Similar but Different! Speech-to-text and Auto-caption
Speech-to-text and auto-caption is not the same things? Know the difference between both tools that help a lot for content making.
Video content is currently being used widely. Social media platforms are competing with one another to enhance the products they provide, and one such feature is the addition of auto-captioning for each post. However, did you realize that creating content also often involves the use of speech-to-text? What then defines both of them?
Although they both have the capacity to translate spoken words into written text, their functions and applications differ. Knowing the differences between these two technologies will help individuals, companies, and content creators optimize the potential for enhanced interaction and accessibility. Let's look into how to differentiate between auto-captioning and speech-to-text.
The auto-caption feature, which usually appears just below videos, helps in offering written explanations of the video's content. According to dictionary.com, an automatic caption is generated by a speech recognition system and displays as a text overlay on the lower half of the screen.
Auto-captioning use Automatic Speech Recognition (ASR) as its technique. Auto-caption can identify spoken words with the use of ASR; the sounds preceding and after the spoken word are then synchronized. In order to translate spoken words in videos into text that may be shown as captions in real time or after production, it requires advanced algorithms and machine learning techniques. Enhancing accessibility for those with hearing problems, non-native speakers, and in silence audiences is the main purpose of auto-captioning.
Speech-to-text is an application for speech detection that translates spoken words into text by using computational linguistics. Another term for it is computer speech recognition or speech recognition. Real-time transcription of audio streams for text display and action is possible with certain tools, programs, and gadgets. STT is a more flexible technology that may be applied in a variety of situations, such as transcribing audio, translating voice commands into text, or creating text from podcasts or meetings, in comparison with auto-captioning, which is mostly used for videos.
What makes auto-caption and speech-to-text is not the same things? Here’s why..
Types of auto-captioning
- Real-time auto-captioning, that generates captions in real time while someone speaks. It is often used for broadcasts and events, such webinars, conferences, and live streams, when captions need to appear instantly. In general, it can be applied for online classes, virtual meetings, live TV broadcasts, and live videos on social media.

Automatically generated, the captions are synchronized based on the video. used for pre-recorded media, including movies, TV series, YouTube videos, and online courses.
- Open and closed auto-captions
- Open Captions: Open captions are automatically part of the video and cannot be disabled by the audience. Wherever player or platform they are on, they are regularly in view.
- Closed Captions: Users are allowed to enable or disable them. On platforms like YouTube and Netflix, where users can switch between captions according to their preferences, closed captions are frequently used.
- Offline auto-captioning, Using previously recorded audio or video files, this sort of captioning can be created and applied offline. The process can be completed without an internet connection. Generally for offline video editing programs and offline scenarios involving no internet access.
Types of speech-to-text
- Dictation-Based Speech-to-Text:This technology is mostly used to translate spoken words into text, often in real-time. Users can speak freely as the software converts their words to text. Useful for transcribing emails, notes, and papers. Frequently used by professionals, authors, and voice-input based people with disabilities.

- Post-Event Transcriptioncreates a text transcript from spoken information by processing audio or video recordings that have been recorded after an event. When precision is more critical than speed, it is frequently used. Typically applied for recording audio from podcasts, interviews, courtroom evidence, or medical records.
- Voice Command Systems:STT detects and carries out commands based on spoken input in voice-activated systems. Certain commands are recognized by these systems, which then cause them to perform certain tasks like playing music, launching apps, or managing smart home appliances. Typically utilized for automobile entertainment systems, virtual assistants (like Siri, Google Assistant), and smart speakers (like Amazon Alexa, Google Home).
- Voice search enables users to talk rather than type when running web or app searches. To conduct search operations, it translates spoken inquiries into text. Can be used in mobile apps or for voice searches on Google, YouTube, and other websites. Often used for quickly, hands-free searches on smartphones or smart assistants.
- A program called Speech Recognition for Accessibility attempts to enable voice recognition for those with disabilities. It helps people who are physically unable to type to interact with computers and other devices using voice guidance. used for helping anyone with disabilities or problems with sight who need assistance writing, navigating, or accessing devices.Multi-Speaker Speech-to-Text, Advanced STT systems that have multiple speakers that are able to distinguish between each other and assign the right words to each speaker throughout a conversation. This is very helpful in situations such as interviews or meetings. Applied to court cases, business meetings, podcasts, and interviews.
- Language Translation Speech-to-Text, this type of translation converts speech to text and back into another language either in real time or post-event. Generally applied for multilingual conferences, international business meetings, or private language translation needs.
- Speech-to-Text Offline, this type of STT processes speech offline on the device and does not require an internet connection. When issues with privacy or connectivity come up, it might be helpful. Usually, STT capability is required for mobile apps or devices that are offline
Functions of auto-caption
The method of automatically creating text captions for spoken words in movies or live broadcasts is known as auto-captioning. Accessibility, multilingual accessibility, increased engagement, SEO advantages, higher comprehension, and real-time interaction are some of its main features. Auto-captioning improves search engine optimization (SEO), increases engagement in loud surroundings, makes video content accessible to those with hearing impairments, and helps audiences throughout the world understand content in languages they may not speak well.
Additionally, it enhances real-time interaction during live broadcasts and improves comprehension by bolstering spoken information with written words.
