Live Captions on iPhone: a simple guide for videos and podcasts
Live captions on iPhone turn spoken words into on-screen text in real time, helping you follow videos, podcasts and FaceTime calls without needing to crank up the volume. The feature was introduced with iOS 16 and has been refined in every release since, including the latest version available across Australian networks. Whether you are catching a train through Sydney's CBD, working in a busy café in Melbourne, or just trying to watch a tutorial once the kids have gone to bed, automatic captions can make audio content far more accessible.
The technology relies on speech recognition that runs directly on the device for supported languages, which means transcripts appear quickly and your audio is not sent off to a remote server. This is an important distinction from older captioning systems, which depended on a steady internet connection and often lagged behind the speaker. Live captions also differ from standard subtitles baked into a video file. Traditional subtitles only show up if the creator added them ahead of time, whereas live captions generate text on the fly for almost anything you can play through your iPhone.
Australia has embraced captions faster than many markets, partly thanks to public broadcasters like SBS which have championed accessible media for decades, and partly because of high smartphone penetration in cities such as Brisbane, Perth and Adelaide. Recent surveys show more than nine in ten Australian adults now own a smartphone, and a large slice of those users rely on their device for news, sport and entertainment during the daily commute. That habit makes live captions especially handy when you forget your headphones on the bus or want to follow a podcast without disturbing fellow passengers on the train from Parramatta into the city.
This walkthrough covers everything from checking whether your handset supports the feature to tweaking caption appearance, fixing common glitches and understanding how privacy is handled under Australian law. You do not need any technical background to follow along. Each step has been tested on recent iPhone models running the latest iOS release available locally, so you can follow the instructions in order or jump to the section that solves your immediate problem.
What live captions actually do on your iPhone
Live captions use on-device machine learning to listen to audio playing through your iPhone, including speech from other people nearby when you use the microphone, and convert it into scrolling text. The text appears in a dedicated window that floats above whatever app you have open, so you can keep watching a video, scrolling social media or taking notes while still reading along. Unlike closed captions, which are pre-written and timed to specific moments, live captions are generated continuously and may occasionally mistranscribe names, technical terms or heavy accents.
The feature supports English across Australian, American and British variants, as well as several other languages including Mandarin, Japanese, French and German. When you first turn it on, you will be asked to confirm your preferred language and whether you want profanity to be filtered out. That second option is worth considering if you share your phone with younger family members or want to follow live sport commentary without the colourful language that often slips in during an NRL or AFL broadcast.
One of the most practical uses is following long-form podcasts while doing something else with your eyes, such as cooking dinner or going for a walk along the Yarra River in Melbourne. Because the captions sit on top of your screen, you can glance down to catch a quote without missing a beat of the audio. The window also resizes and can be dragged to different corners, which we will look at later in the customisation section.
Check your iPhone model and iOS version first
Live captions require at least iOS 16, which means any iPhone from the 11 onwards will work, including the second-generation iPhone SE released in 2020. Older handsets such as the iPhone X, 8 or earlier cannot run the feature because the neural engine needed for real-time speech recognition is missing. If you are holding onto a device that is more than five years old, this might be the push you need to upgrade, particularly because Apple continues to roll out security patches but cannot backport every new accessibility tool.
To find out which version of iOS your phone is running, open the Settings app, tap General, then tap Software Update. The screen will show the installed version at the top and offer a download if a newer build is available. Australian carriers such as Telstra and Optus do not gate iOS updates, but they do push carrier settings updates separately, so it is worth keeping those current if you rely on your phone for calls and mobile data. Keeping iOS up to date also ensures you have the latest caption improvements, including better handling of Australian place names and slang.
If your phone is running iOS 16 or later but the Live Captions toggle does not appear in Control Centre, it usually means the shortcut has not been added yet. The underlying software is ready to go, which is reassuring if you have just upgraded from an older handset.
Turn on live captions for videos and FaceTime
The quickest way to enable live captions is from Control Centre, which is the same panel you use to toggle Wi-Fi, brightness and music playback. On an iPhone with Face ID, swipe down from the top-right corner of the screen; on an iPhone with a Home button, swipe up from the bottom edge. Look for the Live Caption button, which looks like a small text bubble icon. If it is not there, tap the plus icon at the top-left of Control Centre, choose Add a Control, then scroll down to Hearing and select Live Captions.
Tap the Live Captions icon once and a window will appear at the bottom of the screen showing whatever is being said. The window grows as more text is captured and then shrinks after a few seconds of silence, so it rarely blocks the full video. You can pause the audio, rewind a few seconds using the built-in control, or tap the window to expand it into a larger reading view. The captions follow you across apps, so if you switch from a YouTube video to a FaceTime call, the text keeps streaming without needing to toggle anything.
For FaceTime specifically, live captions are useful when you are catching up with relatives in regional Queensland or Western Australia and the connection is a bit patchy. The text gives you a backup channel if the audio drops out for a moment. Group FaceTime calls also benefit, as the captions show whoever is speaking at that moment, marked clearly so you can keep track of the conversation in busy family chats.
Use live captions for podcasts and audio apps
Captions work just as well for audio-only apps, including Apple Podcasts, Spotify, Overcast and Pocket Casts, as long as the audio is playing through your iPhone. Start an episode, then bring up Control Centre and tap Live Captions. A text window will appear over the podcast artwork and begin transcribing the host's voice in near real time. It is a great workaround when you are in a shared office in Sydney's Martin Place and forgot your AirPods, or when you are following a true-crime series late at night and do not want to wake up the household.
There are a few limitations to be aware of. Live captions will not transcribe audio that is playing through a Bluetooth speaker or a wired headset that is not an Apple or Beats product, because the system needs access to the audio stream. If you are streaming from a smart speaker or a third-party app that does not route audio through the standard iOS player, the captions may not trigger. Australians buy wireless earbuds in large numbers thanks to aggressive retail competition between JB Hi-Fi, The Good Guys and Harvey Norman, so a supported pair is usually within reach.
Another point worth mentioning is that live captions are designed for one speaker at a time. Panel shows with overlapping voices can produce jumbled text, particularly if the hosts interrupt each other or there is audience laughter in the background. The transcripts are still useful for grabbing a quote or finding a specific moment to scrub back to, but they are not a perfect replacement for a written transcript.
| Caption method | Works with | Needs internet | Best for |
|---|---|---|---|
| Live Captions (iOS 16+) | Any app playing audio through the iPhone | No | Videos, podcasts, FaceTime, calls |
| Closed Captions (CC) | Apps with CC tracks | No | Movies and TV shows on Netflix, Stan, Disney+ |
| Subtitles & Captioning | Streaming apps with baked-in tracks | No | Pre-made subtitles in any language |
| Third-party apps | Depends on the app | Usually | Meetings, lectures, note-taking |
For the highest accuracy, Apple Music and Apple Podcasts both offer static transcripts for select shows, which you can read alongside the audio without needing live captions at all.
Customise how captions look and sound
Once you have turned on live captions, you can adjust how they appear by going to Settings, then Accessibility, then Live Captions. Here you will find toggles for profanity filtering, text size, background colour and text colour. Increasing the text size is a good idea if you read with the phone at arm's length on the tram, while a high-contrast yellow-on-black combination tends to work well in bright sunlight on a Bondi Beach walk.
You can also choose whether the Live Captions window appears at the top or bottom of the screen, and whether it stays expanded or collapses automatically. Some users prefer the always-expanded view because it feels closer to reading subtitles on a television, while others like the collapsible bubble because it gets out of the way during video playback. Try both for a day and see which feels more natural.
If you want captions to start automatically every time you make or receive a call, or whenever you launch a supported media app, look for the toggle labelled Live Captions in the Hearing section of Accessibility settings. Users who rely on captions due to hearing loss can also explore the broader Subtitles & Captioning menu, which controls closed captions in streaming apps. That menu lets you choose a default style that matches the live caption look, so the experience feels consistent no matter which app you are using.
Fix common problems with live captions
If live captions refuse to turn on, the first thing to check is whether the feature is restricted under Screen Time. Open Settings, tap Screen Time, then Content & Privacy Restrictions, and choose Allowed Apps. Make sure Live Captions is enabled. This setting is often overlooked when a phone is handed down to a child or set up by a workplace IT department.
Another common issue is captions appearing but staying blank or showing incorrect text. This usually happens when the audio is too quiet, when there is significant background noise, or when the speaker is using a strong regional accent that the speech model has not been trained on. Repositioning the phone closer to the speaker, or moving to a quieter room, typically solves the problem. Battery life can also take a hit if captions run for hours, because the neural engine is working constantly. If you are running low on charge and away from a power point, consider turning captions off until you need them.
Connectivity does not affect live captions because the processing is on-device, but your mobile data still matters for the videos and podcasts you are streaming. Australians in regional areas, particularly across the outback or in parts of Tasmania, sometimes rely on slower satellite or fixed-wireless NBN connections. Downloading episodes over Wi-Fi before you head out is usually cheaper and more reliable than streaming on the road.
Privacy, data and accessibility in Australia
Because live captions run locally on your iPhone, the spoken audio is not transmitted to Apple or any third party. This aligns well with the Privacy Act 1988 and the Australian Privacy Principles, which set strict rules about how personal information is collected and handled. If you ever needed reassurance that a private conversation is staying private, this is one feature where the architecture genuinely keeps your data on the device.
Accessibility is also a growing focus for Australian regulators and consumer advocates. The Australian Competition and Consumer Commission has highlighted the importance of inclusive design, and the National Disability Insurance Scheme continues to fund assistive technology for eligible participants. Live captions fall squarely within that category, providing a free, built-in tool that does not require any extra hardware or subscription. For people who are deaf or hard of hearing, the difference between guessing what a podcast host said and reading the exact words is significant.
