recognition to evaluate users’ language pronunciation. Pronunciation evaluation is a practical computer-aided language learning application.
9. Media/marketing
Speech recognition tools, such as dictation software, can enable people to write more words in less time. A study conducted by doctors using dictation software. Doctors could write 150 words a minute using a dictation tool.2
So, approximately, content creators writing articles, speeches, books, memos, or emails can transcribe 3000-4000 words in 30 minutes using these applications.
These tools aren’t 100% accurate, but they are good for first drafts.
10. Healthcare
MD note-taking
During patient examinations, doctors shouldn’t worry about taking notes of patients’ symptoms. Medical transcription (MD) software uses speech recognition to capture patient diagnosis notes.
It’s been claimed that taking notes is one of the most time-consuming activities for physicians, taking their time away from seeing patients.3 Thanks to MD technology, doctors can shorten the average appointment duration and, in return, fit more patients into their schedules.
Diagnosis
Depression speech recognition technology listens to a patient’s voice to identify the existence, or lack thereof, of depression undertones through words such as “unhappy,” “overwhelmed,” “bored,” “feeling void,” etc.
Vendors, such as Sonde Health, have created mobile applications that give users a score of “mental fitness” based on their voice’s tone, use of words, energy, fluctuations, and rhythm, among other variables.
11. Legal tech
Legal chatbots have grown in popularity because of their ease of use and wide applicability. Speech-enabled legal tech can expand the use cases to
- Court reporting (Realtime Speech Writing)
- eDiscovery (Legal discovery)
- Automated transcripts in depositions and interrogations
- Using NLP to review legal documents to determine if they meet regulatory criteria.
