Speech to text Use cases
From commonplace use on house phones to applications in fields like marketing, finance, and medicine, speech to text has rapidly expanded. Voice to text technology can improve the efficiency of basic operations and expand to duties that humans have traditionally handled, as demonstrated by speech recognition apps.
Accessibility
- Captioning and subtitles allow more people, especially the deaf, to watch.
- Transcribing meetings, podcasts, and interviews makes information analysis and sharing simpler.
- Supplying live event captioning in real time: allowing listeners who are unable to hear the speaker clearly to follow along.

Uses in Business
- Creating speech-enabled assistants: enabling voice commands to be used to interact with gadgets and apps.
- Examining consumer calls: Recognizing patterns, attitudes, and possible problems in consumer encounters.
- Call transcription for customer support agents: Supplying real-time transcripts so that agents can better comprehend and address the demands of customers.
Medical Care
Transcribing consultations and patient notes: increasing accuracy and streamlining medical paperwork.
Medical records using voice dictation: facilitating the documentation of patient data by physicians and nurses.
Education
Offering lecture and instructional video transcripts: increasing the accessibility and interest of the information.
Using speech-to-text software to learn a language: assisting pupils in honing their pronunciation and understanding.
Media content search
Amazon transcribes audio and video files into archives that can be searched. Additionally, it enables users to enhance the accessibility and reach of content by producing localised subtitles in conjunction with Amazon Translate.
One of the top sectors using media content search to convert speech to text is marketing. Marketers may now learn about data patterns and consumer behavior to the advent of voice search.
For instance, speech recognition interprets age, location, and other crucial data while providing details about people’s vocabularies and accents. In order to remain ahead of trends, marketers can use conversational keywords because speaking is a lot more conversational search mode.
Media subtitling
With the digital scribe feature, Amazon transcribe may now record meetings and discussions, increasing accessibility, productivity, and the efficiency of crucial notes.
Clinical documentation
Medical practitioners can use Amazon Transcribe Medical to rapidly and effectively record clinical conversations into electronic health record systems so they can be analyzed. For instance, voice-activated customer care in banking uses speech to text. Speech-to-text technology facilitates data input and instant access to information, which increases efficiency in the healthcare industry.
Which kinds of speech-to-text technologies exist?
Speech to text technology comes in two primary varieties:
- Speaker-dependent: Mostly utilised for dictation programs.
- Speaker-independent: Frequently utilised in mobile applications.
To work properly, these two speech recognition systems need software and services, the most common of which is built-in dictation technology. Nowadays, dictation software is integrated into a lot of gadgets, including tablets, computers, and smartphones.
Speech-to-text applications
Software for speech to text can be used for a variety of purposes:
- Agent assistance and call centre insight
- Real-time transcription and translation services
- Voice recognition
- Voice typing and dictation apps
- Content monitoring
Agent assistance and call center insight
Automated transcription of customer interactions, call routing, sentiment analysis, and insight extraction from customer conversations are all possible using speech-to-text software.
For instance, AI voice assistants in customer service call centres can use speech to text to answer simple, routine consumer enquiries while referring more complicated enquiries to human agents.

Real-time transcription and translation services
It is capable of creating dubbings, subtitles, and captions for videos as well as transcribing minutes from webinars and online meetings. It can also be used to provide multilingual transcription of documents when combined with a translation program. Applications with specialised functions may enable transcription for use in legal, medical, and educational settings.
For instance, a medical transcription service provided by Amazon (link outside of IBM.com) uses speech to text to record doctor-patient discussions for clinical records and to entitle telemedicine encounters.Ten
Voice recognition
Voice recognition uses natural language processing to perform actionable commands from transcribed text. Chatbots like Alexa, Cortana, Google Assistant, and Siri can let users make calls, browse the web, and control smart home devices like lighting, thermostats, and more.
Amazon’s Alexa now uses text-to-speech and speech-to-text to control lights, temperature, and offer recipes based on recent purchases.
Voice typing and dictation apps
These applications enable those with disabilities to interact with cellphones and computers without the need for physical typing. They can dictate emails, notes, texts, and more instead.
For instance, on a Microsoft computer, students with dyslexia or those who have recently had arm injuries can still type notes by speaking. Azure Speech services provide the power behind this capability.
Content monitoring
AI can act as a moderator, flagging dubious information for human review after combing through audio and video transcripts to look for objectionable content.
What are the speech-to-text limitations?
The following are some of the primary drawbacks of speech-to-text technology, which is not without flaws:
- It isn’t perfect: Although dictation technology is a very effective tool, there are still certain shortcomings in its overall functionality because it is still in its infancy. Because it only generates text that is exactly as it is, you may wind up with a transcript that is clunky or wrong or that omits certain quotes.
- Needs human input: For best use, some human changes to the voice data are necessary due to the incomplete accuracy of speech to text.
- Clean recordings are required: The recorded audio must be clear and understandable in order for speech recognition software to produce a high-quality transcript. One person speaking at a time, clear pronunciation, no accents, and no background noise are all necessary for this. Additionally, voice commands for punctuation must be provided.
How to choose free speech to text software vs. paid?
Software that converts speech to text is useful if money is tight. But you’ll need more powerful software if you want to convert a lot of audio to text. In addition to having more features and support, paid speech-to-text software is frequently faster and more accurate.
The majority of free speech to text programs:
- Do not provide high-quality technical assistance.
- don’t provide the fastest or most accurate speed.
- has a finite amount of capacity.
- need a great deal of more editing from you.

How to choose the best speech to text software?
There are various speech-to-text software options, making selection difficult. Use this checklist to choose the best speech-to-text program:
- It doesn’t require any extra software. The most accessible speech-to-text software only needs an internet connection.
- A certain level of accuracy is guaranteed by all speech-to-text services. Certain providers guarantee more accuracy by putting more of an emphasis on transcription.
- Support for multiple languages: If you require multi-language support, you must select a speech-to-text program that satisfies your linguistic requirements.
- App compatibility is crucial if you want to utilise the program on several platforms. Some speech-to-text services can be integrated into apps.
Resources and Libraries:
Various tools and libraries for achieving speech-to-text functionalities are:
- Python packages like PyAudio and SpeechRecognition include functions like recognize_google to convert audio to text.
- IBM Watson Speech to Text and Google Cloud Speech-to-Text use deep learning algorithms for accurate transcription.
- An open-source deep learning engine is Mozilla DeepSpeech, and CMU Sphinx uses HMMs and other methods.
